Picor Corporation Active Input EMI Filter QPI-4LZ

Description The QPI-4 active EMI filter attenuates conducted common-mode (CM) and differential-mode (DM) noise over the CISPR22 frequency range of 150 kHz to 30 MHz. The product is designed for use on a 48 Vdc bus (36 – 76 Vdc).The QPI-4's 7 A rating supports multiple DC-DC converter loads up to a PCB temperature of 60°C. At a 100°C PCB temperature the QPI-4 supports 6 A loads. Designed for the telecom and ITE bus range, the QPI-4 supports the PICMG® 3.0 specification for filtering system boards to the EN55022 Class B limits.
