WDBR & WDBR-UL Ultra-Low-Profile Power Resistors

TT Electronics WDBR and WDBR-UL Ultra-Low-Profile Power Resistors are ideal for dynamic braking, inrush limit, and snubber circuits. These resistors offer up to 7kW peak power, a low inductance design, and high isolation, even after failsafe overload fusing. The RoHS-compliant, non-flammable construction features a high integrity dielectric layer applied to a machined stainless steel substrate. Thick-film conductor and resistor patterns are printed, fired, and protected with a high-temperature overglaze. The termination pads include tinned with solder and optional terminals or soldered-on leads. TT Electronics WDBR and WDBR-UL Ultra-Low-Profile Power Resistors are single fixing heatsink mountable, and the WDBR-UL series is UL 508 certified.
