 QPI-4LZ
7 Amp Active EMI Filter for 48 V DC Bus
|
|
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. |
