Vishay Intertechnology, Inc. Chassis Mount Resistors RER55F80R6RC02

The RER55F80R6RC02 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 techniques and offers non-inductive styles manufactured using Ayrton-Perry winding, minimizing reactive components. This specific model has a power rating of 30 watts at 25 ¬8C and operates within a resistance range of 1 to 4.99 kOc, with a tolerance of ¬±1%. It is capable of withstanding operating temperatures from -55 ¬8C to +250 ¬8C. The resistor also meets stringent performance criteria, including low temperature operation, short time overload, and moisture resistance, ensuring reliability in demanding environments. The encapsulant is made of silicone, and the housing is finished with a hard anodic coating for durability. Engineers considering this resistor should note its robust construction and military-grade specifications, making it suitable for applications requiring high reliability and performance under extreme conditions.
