RS PRO 100W Aluminium Wirewound Resistors, 20Ω
An Aluminium housed resistor with a resistance of 20Ω designed for direct heatsink mounting, using a thermal compound to achieve maximum performance.
A highly stable resistor with a high power to volume ratio and a wirewound design to maximise high pulse capability. At only 88mm in length the Aluminium resistor is compact compared to its power rating of 100W.
Manufactured to MIL 18546 and IEC 115 specifications the wirewound resistor is suitable for industrial and military applications and its compact size make it ideal for installation where space is restricted.
