The robust design and wide operating temperature range make these resistors ideal for automotive, industrial electronics, and power supply applications.
Vishay Intertechnology, Inc has unveiled that 5 W devices in its AC and AC-AT series of cemented, axial-leaded wirewound resistors now feature a pick-and-place-friendly SMD lead bending option, the WSZ lead form, which transforms these devices into surface-mount components. The Draloric AC05 WSZ and AEC-Q200 qualified AC05-AT WSZ resistors, also available in a non-inductive version (AC05-NI WSZ), are designed for fast-switching circuits and exhibit excellent pulse capability.
The key features include:
- Peak power up to 5 kW for a 1 μs pulse load
- Broad resistance range from 0.10 Ω to 10 kΩ
- Operating temperature range from -55 °C to +250 °C
- Wirewound construction for high mechanical resistance
- Thermal shock resilience at elevated temperatures
The WSZ lead form enables these resistors to be assembled on PCBs alongside other surface-mount components, enhancing the pick-and-place process, reducing assembly times, and lowering costs. These devices are ideal for use as snubber and inrush current limiting resistors in pre-charge/discharge applications across automotive and industrial electronics, energy meters, and power supplies for white goods.
Engineered for challenging operating conditions, the AC05 WSZ and AC05-AT WSZ feature a robust, non-flammable silicone cement coating that meets UL 94 V-0 standards. These RoHS-compliant, halogen-free devices come with tin-plated terminations, ensuring compatibility with both lead (Pb)-free and lead (Pb)-containing soldering processes. Samples and production quantities of the AC05 WSZ and AC05-AT WSZ are currently available, with lead times set at 12 weeks.
