Vishay Intertechnology, Inc. Chassis Mount Resistors RER65F4421PC02

The RER65F4421PC02 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 joints and offers non-inductive styles manufactured using Ayrton-Perry winding, which minimizes reactive components. With a power rating of 10 watts at 25 ¬8C, the RER65F4421PC02 has a resistance value of 4.42 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 high insulation resistance, rated at a minimum of 10,000 MOc when dry, and meets solderability requirements per ANSI J-STD-002. Engineers considering this resistor can expect reliable performance under various conditions, including low and high temperature exposure, moisture resistance, and mechanical stress tests, making it suitable for demanding applications.
