Vishay Intertechnology, Inc. Chassis Mount Resistors RER70F8R25RC02

The RER70F8R25RC02 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 0.1 to 12.1 kOc, with a tolerance of ¬±1%. It is capable of withstanding a maximum working voltage determined by the formula (P x R)^{1/2}. The operating temperature range is from -55 ¬8C to +250 ¬8C, ensuring reliability in extreme conditions. The RER70F8R25RC02 is suitable for applications requiring high reliability and performance, making it a viable option for engineers looking for robust resistive components in demanding environments.
