QPI-5LZ
14 Amp Active EMI Filter for 24 V DC Bus
QPI-5LZ

Product Resources
 The QPI-5 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 a 24 Vdc bus (10-40 Vdc). The QPI-5’s 14 A rating supports multiple DC-DC converter loads up to a PCB temperature of 60°C. At a 100°C PCB temperature the QPI-5 supports 12 A loads. Designed for a nominal 24 V bus, the QPI-5 supports industrial and COTS applications.
