FQA and FQB

20A, 40Vdc Demanding Environment EMC Filters

The FQA filter modules reduce differential and common mode conducted emissions from dc-dc switching converters. The series takes advantage of TDK technologies to simplify system level compliance to MILSTD-461. The FQB filter modules reduce conducted emissions from dc-dc switching converters, and in addition, contains active suppression circuitry to block input voltage surges and transients. The FQB series simplifies 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 FQA and FQB modules suitable for use in a wide variety of harsh and demanding environments.
