Guidelines and precautions regarding the technical information and use of our products described in this online catalog. 

m= If you want to use our products described in this online catalog for applications requiring special qualities or reliability, or for applications where the failure or malfunction of the products may directly jeopardize human life or potentially cause personal injury (e.g. aircraft and aerospace equipment, traffic and transportation equipment, combustion equipment, medical equipment, accident prevention, anti-crime equipment, and/or safety equipment), it is necessary to verify whether the specifications of our products fit to such applications. Please ensure that you will ask and check with our inquiry desk as to whether the specifications of our products fit to such applications use before you use our products. 

m The quality and performance of our products as described in this online catalog only apply to our products when used in isolation. Therefore, please ensure you evaluate and verify our products under the specific circumstances in which our products are assembled in your own products and in which our products will actually be used. 

m@ If you use our products in equipment that requires a high degree of reliability, regardless of the application, it is recommended that you set up protection circuits and redundancy circuits in order to ensure safety of your equipment. 

m The products and product specifications described in this online catalog are subject to change for improvement without prior notice. Therefore, please be sure to request and confirm the latest product specifications which explain the specifications of our products in detail, before you finalize the design of your applications, purchase, or use our products. 

m@ The technical information in this online catalog provides examples of our products' typical operations and application circuits. We do not guarantee the non-infringement of third party's intellectual property rights and we do not grant any license, right, or interest in our intellectual property. 

m@ If any of our products, product specifications and/or technical information in this online catalog is to be exported or provided to non-residents, the laws and regulations of the exporting country, especially with regard to security and export control, shall be observed. 

<Regarding the Certificate of Compliance with the EU RoHS Directive/REACH Regulations> 

m The switchover date for compliance with the RoHS Directive/REACH Regulations varies depending on the part number or series of our products. 

m When you use the inventory of our products for which it is unclear whether those products are compliant with the RoHS Directive/REACH Regulation, please select "Sales Inquiry" in the website inquiry form and contact us.

**Voltage Step-up Coils** 

## Safety Precautions 

(Common precautions for Voltage Step-up Coils) 

- When using our products, no matter what sort of equipment they might be used for, be sure to make a written agreement on the specifications with us in advance. The design and specifications in this catalog are subject to change without prior notice. 

- Do not use the products beyond the specifications described in this catalog. 

- This catalog explains the quality and performance of the products as individual components. Be fore use, check and evaluate their operations when installed in your products. 

- Install the following systems for a failsafe design to ensure safety if these products are to be used in equip ment where a defect in these products may cause the loss of human life or other significant damage, such as damage to vehicles (au to mo bile, train, vessel), traffic lights, medical equipment, aerospace equipment, elec tric heating ap pli anc es, com bus tion/gas equipment, rotating equipment, and disaster/crime prevention equip ment. 

- ✽ Systems equipped with a protection circuit and a protection device 

- ✽ Systems equipped with a redundant circuit or other system to prevent an unsafe status in the event of a single fault 

## Precautions for use 

## 1. Operation range and environments 

- 1 These products are designed and manufactured for general and stan dard use in general elec tron ic equipment (e.g. AV equipment, home electric ap pli anc es, office equipment, information and com mu ni ca tion equipment) 

- 2 These products are not designed for the use in the following special conditions. Be fore using the products, care ful ly check the effects on their quality and performance, and determine whether or not they can be used. • In liquid, such as water, oil, chemicals, or organic solvent 

   - In direct sunlight, outdoors, or in dust 

   - In salty air or air with a high concentration of corrosive gas, such as Cl2, H2S, NH3, SO2, or NO2 

   - In an environment where these products cause dew condensation 

## 2. Handling 

- 1 Do not bring magnets or magnetized materials close to the product. The influence of their magnetic field can change the inductance value. 

- 2 Do not apply strong mechanical shocks by either dropping or collision with other parts. 

   - Excessive schock can damage the part. 

## 3. Resoldering with a soldering iron 

- 1 Resoldering should be done within 3 seconds by soldering iron, the temperature with 350 °C or less and should be cooling down after ward. Both side of terminals shall be fixed closely to PWB. And terminals shall not be pressed in heating. 

**==> picture [140 x 124] intentionally omitted <==**

**----- Start of picture text -----**<br>
Don’t Press<br>Wiring  Tab<br>**----- End of picture text -----**<br>


- 2 The wiring tab shall not be held by sharp-edged tool. 

- 3 Iron shall not be put to the component itself. 

## 4. Mounting side 

- 1 External force must be less than 4.9N while mounting. 

- 2 The wiring tab is expose the terminal, so please be careful when you design PWB pattern of coil circumference. 

## 5. Cleaning 

If you clean the inductor, please use own your ultrasonic cleaning to check specified conditions. 

## 6. Storage conditions 

Normal temperature (–5 to 35 °C),  normal humidity (85 % RH max.), shall not be exposed to direct sunlight and harmful gases and care should be taken so as not to cause dew. 

<Package markings> 

Package markings include the product number, quantity, and country of origin. In principle, the country of origin should be indicated in English. 

Design and specifications are each subject to change without notice.  Ask factory for the current technical specifications before purchase and/or use. Should a safety concern arise regarding this product, please be sure to contact us immediately.
