Product Overview
The ARCOL HS Aluminium Housed Resistors are designed for direct heatsink mounting to achieve maximum performance, manufactured in line with MIL 18546 and IEC 115 requirements. These resistors offer a high power-to-volume ratio and are wound to maximize high pulse capability. They are suitable for applications requiring robust power dissipation and are RoHS compliant. The series is available in a wide range of ohmic values from R005 to 100K, with custom designs also welcomed. For optimal heat transfer, application of heat sink compound between the resistor base and the heatsink mounting surface is recommended, ensuring the maximum hot spot temperature of 200C is not exceeded.
