The RER70F7R87RCSL 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 °C and a resistance value of 7.87 ohms with a tolerance of ±1%. It operates effectively within a temperature range of -55 °C to +250 °C and has a maximum working voltage determined by the formula (P x R)^{1/2}. The insulation resistance is rated at a minimum of 10,000 MΩ when dry and 1,000 MΩ after moisture testing. The resistor is suitable for applications requiring high reliability and performance under extreme conditions.
