14 A Active EMI Filter SIP for 48 Vdc Bus
QPI-6
QUIETPOWER^
Description:
The QPI-6 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 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. Smaller size saves valuable
board real estate and the reduced height enhances airflow in
blade applications.
The QPI-6 is available as a
lidded or an open-frame SiP
(System-in-Package) with
LGA mounting. Evaluation
boards are available to allow
for quick in-circuit testing of
the QPI-6LZ within an
existing system design.
