INTRODUCTION

Because soft ferrite, such as MOFe₂O₃(M:bivalent metal), in the high-frequency range has high

magnetic permeability, a large degree of saturation magnetic flux and large characteristic

resistance compared to metallic magnetic materials, it is extremely populer as a high-

frequency compound.

As switching power supplies rapidly become more compact and thinner, requirements for ferrite

as a high-frequency transformer material are becoming increasingly stringent.

To meet these demands, NEC TOKIN has enhanced its lineup of ferrite cores by adding the

BH1 and BH2 types (-300 kHz) which feature improved core loss over the B25 type (-300

kHz), and B40 (500 kHz -1 MHz) with improved core loss in high frequencies.

Further, the requirements of larger power supply capacities, increasing thinness and high

density mounting are met by the E,FPQ, FEP, FEER and FQK Series, as well as the

surface-mounting FEY Series.

●E type cores

This series features 46 shapes and sizes from FEI 12.5 to

FEE60W, standard-equipped with accessories for accommo-

dating different transformer specifications.

●FPQ type cores

This series features eight shapes and sizes suitable for high

density mounting.

●FEER type cores

This series features 19 shapes and sizes with greater winding

cross-sectional area than the E and FPQ types.

●FEY type cores

This series features htree shapes and sizes suitable for ultra

high-density mounting.

Precautions Before Use

Notes on Design

12) Take note of the following information when selecting mem-

bers (bobbin, metal fittings, tape, adhesives, saturants, and coat-

ings) to use in combination with the ferrite core.

1) When selecting the material and shape for the ferrite core,

strictly observe the limits given in the catalog (product manual)

regarding such things as the L value, maximum saturation, mag-

netic flux density, and core loss.

1

2

Members that do not corrode or react.

Members with coefficients of thermal expansion as close

as possible to ferrite.

3

4

Members that do not add thermal shock (such as casting

chemicals).

2) Select a ferrite core having temperature and frequency proper-

ties for the core loss that meet the demands of the equipment to

be used.

Members that can withstand transformer heat genera

tion, and particularly those that do not were down wires.

3) Abnormal heat release may result if used under high frequen-

cies or in strong magnetic fields. Select a ferrite core that has the

appropriate properties such as a low core loss.

13) The coefficients of thermal expansion for the ferrite core and

bobbin differ greatly. Securing the core and bobbin with satu-

rants and adhesives will cause the bobbin to expand from heating

when the adhesive hardens or heat release during operation.

This will place stress on the core, possibly causing it to break.

Allow sufficient clearance between the core and bobbin.

4) In an environment where the Curie point is exceeded, the fer-

rite core may lose its intrinsic properties, causing the equipment

to malfunction. Use only in a temperature range that stays below

the Curie point.

14) When there is unbalance from a circuit being split two or

more times, the flux will concentrate on the side where the flow is

the easiest and may result in abnormal heating and even fire.

5) Give careful consideration to the balance of the ferrite core's

thickness when designing a shape.

6) When designing a bobbin, set measurements and select bob-

bin materials that meet the requirements (frame class, thickness,

HWI, HAI, HVTR, CTI, and D495) of safety standards such as

UL.

15) When a bifilar wiring is made by, for example, a wire con-

tainer, and the wire gage and length is different or the number of

coils are different, the electrical current will tend to flow in only the

easiest way, resulting in heating and fire.

7) Working on the coil could destroy the ferrite core owing to the

coil's thickness or damage the coil itself, so designs should pro-

vide adequate clearance between the core and coil.

16) Designs should keep abnormal current resulting from a prob-

lem in another circuit from flowing into the transformer.

8) For inserting the ferrite core into a case, designs should pro-

vide adequate clearance between the core and case. The core

may break unnecessary force is applied.

17) When used as a transformer, heat will be released. Designs

should ensure that surrounding parts will not deteriorate or be

destroyed by that heat.

9) The insulation resistance of the ferrite core is not high. Do not

use it as an insulator. Also, do not use it for other purposes (such

as electrical circuit element).

18) Regarding equipment where the user is able to touch the

core, make sure to provide extensive warnings and instructions

to the user so they will not get shocked or burned by touching the

core.

10) For ferrite cores that have low resistivity such as Mn-Zn

cores, make sure to provide sufficient insulation with insulation

protection covers and tape, etc.

