Vishay Intertechnology, Inc. Chassis Mount Resistors RER50F1R65RC02

The RER50F1R65RC02 is a chassis mount wirewound resistor from Lingto Electronic Limited, designed for military applications and qualified to MIL-PRF-39009 standards. It features an aluminum heat sink housing and a molded construction that provides total environmental protection. The resistor is constructed with complete welded assembly and offers non-inductive styles manufactured using Ayrton-Perry winding, which minimizes reactive components. This specific model has a power rating of 20 watts at 25 ¬8C and operates within a resistance range of 1 to 6.04 kOc with a tolerance of ¬±1%. It is suitable for use in a wide temperature range from -55 ¬8C to +250 ¬8C. The resistor also meets stringent insulation resistance requirements, ensuring reliable performance in various conditions. The construction materials include a copper-nickel or nickel-chrome alloy element, ceramic or steatite core, and an aluminum housing with hard anodic coating. Engineers considering this resistor should note its robust performance specifications, including low temperature operation, short time overload, and moisture resistance, making it suitable for demanding applications.
