TTElectronics - Welwyn WMHP3547RF High Power Resistor

The Welwyn WMHP series consists of high-power, through-hole mount resistors designed for high-temperature and high-power applications. These resistors are available in various case styles, including WMHP20, WMHP35, WMHP50 (TO-220), and WMHP100 (TO-247). They offer resistance values from 0.05 ohms to 10 kΩ, covering E24 decade values. Power ratings range from 20W (without heatsink) to 100W (with heatsink). They feature tolerance levels of ±1% or ±5%, with operating temperatures spanning from -65°C to 175°C. The temperature coefficient of resistance varies up to ±1000ppm/°C. Key electrical specifications include a dielectric strength of 1800V, insulation resistance over 10 GΩ, limiting element voltages of 350V for the smaller models and 700V for the largest. These resistors are suitable for demanding high-power applications requiring reliable performance and thermal stability.
