The RER75F1211RC02 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. This resistor is constructed with complete welded assembly and offers non-inductive styles manufactured using Ayrton-Perry winding, which minimizes reactive components. With a power rating of 30W at 25¬8C, the resistor has a resistance value of 1.21 kOc and a tolerance of ¬±1%. It operates effectively within a temperature range of -55¬8C to +250¬8C 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 MOc when dry, decreasing to 1,000 MOc after moisture testing. The resistor is suitable for applications requiring high reliability and performance under extreme conditions.
