New Yorker stocks Vishay Dale’s mission-critical wirewound and metal film resistors
Military and aerospace resistors manufactured by Vishay Dale are available from New Yorker Electronics. Vishay’s -40dB MIL-PRF-55182 ERC (RNC/RNR) and MIL-PRF-39007 RWR with high-temperature silicone coating are mission-critical products from Vishay Dale’s military / aerospace parts division.
Both are hard to acquire, said the distributor, particularly the RNC50, RNC55, RNC60 and RNC65 models. The Vishay Dale mil-spec, axial-lead resistors are designed for the most rigorous environments and are part of New Yorker’s stock of mil-aero products.
The Vishay RWR Type MIL-PRF-39007 qualified axial-lead wirewound resistors are coated with high-temperature silicone and have a welded construction with a failure rate up to Level S (0.001 per cent per 1000h). The series is available in non-inductive styles (type N) with Ayrton-Perry winding for low reactive components. Tolerances are ± 0.1, ± 0.5 and ± 1.0 per cent with resistance values from 49.9 to 1000W. Vishay RWRs are also available in terminal wire / winding options of solderable / inductive, solderable / non-inductive, weldable / inductive and weldable / non-inductive.
The Vishay ERC (Military RNC/RNR) series of high-precision metal film resistors are MIL-PRF-55182 qualified. They have undergone 100 per cent stabilisation and screening tests. The Vishay RNC (solderable / weldable) and RNR (solderable only) devices have a controlled temperature co-efficient with an epoxy coating to provide superior moisture protection. The ERC also has tolerances of ± 0.1, ± 0.5 and ± 1.0 per cent with resistance values with a failure rate up to Level S.
Vishay ERC resistors are available in voltage ratings from 200 to 350V DC and resistance ranges between 10 to 796k and 10 to 3.01M. Low noise rating is -40dB. The standard lead on the Vishay RNC is solderable and weldable.
The devices receive monthly acceptance testing. Additionally, Vishay Dale can develop specific reliability programs designed to customer requirements.
New Yorker Electronics supplies Vishay Dale discrete semiconductors (diodes, MOSFETs and infrared optoelectronics) and passive electronic components (resistors, inductors and capacitors).
