New Yorker Electronics features two mission-critical products from its defence/aerospace parts division: Vishay’s -40dB MIL-PRF-55182 ERC (RNC/RNR) and MIL-PRF-39007 RWR provides a high-temperature silicone coating.
Created for the most severe environments, the hard-to-acquire Vishay Dale mil-spec, axial-lead resistors are part of the company's comprehensive stock of defence and aerospace offerings, particularly in the case of the RNC50, RNC55, RNC60 and RNC65 models. Further, Vishay Dale offers complete capability to create specific reliability programs developed to customer needs.
The RWR Type MIL-PRF-39007 Qualified Axial-Lead Wirewound Resistors are high-temperature silicone coated with complete welded construction with a failure rate up to Level S (0.001%/1000h). The series is offered in non-inductive styles (type N) with Ayrton-Perry winding for lowest reactive components and are supplied in tolerances of ±0.1%, ± 0.5% and ±1% with resistance values from 49.9W to 1000W. The RWRs are also provided in terminal wire/winding options of solderable/inductive, Solderable/non-inductive, weldable/inductive and weldable/non-inductive.
The ERC (Defence RNC/RNR) series of High-Precision Metal Film Resistors are MIL-PRF-55182 Qualified and has displayed 100% stabilisation and screening tests. The RNC (solderable/weldable) and RNR (solderable only) devices supply a controlled temperature coefficient with an epoxy coating to provide superior moisture protection. Like the RWR, the ERC series is offered in tolerances of ±0.1%, ±0.5% and ±1% with resistance values with a failure rate up to Level S.
The ERC Resistors are provided in voltage ratings from 200VDC to 350VDC and resistance ranges between 10K to 796K and 10M to 3.01M. It keeps a low noise rating of -40dB. The standard lead on the RNC is solderable and weldable. These mission-critical devices receive monthly acceptance testing.
