14 A Active EMI Filter SIP for 48 Vdc Bus
QPI-6
QUIETPOWER
Description:
The QPI-6 active EMI filter attenuates conducted commonmode (CM) and differential-mode (DM) noise over the CISPR22 frequency range of 150 kHz to 30 MHz. The product is designed for use on 48 Vdc bus (36 – 76 Vdc) systems, with 100 Vdc surge capability. The QPI-6’s 14 A rating supports multiple DC-DC converter loads up to an ambient temperature of 65°C without de-rating. Designed for the telecom and ITE bus range, the QPI-6 supports the PICMG® 3.0 specification for filtering system boards to the EN55022 Class B limits.
In comparison to passive solutions, the use of active filtering reduces the volume of the common-mode choke, providing a low profile, surface mount device.
