11.2 Precautions on rating
Avoid using in exceeded the rated temperature range, rated voltage, or rated current.
Usage when the ratings are exceeded could lead to wire breakage, burning, or other serious fault.
11.3 Inrush current
If an inrush current (or pulse current or rush current) that significantly exceeds the rated current is applied to the product,
overheating could occur, resulting in wire breakage, burning, or other serious fault.
12. 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.
Also, if repeatedly subjected to temperature cycles or other thermal stress, due to the difference in the coefficient of thermal
expansion with the mounting substrate, the solder (solder fillet part) in the mounting part may crack.
The occurrence of cracks due to thermal stress is affected by the size of the land where mounted, the solder volume, and the
heat dissipation of the mounting substrate. Carefully design it when a large change in ambient temperature is assumed.

12.3 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 100°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.

* 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.
12.5 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.

12.6 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.
a
b
〈 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
(1) Turn the mounting direction of the component parallel to the
board separation surface.
A > D*1
(2) Add slits in the board separation part.
A>B
(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.
(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.
12.7 Handling of substrate
(1) The stress applied to the chip varies depending on the material and construction of the mounted substrate.
If the coefficients of thermal expansion for the substrate and chip vary significantly, the difference in thermal expansion and
shrinkage could cause cracks to form in the chip.
We assume that the products are mounted on glass-epoxy substrate. Assessment has not been conducted on substrates
where the coefficient of thermal expansion varies significantly from glass-epoxy substrates. If mounting on these
substrates, be sure to conduct full assessments before use.

(2) 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.
Also, if mounting on flexible substrates, excessive mechanical stress could be applied to the chip by even slight bending or
twisting when handling this substrate, and so please conduct full assessments before use.

Twisting
12.8 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) Perform ultrasonic cleaning under the following conditions. Exercise caution to prevent resonance phenomenon in
mounted products and the PCB.

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.
12.9 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 may cause the poor
solderability.
• 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.
• Do not keep products in bulk packaging. Bulk storage could result in collisions between the
products or between the products and other parts, resulting in chipping or wire breakage.
• Avoid storing the product by itself bare (i.e. exposed directly to air).
Transportation
Excessive vibration and impact reduces the reliability of the products. Exercise caution when
handling the products.
12.10 Resin coating (including moisture-proof coating)
Before applying any resin coating, please consult our technical department.
12.11 Mounting conditions
Check the mounting condition before using.
Using mounting conditions (nozzles, equipment conditions, etc.) that are not suitable for products may lead to pick up errors,
misalignment, or damage to the product.
12.12 Operating environment
Do not use this product under the following environmental conditions as it may cause deterioration of product quality.
(1) In the corrodible atmosphere such as acidic gases, alkaline gases, chlorine, sulfur gases, organic gases and etc.
(the sea breeze, Cl2, H2S, NH3, SO2, NO2, etc)
(2) In the atmosphere where liquid such as organic solvent, may splash on the products.
(3) In the atmosphere where the temperature/humidity changes rapidly and it is easy to dew.

12.13 Mounting density
If this product is placed near heat-generating products, be sure to implement sufficient heat-dissipating measures.
If this product is subjected to a significant amount of heat from other products, this could adversely affect product quality,
resulting in a circuit malfunction or failure of the mounted section. Also, be sure that the product is used in a manner so that
the heat that the product is subjected to from other products does not exceed the upper limit of the rated operating
temperature for the product.
