Vishay Intertechnology has broadened its 193 PUR‑SI miniature snap‑in power aluminum electrolytic capacitor line to include 550 V and 600 V ratings, extending the series that previously topped out at 500 V. The new parts deliver up to 30 % higher ripple current—up to 3.27 A—than comparable solutions in the same case sizes, and they are rated for 5,000 hours at +105 °C, giving designers a longer useful life.
The expanded series covers capacitances from 47 µF to 820 µF across 25 case sizes ranging from 22 mm × 25 mm to 35 mm × 60 mm. All units are RoHS‑compliant, feature a cylindrical aluminum case with a blue sleeve, and use 3‑pin keyed snap‑in terminals for secure PCB mounting. Production lead times are 18 weeks for quantity orders.
By raising the voltage rating, Vishay enables customers to replace three 400‑450 V capacitors in series with a single higher‑voltage part, eliminating the need for voltage‑balancing resistors and reducing board space and bill‑of‑materials costs. The new parts are targeted at high‑power converters, chargers, battery‑management systems, motor controls in electric and hybrid vehicles, industrial drives, solar inverters, medical equipment, UPS, and welding equipment—markets that are increasingly adopting higher DC bus voltages.
The launch follows a 2022 update that added 570 V and 475 V variants for solar applications, underscoring Vishay’s strategy to support the growing e‑mobility, sustainability, and smart‑grid sectors. The higher‑voltage capacitors strengthen Vishay’s competitive position in the power‑capacitor market, where customers demand higher power density and reliability.
While the announcement is a product‑level milestone, it aligns with Vishay’s broader investment in capacity expansion and advanced technologies such as silicon carbide, positioning the company to capture demand from electric‑vehicle manufacturers and renewable‑energy developers. The new series is expected to contribute to Vishay’s ongoing efforts to improve order intake and support long‑term growth in high‑growth markets.
