Not Recommended for New Designs QPI-6 QUIETPOWER 14 A Active EMI Filter SIP for 48 Vdc Bus Description: Features: The QPI-6 active EMI filter attenuates conducted common- 40 dB CM attenuation at 250 KHz (50) mode (CM) and differential-mode (DM) noise over the 80 dB DM attenuation at 250 KHz (50) CISPR22 frequency range of 150 kHz to 30 MHz. The product 80 Vdc (max input) is designed for use on 48 Vdc bus (36 76 Vdc) systems, with 100 Vdc surge 100 ms 100 Vdc surge capability. The QPI-6s 14 A rating supports 1,500 Vdc hipot hold off to shield plane multiple DC-DC converter loads up to an ambient 14 A rating temperature of 65C without de-rating. Designed for the 25.3 x 25.3 x 5.0 mm Lidded SiP (System-in-Package) telecom and ITE bus range, the QPI-6 supports the PICMG 24.9 x 24.9 x 4.4 mm Open-frame SiP 3.0 specification for filtering system boards to the EN55022 Low profile LGA package Class B limits. -40 to +125C Ambient temperature (see Figure 12) Efficiency >99% In comparison to passive solutions, the use of active filtering Connect in series for higher attenuation reduces the volume of the common-mode choke, providing a TV Certified low profile, surface mount device. Smaller size saves valuable board real estate and the reduced height enhances airflow in blade applications. Applications The QPI-6 is available as a lidded or an open-frame SiP ATCA blades (System-in-Package) with Telecom base stations LGA mounting. Evaluation IBA & distributed power boards are available to allow Network switches and routers for quick in-circuit testing of Optical line-cards the QPI-6LZ within an Figure 1 - QPI-6LZ TD-SCMA wireless infrastructure 2 existing system design.
