EMI/RFI Filter and Capacitor Performance Testing

The resin sealed and hermetically sealed filters shown in this table have been designed to meet the requirements of this test plan as applicable.  Group I tests are typically performed on most product.  Groups II, III, and IV tests are performed per specification requirements.

The information shown can be used as a basis for filter specifications.  Contact us directly for additional details if necessary.
