25W 4R7 is a Power wire wound resistor it can have wire of power oxide film elements. Its entirely fire proof constructions. This design provides a resistor with high insulation resistance and low surface temperature. These resistors are ideally suited to a range of areas where low cost, and efficient thermal performance are important design criteria. Metal film cores adjusted by laser spiral are used where the resistor value is above that suited to wire.
- Its value range is too wide
- Its operating temperature is -55 to 250 Degree centigrade
- Its construction is inorganic flame proof
- Its color is white
|Type||Wire wound Resistor|