11) When resins such as adhesives, saturants, and coatings are

used, excessive stress may arise in the ferrite core owing to the

difference in coefficients of thermal expansion, resulting in the

core breaking. It is best not to use such resins, but if their use

cannot be avoided, use one with a coefficient of thermal expan-

sion that is close to that of the core. In addition, select non-corro-

sive resin for the core and members to be used.

19) Since leakage flux may cause equipment to malfunction,

check in advance for its effects on the equipment you are using

and ueardy equipment, and then take the appropriate actions.

12) The ferrite core should be kept away from rapid temperature

changes, corrosive gases, dust, and humidity. Care should also

be taken to isolate it from vibration when transporting and storing

it.

Notes of Caution on Handling and Us-

age

1) The ferrite core is a sinter. Make sure to handle it carefully as

it has low tolerance for impact such as being knocked or dorpped,

which may cause it to break or chip. Using it without realizing that

it is broken will result in degradation of its properties and heat

release. In addition, chipped fragments may result in injury or

even get into the eye.

13) Impact may cause the inductance of ferrite cores to change.

14) If the ferrite core is magnetized once by a strong magnet, it

may lose its prescribed properties.

15) If the ferrite core is used for a coil, wrap the wire with the

tension appropriate for the core's thickness and the tapering

shape. Applying tension beyond the prescribed amount when

wrapping the coil may break or chip the core.

2) The ferrite core is a magnetic substance. When there is a

strong magnet nearby, the core will be quickly attracted to it, and

there is the possibility that the core will be destroyed by the im-

pact. There is also the danger that a finger or the like may be

crushed between the two.

16) When the ferrite core is directly used for a coil, the wire may

be damaged by the burr on the core's surface, resulting in a short

circuit. Select a core that has had its burr removed or has been

coated.

3) The ground surface of the ferrite core has sharp edges be-

cause it is not beveled so as to prevent decreased performance.

In addition, there may be a minute amount of burr. Carelessly

touching it may lead to injury.

17) When the ferrite core is directly used for a coil, the wire may

be damaged by tension or friction, resulting in a short circuit. The

wire may also be damaged by kinks or the jigs and tools used

when adjusting the transformer. Take adequate care when per-

forming work.

4) Do not apply force to the ferrite core beyond the prescribed

amount. Otherwise, the core may break or chip the core.

5) Do not allow the ferrite core and jigs or two cores to collide.

Failing to observe this may destroy the core(s).

18) When wrapping a coil or during assembly, adjust the equip-

ment so that the core is not struck hard and no excessive stress is

applied, and make sure to handle it as delicately as possible.

6) When securing the ferrite core, do not apply stress beyond the

necessary amount. Failing to observe this may break or chip the

core, reducing its properties.

19) The ferrite core should not be placed in the mouth. Make

sure to keep it away from young children.

7) Do not expose the ferrite core to rapid temperature extremes

(thermal shock). Failing to observe this may break or chip the

core.

20) Use the ferrite core under normal temperatures and in nor-

mal surroundings.

8) When performing molding or such, the core may break or chip

on account of rapid changes in humidity and expansion differ-

ences between resins. Carefully evaluate the materials you

iutend using.

21) If core fragments or other debris get in the ferrite core's

ground surface, inductance will lower and howling will result.

22) When cutting the ferrite core, take measures to prevent injury

such as providing a cover or protector so that debris and chips

will not fly in all directions. In addition, note the following informa-

tion to prevent the core from breaking or chipping.

9) There are some ferrite cores that are heavy. Packing boxes

may fall over if stacked too high. Limit the height when stacking

them.

1

2

3

4

Select a grindstone with the properties for the core's quali

ties.

10) There are some ferrite cores that are heavy. When

movingtheir packing boxes, take due care to prevent injury or

backache.

Adjust cooling agents and their conditions (amount, tem

perature, and quality).

11) Since there is the possibility of damage by vibration, falling,

or other sources of physical shock when transporting ferrite cores

and transformers that use these cores, take care to provide ad-

equate packing to prevent such damage.

For shapes that require a large amount of grinding, do not

grind all at once. Instead, grind a little bit at a time.

Use an exhaust system to prevent the aspiration of dust

produced when cutting the ferrite core.
