CORPUS CHRISTI, Texas, 11 May 2010. Military-qualified thin film chip resistors from IRC Inc. in Corpus Christi, Texas, have received preliminary T-Level qualification from the Defense Supply Center Columbus (DSCC) in Columbus, Ohio, and the devices are listed on the DSCC Qualified Products List (QPL), company officials announced today. IRC is part of TT electronics plc.
IRC is receiving DSCC Class-T qualification and DSCC QPL listing for its PFC Series thin film chip resistors, which are available in 1505, 1206, 0805, and 0603 package sizes.
DSCC T-qualified components are for space applications, and meet special standards for outgassing, 100 thermal shock cycles, 100-percent screening for power conditioning and burn-in, destructive physical analysis, detailed pre-cap inspection, and capability to meet critical performance parameters like resistance noise. DSCC class-T resistors have a maximum failure rate of one-tenth of one percent every 1,000 hours of operation.
"This T-level designation extends the range of IRC's precision thin film chip resistors that can be specified for military/aerospace equipment with the highest reliability requirements, including all space-level applications beyond R and S levels," says Debasis Roy, director of the IRC thin film business unit.
Power rating for the resistors is dependent on chip sizes and MIL-PRF-55342 characteristics. The PFC Series thin film chip resistors are qualified to E, H, K and M characteristics and are available with resistance ranges from 10 Ohms to 125 kilo-Ohms.
