Vishay Dale RWR wirewound resistors feature a high temperature silicone coating in a complete welded construction. These resistors are qualified to MIL-PRF-39007. They are available in non-inductive styles (types ESN and EGN) with Ayrton-Perry winding for lowest reactive components. “S” level failure rate is also available.
