- Install the following systems for a failsafe design to ensure safety if these products are to be used in equipment where a defect in these products may cause the loss of human life or other significant damage, such as damage to vehicles (automobile, train, vessel), traffic lights, medical equipment, aerospace equipment, electric heating appliances, combustion/gas equipment, rotating equipment, and disaster/crime prevention equipment. 

   - ✽ 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. 

   - ✽ Systems equipped with an arresting the spread of fire or preventing glitch. 

## **Precautions for use** 

- These products are designed and manufactured for general and standard use in general electronic equipment. (e.g. AV equipment, home electric appliances, office equipment, information and communication equipment) For applications in which special quality and reliability are required, or if the failure or malfunction of the products may directly jeopardize life or cause threat of personal injury (such as for aircraft and aerospace equipment, traffic and transport equipment, combustion equipment, medical equipment, accident prevention and anti-theft devices, and safety equipment), please be sure to consult with our sales representative in advance and to exchange product specifications which conform to such applications. 

- These products are not intended for use in the following special conditions. Before using the products, carefully check the effects on their quality and performance, and determine whether or not they can be used. 

   1. In liquid, such as water, oil, chemicals, or organic solvent. 

   2. In direct sunlight, outdoors, or in dust. 

   3. In salty air or air with a high concentration of corrosive gas, such as Cl2，H2S，NH3，SO2，or NOX . 

   4. Electric Static Discharge (ESD) Environment. 

      - These components are sensitive to static electricity and can be damaged under static shock (ESD). 

      - Please take measures to avoid any of these environments. 

      - Smaller components are more sensitive to ESD environment. 

   5. Electromagnetic and Radioactive Environment. 

      - Avoid any environment where strong electromagnetic waves and radiation exist. 

   6. In an environment where these products cause dew condensation. 

   7. Sealing or coating of these products or a printed circuit board on which these products are mounted, with resin or other materials. 

- These products generate Joule heat when energized. Carefully position these products so that their heat will not affect the other components. 

- Carefully position these products so that their temperatures will not exceed the category temperature range due to the effects of neighboring heat-generating components.  Do not mount or place heat-generating components or inflammables, such as vinyl-coated wires, near these products. 

- Note that non-cleaning solder, halogen-based highly active flux, or water-soluble flux may deteriorate the performance or reliability of the products. 

- Carefully select a flux cleaning agent for use after soldering. An unsuitable agent may deteriorate the performance or reliability. In particular, when using water or a water-soluble cleaning agent, be careful not to leave water residues. Otherwise, the insulation performance may be deteriorated. 

- Do not apply flux to these products after soldering.  The activity of flux may be a cause of failures in these products. 

- Refer to the recommended soldering conditions and set the soldering condition.  High peak temperature or long heating time may impair the performance or the reliability of these products.

**Common Mode Noise Filters** 

- Recommended soldering condition is for the guideline for ensuring the basic characteristics of the products, not for the stable soldering conditions. Conditions for proper soldering should be set up according to individual conditions. 

- Do not reuse any products after removal from mounting boards. 

- Do not drop these products.  If these products are dropped, do not use them.  Such products may have received mechanical or electrical damage. 

- If any doubt or concern to the safety on these products arise, make sure to inform us immediately and conduct technical examinations at your side. 

## **Precautions for storage** 

The performance of these products, including the solderability, is guaranteed for a year from the date of arrival at your company, provided that they remain packed as they were when delivered and stored at a temperature of  -5 °C to +40 °C and a relative humidity of 15 % to 75 %. 

Even within the above guarantee periods, do not store these products in the following conditions. Otherwise, their electrical performance and/or solderability may be deteriorated, and the packaging materials (e.g. taping materials) may be deformed or deteriorated, resulting in mounting failures. 

1. In salty air or in air with a high concentration of corrosive gas, such as Cl2，H2S，NH3，SO2，or NOX . 

2. In direct sunlight. 

## ＜Package markings＞ 

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

## **Precaution specific to this product** 

1. Use rosin-based ux or halogen-free ux. 

2. For cleaning, use an alcohol-based cleaning agent. Before using any other type, consult with our sales person in advance. 

3. Mounting of the suppressors with excessive or insufficient wetting amount of solder may affect the connection reliability or the performance of the suppressors.  Carefully check the effects and apply a proper amount of solder for use. 

4. Do not apply shock to Filters or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, their bodies may be chipped, affecting their performance. Excessive mechanical stress may damage the filters. Handle with care. 

7. Avoid excessive bending of printed circuit boards in order to protect the suppressors from abnormal stress. 

8. Do not immerse the suppressors in solvent for a long time. Before using solvent, carefully check the effects of immersion. 

9. Do not apply excessive tension to the terminals.
