Vishay Intertechnology, Inc. Chassis Mount Resistors RER75F4R64RC02

The RER75F4R64RC02 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 joints and offers non-inductive styles manufactured using Ayrton-Perry winding, which minimizes reactive components. This model has a power rating of 30 watts at 25 ¬8C and operates within a resistance range of 0.1 to 39.2 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 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 product should note its robust construction and military-grade specifications, making it suitable for applications requiring high reliability and performance.
