MIL-COTS 20A, 40Vdc Active EMC Filters
The FQB filter modules have been designed to reduce differential and common mode conducted emissions from dc-dc switching converters. In addition, the
series contains active suppression circuitry to block input voltage surges and transients. The FQB takes advantage of TDK technologies to simplify system
level compliance to MIL-STD-461, MIL-STD-1275, RTCA/DO-160 and MIL-STD-704 per MIL-HDBK-704-8. The encapsulated rugged package design and a
choice of baseplate options make the modules suitable for use in a wide variety of harsh and demanding environments, including MIL-COTS.
