Characteristics - Electrical
Derating Curve Pulse Energy THS10 to THS75 Surface Temperature Rise
The THS is a range of extremely stable, high quality wire-wound resistors capable
of dissipating high power in a limited space with relatively low surface temperature.
The power is rapidly dissipated as heat through the aluminium housing to a
specified heatsink. The resistors are made from quality materials for optimum
reliability and stability. TE Connectivity can test resistors to conform to relevant
international, MIL or customer specifications.
