10.2 Precautions on rating

Do not use the products in excess of their rated current. Doing so may cause the product to generate heat, resulting in short

circuit between wires, wire breakage, or melted solder, which may cause dropping of parts.

10.3 Fail-safe

Be sure to provide an appropriate fail-safe function on your product to prevent a second damage that may be caused by the

abnormal function or the failure of our product.

11. Precautions for Use

This product is for use only with reflow soldering. It is designed to be mounted by soldering. If you want to use other mounting

method, for example, using a conductive adhesive, please consult us beforehand.

11.1 Land dimensions

The following diagram shows the recommended land dimensions for reflow soldering.

The land dimensions are designed in consideration of electrical characteristics and mountability. Use of other land

dimensions may preclude achievement of performance. In some cases, it may result in poor solderability, including positional

shift. If you use other land pattern, consider it adequately.

11.2 Flux and solder used

Flux

• Use a rosin-based flux that includes an activator with a chlorine conversion value of 0.06(wt)% to 0.1(wt)%.

• Do not use a highly acidic flux with a halide content exceeding 0.2(wt)% (chlorine conversion value).

• Do not use a water-soluble flux.

Solder

• Use Sn-3.0Ag-0.5Cu solder.

• Standard thickness of solder paste: 150 μm

If you want to use a flux other than the above, please consult our technical department.

11.3 Soldering conditions (reflow)

• Pre-heating should be in such a way that the temperature difference between solder and product surface is limited to 150°C

max.

Cooling into solvent after soldering also should be in such a way that the temperature difference is limited to 150°C max.

Insufficient pre-heating may cause cracks on the product, resulting in the deterioration of product quality.

• Standard soldering profile and the limit soldering profile is as follows.

The excessive limit soldering conditions may cause leaching of the electrode and/or resulting in the deterioration of product

quality.

11.4 Reworking with soldering iron

The following requirements must be met to rework a soldered product using a soldering iron.

3 s (+1 s, -0 s)

2 times max.

Number of reworking operations

* Avoid a direct contact of the tip of the soldering iron with the product. Such a

direction contact may cause cracks in the ceramic body due to thermal shock.

11.5 Solder volume

Solder shall be used not to increase the volume too much.

An increased solder volume increases mechanical stress on the product. Exceeding solder volume may cause the failure of

mechanical or electrical performance.

11.6 Product's location

The following shall be considered when designing and laying out PCBs.

(1) PCB shall be designed so that products are not subject to mechanical stress due to warping the board.

[Products direction]

Products shall be located in the sideways direction (length: a < b) to the mechanical stress.

Poor example

〈

〉

Good example

〈

〉

(2) Components location on PCB separation

It is effective to implement the following measures, to reduce stress in separating the board.

It is best to implement all of the following three measures; however, implement as many measures as possible to reduce

stress.

Contents of measures

Stress level

A > D^*1

A > B

(1) Turn the mounting direction of the component parallel to the

board separation surface.

(2) Add slits in the board separation part.

(3) Keep the mounting position of the component away from the

board separation surface.

A > C

*1 A > D is valid when stress is added vertically to the perforation as with hand separation.

If a cutting disc is used, stress will be diagonal to the PCB, therefore A > D is invalid.

Spec No.: JELF243A_9147E-01

P8/9

(3) Mounting components near screw holes

When a component is mounted near a screw hole, it may be affected by the board deflection that occurs during the

tightening of the screw.

Mount the component in a position as far away from the screw holes as possible.

11.7 Handling of substrate

After mounting products on a substrate, do not apply any stress to the product caused by bending or twisting to the substrate

when cropping the substrate, inserting and removing a connector from the substrate or tightening screw to the substrate.

Excessive mechanical stress may cause cracking in the product.

Bending

Twisting

11.8 Cleaning

The product shall be cleaned under the following conditions.

(1) The cleaning temperature shall be 60°C max. If isopropyl alcohol (IPA) is used, the cleaning temperature shall be 40°C

max.

(2) Excessive ultrasonic oscillation during cleaning can cause the PCBs to resonate, resulting in cracked chips or broken

solder joints. Before starting your production process, test your cleaning equipment / process to insure it does not degrade

this product.

(3) Cleaner

Alcohol-based cleaner: IPA

Aqueous agent: PINE ALPHA ST-100S

(4) There shall be no residual flux or residual cleaner. When using aqueous agent, rinse the product with deionized water

adequately and completely dry it so that no cleaner is left.

* For other cleaning, consult our technical department.

11.9 Storage and transportation

Storage period

Use the product within 12 months after delivery.

If you do not use the product for more than 12 months, check solderability before using it.

Storage conditions • The products shall be stored in a room not subject to rapid changes in temperature and humidity.

The recommended temperature range is -10°C to +40°C. The recommended relative humidity

range is 15% to 85%.

Keeping the product in corrosive gases, such as sulfur, chlorine gas or acid, oxidizes the

electrode, resulting in poor solderability or corrosion of the coil wire of the product.

• Do not keep products in bulk packaging. Doing so may cause collision between the products or

between the products and other products, resulting in core chipping or wire breakage.

• Do not place the products directly on the floor; they should be placed on a palette so that they are

not affected by humidity or dust.

• Avoid keeping the products in a place exposed to direct sunlight, heat or vibration.

Transportation

Excessive vibration and impact reduces the reliability of the products. Exercise caution when

handling the products.

11.10 Resin coating

The inductance value may change due to high cure-stress of resin to be used for coating/molding products.

A wire breakage issue may occur by mechanical stress caused by the resin, amount/cured shape of resin, or operating

condition etc. Some resin contains some impurities or chloride possible to generate chlorine by hydrolysis under some

operating condition may cause corrosion of wire of coil, leading to wire breakage.

So, please pay your careful attention when you select resin in case of coating/molding the products with the resin.

Prior to use the coating resin, please make sure no reliability issue is observed by evaluating products mounted on your

board.

P9/9

11.11 Handling of product

• Sharp material such as a pair of tweezers or other material such as bristles of cleaning brush, shall not be touched to the

winding portion to prevent the breaking of wire.

• Mechanical shock should not be applied to the products mounted on the board to prevent the breaking of the core.

11.12 Handling with mounting equipment

• With some types of mounting equipment, a support pin pushes up the product from the bottom of the base (paper) tape

when the product is sucked with the pick-up nozzle.

When using this type of equipment, detach the support pin to prevent the breaking of wire on the product.
