Vishay Intertechnology, Inc. RES 23.2 OHM 20W 1% AXIAL LUGS RER70F23R2RC02

The RER70F23R2RC02 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 model has a power rating of 20 watts at 25 ¬8C and operates within a resistance range of 0.1 to 12.1K ohms, with a tolerance of ¬±1%. It is suitable for use in a wide temperature range from -55 ¬8C to +250 ¬8C. The resistor also meets stringent performance criteria, including low temperature operation, short time overload, and moisture resistance, ensuring reliability in demanding environments. The encapsulant is made of silicone, and the housing is coated with hard anodic aluminum for durability. Engineers considering this resistor should evaluate its specifications against their project requirements, particularly in terms of power handling, environmental conditions, and compliance with military standards.
