TTElectronics - Welwyn WDBR147RKT Power Resistor
The Welwyn WDBR1 Series are ultra-low profile thick film power resistors designed for high-power applications such as dynamic braking, inrush limiting, and snubber circuits. These resistors feature a single fixing heat sink mount, with terminal options including solder pads, flying leads, and push-on connectors. They offer low inductance and high isolation, maintaining performance even after failsafe overload fusing. Resistance values range from 12 to 150 ohms, with rated powers from 500W up to 7kW, and a pulse power rating of 1.5kW. The power rating on heat sinks is 180W, with an operating temperature of 365°C and a temperature coefficient (TCR) range from +500 to +600 ppm/°C. The resistors are available in 10% tolerance versions, offering high power handling suitable for demanding electrical environments.
