AC Line Filters – Common Mode SSR Coils, 21H Series, High Impedance Type 

## **NOT FOR NEW DESIGN** 

## **Handling Precautions** 

## **Precautions for product storage** 

AC Line Filters should be stored in normal working environments. While the chokes themselves are quite robust in other environments, solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long term storage. 

KEMET recommends that maximum storage temperature not exceed 40°C and maximum storage humidity not exceed 70% relative humidity. Atmospheres should be free of chlorine and sulfur bearing compounds. Temperature fluctuations should be minimized to avoid condensation on the parts. Avoid storage near strong magnetic fields, as this might magnetize the product. 

For optimized solderability, AC line filters stock should be used promptly and preferably within 6 months of receipt. 

## **Product temperature rise values** 

The values listed for temperature rise are the result of self-heating in wires when the rated current (commercial frequency) is applied. 

When using the product, check and evaluate the value of the core temperature rise under actual operating conditions. 

## **Export Control** 

## **For customers in Japan** 

For products that are controlled items subject to the “Foreign Exchange and Foreign Trade Law” of Japan, the export license specified by the law is required for export. 

## **For customers outside Japan** 

AC line filters should not be used or sold for the use in the development, production, stockpiling, or utilization of any conventional weapons, mass-destruction weapons (nuclear, chemical, biological weapons, or missiles), or any other weapons.
