Vishay Intertechnology, Inc. Chassis Mount Resistors RER45F2050RCSL

The RER45F2050RCSL 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 ¬8C and a resistance value of 205 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 RER45F2050RCSL is suitable for applications requiring high reliability and performance under extreme conditions, making it a viable option for engineers looking for robust resistor solutions in demanding environments.
