Vishay Intertechnology Adds Pick-and-Place Friendly Lead Bending Option for Cemented, Axial-Leaded Wirewound Resistors
Allows Devices to Be Used as SMD Components to Reduce Assembly Costs
MALVERN, Pa., Oct. 12, 2022 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today announced that certain devices in its 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, the Vishay Draloric resistors are the industry’s first such devices to be offered in a non-inductive version. The devices available with the WSZ lead form are shown in the table below.
| Device | P40 power dissipation rating | Resistance range | Resistance tolerance |
| AC03 WSZ | 3 W | 0.10 Ω to 5.1 kΩ | ± 5 % |
| AC03-AT WSZ* | 3 W | 0.27 Ω to 3.3 kΩ | ± 5 % |
*AEC-Q200 qualified
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. The devices will serve as snubber, load, and inrush current limiting resistors for pre-charge / discharge applications in automotive and industrial electronics, energy meters, and white goods power supplies.
For challenging operating conditions, the devices 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, thermal shocks, dielectric strength, and insulation resistance 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 series resistors with WSZ lead forms are available now, with lead times of 16 weeks.
