MIL-COTS EMC filters aimed at use in demanding airborne, vehicle applications
SAN DIEGO, Calif. TDK Corporation has launched its TDK-Lambda FQB series of EMC filters, with a rating of 40Vdc at 20A. Voltage surge and spike protection for DC-DC converters is accomplished through the use of active technology. The FQB has a rugged encapsulated quarter-brick package with a choice of flanged or non-flanged baseplates. These modules are suitable for use in a wide variety of harsh and demanding environments, including MIL-COTS vehicle and airborne applications.
The FQB series is designed with a high differential and common mode noise attenuation, simplifying system level compliance to the MIL-STD-461(F, G) standard. The modules also provide input spike and surge protection per MIL-STD-1275(D, E) and RTCA/DO-160G (Sec 16-18). Qualifying testing is consistent with MIL-STD-883F and MIL-STD-202G. The operating input voltage is 8.5 (start-up) to 40Vdc and the filters can withstand transients of up to -50 to +210V. The filter modules have a remote on-off function and an open collector DC Good/Fault signal.
All models have been safety certified to UL 60950-1, CAN/CSA C22.2 No. 60950-1-07 and IEC 60950-1, and IEC/UL/CSA 62368-1 (pending).
