Vishay Intertechnology, Inc. Resistor-Misc RER50F5R11PC02

The RER50F5R11PC02 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, which minimizes reactive components. This specific model has a power rating of 20 watts at 25 ¬8C and a resistance value of 5.11 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 resistor also boasts a high insulation resistance of 10,000 MOc minimum when dry and 1,000 MOc minimum after moisture testing. Engineers considering this resistor should note its robust performance under various conditions, including low and high temperature operations, short time overloads, and moisture resistance, making it suitable for demanding applications. The product's construction and specifications suggest it is a reliable choice for projects requiring high-performance resistors in challenging environments.
