Vishay Intertechnology, Inc. Chassis Mount Resistors RER70F1000MCSL

The RER70F1000MCSL 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 using complete welded techniques and offers non-inductive styles manufactured with Ayrton-Perry winding to minimize reactive components. This model has a power rating of 20 watts at 25 ¬8C and a resistance value of 1000 ohms with 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, and 1,000 MOc after moisture testing. The resistor is suitable for applications requiring high reliability and performance under extreme conditions.
