QPI-21LZ-01

The Vicor QPI-21LZ-01 is an active EMI input module designed for 48Vdc bus systems, operating within a 36-76 Vdc range with 100 Vdc surge capability. This filter effectively attenuates conducted common-mode (CM) and differential-mode (DM) noise across the CISPR22 frequency range of 150 kHz to 30 MHz.

With a 14A rating, the QPI-21LZ supports multiple DC-DC converter loads up to an ambient temperature of 65°C without de-rating. It provides significant attenuation, including 45 dB CM and 80 dB DM at 250 KHz. The module is designed for telecom and ITE bus applications and supports the PICMG® 3.0 specification for filtering system boards to EN55022 Class B limits.

Compared to passive solutions, the active filtering technology reduces component size, leading to a smaller overall package. The QPI-21LZ is available in an open-frame SiP (System-in-Package) module with an LGA mounting type. It operates across a wide ambient temperature range of -40°C to +125°C and boasts an efficiency greater than 99%.

This module is cTÜVus approved to UL/CSA 60950-1 and EN 60950-1 standards and is CE marked to the LVD and RoHS Recast Directive as applicable. Typical applications include ATCA blades, telecom base stations, and network switches.
