The RER40F3740RC02 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, minimizing reactive components. This resistor has a power rating of 5 watts at 25 °C and operates within a resistance range of 374 ohms 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 °C to +250 °C, ensuring reliability in extreme conditions. The insulation resistance is a minimum of 10,000 MΩ when dry, and 1,000 MΩ after moisture testing. The RER40F3740RC02 is suitable for applications requiring high reliability and performance under demanding conditions, making it a viable choice for engineers looking for robust resistor solutions in military or industrial environments.
