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.

Note 1: CB1 capacitor, referenced in all schematics, is a 47uF electrolytic; United Chemi-Con EMVE101ARA470MKE0S or equivalent.
CY1 to CY4, referenced in all schematics, are 4.7nF hi-voltage safety capacitors; Vishay VY1472M63Y5UQ63V0 or equivalent.
CIN is the manufacturer’s recommended value for input capacitor.

Figure 7 - Base-plate EMI test setup using the QPI-6-CB1 carrier board with 48V converter.
In Figures 6 and 7, C1 is the required 47uF capacitor (United
Chemi-Con EMVE101ARA470MKE0S or equivalent), C2 is a
converter input cap (value dependant on converter), and CY
caps are 4.7nF ceramic (Murata GRM31BR73A472KW01L or
equivalent).
Attenuation Plots: Converters in base-plate and open-frame configurations, tested as shown in Figure 7.
