Vishay Extends Aluminum Capacitors Rating Up to 600 V for DC Links
ECOMAL Netherlands – 15 June 2026
The extended VISHAY 193 PUR-SI series is part of the BCcomponents aluminum electrolytic capacitor family, optimized for compact, high-ripple DC-link use. The latest variants add 550 V and 600 V rated voltages on top of the existing lower voltage range.
Key technical features include:
- Rated voltages up to 600 V for use on high-voltage DC buses.
- Ripple current capability up to 3.27 A (RMS) at 100 Hz and +105 °C, typically 10% to 30% higher than standard snap-in capacitors in similar case sizes.
- Useful life of 5000 hours at +105 °C, supporting design targets of more than 25 years' operation at ambient temperatures up to around +60 °C in many applications.
- Available in multiple miniature snap-in case sizes, with diameters from roughly 22 mm to 35 mm and lengths from around 25 mm to 60 mm according to the manufacturer datasheet.
- Optional 3-pin keyed polarity snap-in terminal configuration for more stable PCB mounting and reduced risk of incorrect insertion.
