Additional Details

The FPA600-150R-J has a resistance tolerance that is typically 5%. It is crucial to mount the resistor on an appropriate heat sink to achieve its rated power dissipation. Proper heat sink selection depends on the ambient temperature and the amount of power being dissipated. Detailed derating curves are often available in the product datasheet. The resistor is designed for operation within a specified temperature range. This resistor is often bolted directly to a chassis or other metal surface for heat sinking.
