Vishay Intertechnology, Inc. Chassis Mount Resistors RER70F5621RCSL

The RER70F5621RCSL 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 20 watts at 25 ¬8C, the RER70F5621RCSL has a resistance value of 5.62 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 resistor also boasts a high insulation resistance of 10,000 MOc minimum when dry, ensuring reliability in various conditions. This component is suitable for applications requiring robust performance and reliability, particularly in military and high-stress environments. Its design allows for effective heat dissipation when mounted on a chassis, making it a viable option for engineers seeking durable and efficient resistive solutions.
