Caddock MP930 Kool-Pak® power resistor series is part of their MP900 family. These resistors offer heat sink mountable design utilising exposed ceramic heat dissipating mounting surface, custom resistance values in the range between 0.02Ω and 4.99kΩ and tolerance options of ±1.0% (applicable to resistance values above 0.05Ω), ±5.0% or ±20.0%, all in a standard TO-220 through-hole package. The list of standard resistance values, often available from stock, is available on the datasheet. The MP930 series features power rating of up to 30W at +25°C (case temperature derated to zero at +150°C), non-inductive design and are suitable for operation in temperatures of up to 150°C. These resistors are made utilising Caddock’s own Micronox® resistance film fired onto a flat ceramic surface.
