14 A Active EMI Filter SIP for 48 Vdc Bus  
Description:  
Features:  
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.  
40 dB CM attenuation at 250 KHz (50Ω)  
80 dB DM attenuation at 250 KHz (50Ω)  
80 Vdc (max input)  
100 Vdc surge 100 ms  
1,500 Vdc hipot hold off to shield plane  
14 A rating  
25.3 x 25.3 x 5.0 mm Lidded SiP (System-in-Package)  
24.9 x 24.9 x 4.4 mm Open-frame SiP  
Low profile LGA package  
-40° to +125°C Ambient temperature (see Figure 12)  
Efficiency >99%  
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.  
Connect in series for higher attenuation
