New Yorker Electronics, Co., Inc., announced the expansion of its ready-to-ship inventory of Vishay Dale (Military M/D55342) RCWPM thick film, and E/H thin film surface-mount resistor series. The QPL MIL-PRF-55342 chips are widely specified for employment in the broadest range of mission-critical military, aerospace, weapons systems, satellite, handheld communications, and any military/non-military design in which space is limited. Vishay’s high reliability RCWPM thick film, and E/H thin film resistors, together with multiple lines of Vishay resistors are now available from New Yorker Electronics.
Vishay Dale E/H thin film series of MIL-PRF-55342-qualified SMT resistors’ wraparound termination features a robust adhesion layer covered by an electroplated nickel barrier level to support +150 ºC operating conditions, superior dimensional uniformity, and failure rate. The QPL devices are offered in case sizes from 0402 to 2512, and in voltages from 30V to 200V. Parts have a < -25 dB, 0.5 ppm/V low noise and voltage coefficient. They further provide less than 0.010 Ω typical wraparound resistance and laser-trimmed tolerances down to ±0.1%. E/H thin film chips meet vacuum stability and outgassing requirements of the ASTM E595 standard.
Additionally stocked by New Yorker Electronics are Vishay Dale RCWPM thick film SMT resistors conforming to the MIL-PRF-55342, Type RM specification. Components feature a robust adhesion layer covered by an electroplated nickel barrier plus a verified failure rate at M, P, R, U, S, V, and T levels. These QPL parts are available in case sizes ranging from 0302 to 2512, and in voltages from 30V to 200V. They have an operating temperature range of -65 ºC to +150 ºC along with power ratings from 0.04 W to 1.0 W. Resistors are subject to in-process inspections and Group A lot acceptance testing. Chips are provided intermination style B pre-tinned nickel wraparound barrier and comply with the ASTM B 809-95 standard test method for porosity in metallic coatings by humid sulfur vapor.
