MQPI-18
28 Volt Input, 7 Amp MIL COTS EMI Filter for Vâ¢I Chips
Description
The MQPI-18 attenuates conducted common-mode
(CM) and differential mode (DM) noise for 28 V input
MIL PRMs to comply with MIL-461E EMI requirements
for conducted noise measurements. The filter operates
within the full input operating range of a 28 V MIL
PRM and supports 7 A loads up to 60°C without
derating.
Features
⢠28 V input, compatible with MIL PRM
⢠MIL-STD-461E compliant* CE101, CE102, CS101,
CS114, C5115, and CS116
⢠100 Vdc surge, 100 ms
⢠1,500 Vdc hi-pot hold off to shield plane
⢠7 A rating
⢠Efficiency >99%
⢠Low profile LGA package
⢠-55°C to 100°C operation (PCB Temp.)
⢠Pb solder construction
Typical Applications
⢠Military mobile and fixed communications
⢠Radar and Targeting
⢠Missile and Launch systems
⢠Airborne flight management systems
Assembly process compatibility
⢠Intended for Pb solder SMT assembly
⢠Compatible with typical aqueous cleaning
processes (open-frame only)
⢠Compatible with most conformal coating
compounds [after reflow] (open frame only).
12.9 x 25.3 x 5 mm
Weight = 2.4 grams
