AC Line Filters – Differential Mode SN Coils, Standard Series
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.
