Vishay Intertechnology Adds Pick and Place Friendly SMD Lead Bending Option for AC05 and AC05-AT 5 W Cemented, Axial-Leaded Wirewound Resistors

WSZ Lead Form Allows Devices to Be Used as SMD Components to Reduce Assembly Costs

MALVERN, Pa. — May 29, 2024 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced that 5 W devices in its AC and AC-AT series of cemented, axial-leaded wirewound resistors are now available with a pick and place friendly SMD lead bending option, the WSZ lead form, that allows the devices to be used as surface-mount components. Offering excellent pulse capability, the Vishay Draloric AC05 WSZ and AEC-Q200 qualified AC05-AT WSZ are also offered in a non-inductive version AC05-NI WSZ for fast switching circuits.

Resistors with the WSZ lead form can be assembled on the PCB alongside other surface-mount components to improve the pick and place process, reduce assembly times, and lower costs. The devices will serve as snubber and inrush current limiting resistors for pre-charge / discharge applications in automotive and industrial electronics, energy meters, and white goods power supplies. For these applications, the resistors offer peak power up to 5 kW for a 1 μs pulse load and a broad range of resistance values from 0.10 Ω to 10 kΩ.

For challenging operating conditions, the AC05 WSZ and AC05-AT WSZ feature a robust, non-flammable silicone cement coating that conforms to UL 94 V-0. The resistors operate over a wide temperature range of -55 °C to +250 °C and offer a wirewound construction that meets the highest requirements against mechanical resistance and thermal shocks at high temperatures.

The RoHS-compliant, halogen-free devices offer tin-plated terminations for compatibility with lead (Pb)-free and lead (Pb)-containing soldering processes.

Samples and production quantities of the AC05 WSZ and AC05-AT WSZ are available now, with lead times of 12 weeks.
