POLYMER MULTI-LAYER CAPACITORS

PMLCAP

Ⓡ

CAUTION FOR PROPER USE OF PMLCAP

Ⓡ

Upon using PMLCAPⓇ, please pay attention to the points listed below.

Catalog may be subject to change without notice.

1. APPLIDE VOLTAGE

1) Rated voltage

As for applied voltage to capacitors, sum of DC voltage and peak AC voltage should not exceed their own DC rated

voltage.

2) Voltage derating

Within category temperature range, capacitors can be used without voltage derating.

3) Use in high frequency

Using capacitors at high frequency will be shortened its life due to the generation of heat. Please consult us in this

case.

4) Use in special wave-form

If you want to use capacitors with a special wave-form other than a sine wave, please inquire to us for details after

identifying the wave-form with which the capacitor is required to be used, because the eﬀective value varies with

wave-form.

2.GUARANTEE OF CAPACITANCE TOLERANCE

PMLCAP characteristics may ﬂuctuate by surroundings.Even if left in natural condition, capacitance may ﬂuctuate by humidity.By

Ⓡ

considering it, the product shall be shipped with special care at factory. But the guarantee of capacitance tolerance shall be

applied once before opening the humidity proof bag. It shall not be applied when individual agreement is exchanged.

3. PERMISSIBLE CURRENT

1) Permissible current for frequency

Please contact us in advance.

2) Permissible peak current (pulse current)

If you want to use capacitors with a special wave-form other than a sine wave, please inquire to us for details after

identifying the wave-form with which the capacitor is required to be used, because the eﬀective value varies with

wave-form.

4. SELF HEAT RISE

Please conﬁrm self heat rise within 10℃.

5. OPERATING TEMPERATURE

Use capacitors within the speciﬁed temperature range.

If used outside the speciﬁed temperature range, then the electrical characteristics may deteriorate signiﬁcantly, leading

to failure.

The temperature referred to here includes the ambient temperature including heat produced by heat generating devices

(power transistors, resistors, etc.), self heating due to ripple current.

6. SOLDERING

1）Soldering method

●MU series, MS series, MR series

MU series, MS series and MR series shall be used in reﬂow soldering and ﬂow solderingꢀmethoed. Do not use in

VPS soldering method.

●ST series

ST series shall be used in only reﬂow method. Do not use in ﬂow, dipping and VPS soldering method. Please conﬁrm

your reﬂow conditions (reﬂow time, temperature). Soldering conditions should be according as recommended reﬂow

temperature proﬁle.

●LDT series

LDT series shall be used in only ﬂow method. Do not use in reﬂow and VPS soldering method.

2）MSL

Moisture Sensitive Level (MSL) which is based on IPC/JEDEC J-STD-020D is showed in the following table.

※

Floor life time (hours)

※Floor life time is the case of humidity control under 30℃60%RH.

3）Solder paste (Chip type)

A recommended thickness of solder paste is between 0.1mm to 0.2mm. The content of halogen in the soldering ﬂux

should be 0.1wt% or less.

4）Tentative mounting (Chip type)

This product can not be used again when the double-stick tape is used for tentative mounting.

No preheat

・Soldering under above conditions should not be repeated for a same part.

・Please keep above conditions when reworking is need after reﬂow soldering.

・Do not hit the tip of soldering iron to the capacitor directly.

・Do not reuse the capacitor.

・Please contact us in advance if your condition is diﬀerent with above.

7. CLEANING SOLVENTS

Please contact us in advance when cleaning of the PC board after soldering is necessary. If used improper cleaning

agent and/or ultrasonic, the capacitor may be damaged.

8. STORAGE CONDITION

①MU series/MS series/MR series/ST series: Please store capacitors under the normal temperature (5～30℃) and normal

humidity(70%RH or less) without operating of moisture-proof bag.

ꢀStorage time limit (the state that a zipper of a moisture-proof bag was closed with dry silica gel) is within 1 month from

opening of moisture proof bag (Temperature: 5 to 30℃, Relative humidity: 70% or less). But, when the humidity of the

ambient environment keeps below 5%RH, it's possible to treat as the unopened position of moisture proof bag.

②LDT series: Please store capacitors under the normal temperature (5～30℃) and normal humidity(70%RH or less) .

9. CONDITION OF USE

The following environment should be avoided when using capacitors.

①Damp conditions such as water, saltwater spray, or oil spray or fumes. High humidity or humidity condensation

situations.

②Hazardous gas/fumes (hydrogen sulﬁde, sulfurous acid, nitrous acid, chlorine, ammonia, bromine, etc.)

③Exposure to ozone, ultraviolet rays or radiation

10. DISPOSAL

In case of rejecting capacitors, please seek for professionals who deal with the industrial wastes management.
