Vishay Intertechnology, Inc. Chassis Mount Resistors RER70F2000MC02

The RER70F2000MC02 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 is available in non-inductive styles, utilizing Ayrton-Perry winding to minimize 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 a wide operating temperature range of -55 ¬8C to +250 ¬8C. The resistor's insulation resistance is a minimum of 10,000 MOc when dry, and it meets solderability requirements as per ANSI J-STD-002. The construction materials include a copper-nickel or nickel-chrome alloy element, ceramic or steatite core, and an aluminum housing with hard anodic coating. Engineers considering this resistor should note its robust performance under various environmental conditions, including low and high temperature exposure, moisture resistance, and vibration. The RER70F2000MC02 is ideal for applications requiring high reliability and durability.
