Vishay Intertechnology, Inc. Chassis Mount Resistors RER50F2R74RC02

The RER50F2R74RC02 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 using Ayrton-Perry winding to minimize reactive components. This model has a power rating of 20 watts at 25 °C and operates within a resistance range of 1 to 6.04 kΩ, with a tolerance of ±1%. It is suitable for use in a wide temperature range from -55 °C to +250 °C. The resistor's insulation resistance is a minimum of 10,000 MΩ when dry, and it meets solderability requirements as per ANSI J-STD-002. The RER50F2R74RC02 is designed to mount on a chassis to utilize the heat-sink effect, making it ideal for applications requiring reliable thermal management.
