MQPI-18LP

Active Input EMI Filter with High CM and DM Attenuation for MIL Applications

Description

The MQPI-18LP is a surface mount, DC front-end filter that provides EMI filtering for Vicor’s 28 V MIL-COTS DC-DC V•I Chip or VI BRICK modules. MQPI-18LP enables designers to meet conducted emission / conducted susceptibility per MIL-STD-461E. The MQPI-18LP accepts an input voltage of 10 – 50 Vdc and delivers output current up to 7 Amp. MQPI-18LP is housed in a very compact 0.98″ x 0.49″ x 0.18″ package requiring only 0.5 in2 of board space and weighing only 2.4 grams.
