RFI gaskets specifically target radio frequency interference (typically 30 MHz to 1 GHz), while EMI gaskets cover broader electromagnetic interference including lower frequencies. In practice, the terms are often used interchangeably as most gaskets address both.
Replacement depends on environmental conditions and compression cycles. Typically every 3-5 years or when compression set exceeds 25%, shielding effectiveness drops below specifications, or visible damage occurs.
Yes, many RFI gaskets offer dual functionality providing both electromagnetic shielding and environmental protection against dust, moisture, and liquids when properly compressed.
