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 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, 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.
