Descriptions


SP, with the inner and outer surfaces coated with a special glass, features higher thermal resistance and larger electric power capacity for the compact volume. Unlike conventional wire wound resistors, the volumetric resistor will provide superior stability versus frequency and higher durability against transient voltage. Further, SP can be water cooled, which enables the resistor to be suitable for the application with large current as well as high frequency circuit.
