Vishay 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 W to 10 kW.
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.
