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.
