Cemented Leaded Wirewound Resistors with High Power Dissipation and Excellent Pulse Load Capability Designed for Automotive and Industrial Electronics

13 October 2022 - 0 Comments

Vishay Intertechnology, Inc. has announced that certain devices in its AC and AC-AT series of cemented, axial-leaded wirewound resistors are now available with a pick-and-place friendly lead bending option, the WSZ lead form, that allows the devices to be used as surface-mount components. Offering high power dissipation and excellent pulse capability, these Draloric resistors are the industry’s first such devices to be offered in a non-inductive version. These resistors with the WSZ lead form can be assembled on the PCB alongside other surface-mount components to improve the pick-and-place process and lower costs. These devices will serve as a snubber, load, and inrush current limiting resistors for pre-charge / discharge applications in automotive and industrial electronics, energy meters, and white goods power supplies.

These resistors feature a robust, non-flammable silicone cement coating that conforms to UL 94 V-0 and operates over a wide temperature range of -55°C to +250°C. These devices offer a wirewound construction that meets the highest requirements against mechanical resistance, thermal shocks, dielectric strength, and insulation resistance at high temperatures. Moreover, they offer tin-plated terminations for compatibility with lead (Pb)-free and lead (Pb)-containing soldering processes.
