The RER45F37R4RCSL 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 specific model has a power rating of 10 watts at 25 °C and a resistance value of 37.4 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, making it a viable option for engineers looking for robust components in demanding environments.
