The QPI-3 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 24 Vdc bus (10 – 40 Vdc).
The QPI-3’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-3 supports 6 A loads. Designed for the telecom and ITE bus range, the QPI-3 supports the PICMG® 3.0 specification for filtering system boards to the EN55022 Class B limits.
