Vishay Intertechnology Extends 193 PUR-SI Series of Snap-in Power Aluminum Capacitors With Voltage Ratings of 550 V and 600 V
MWN-AI** Summary
Vishay Intertechnology, Inc. (NYSE: VSH) has announced an exciting expansion of its 193 PUR-SI series, introducing new voltage ratings of 550 V and 600 V for its miniature snap-in power aluminum electrolytic capacitors. These advanced components provide designers with significant benefits, including up to 30% higher ripple current capacity compared to standard solutions in similar sizes alongside enhanced longevity.
Historically, engineers often resorted to using three 400 V to 450 V capacitors wired in series, with voltage balancing resistors, to manage DC bus voltages reaching up to 1100 V. This method complicates design and introduces several potential failure points. The new 193 PUR-SI devices simplify this process by enabling designers to handle higher voltage ranges with fewer components, thus eliminating the necessity for voltage balancing circuits. This innovation not only maximizes PCB space but also reduces bill of materials (BOM) costs, while providing the additional voltage headroom that contributes to increased capacitor lifetimes and improved system reliability.
These capacitors are engineered to withstand high switching currents seen in modern power converters, accommodating ripple currents up to 3.27 A. They also boast a long operational lifespan of 5000 hours at +105 °C, making them suitable for demanding applications that require over 25 years of performance in ambient temperatures reaching +60 °C.
The 193 PUR-SI series, characterized by a cylindrical aluminum case with a blue insulating sleeve, offers a range of capacitance from 47 µF to 820 µF across 25 compact case sizes. These RoHS-compliant components are ideal for applications in switch mode power supplies, electric vehicles, solar inverters, and more. Production quantities are currently available with lead times of 18 weeks.

MALVERN, Pa., Jan. 14, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today announced that the company has extended its 193 PUR-SI series of miniature snap-in power aluminum electrolytic capacitors with new voltage ratings of 550 V and 600 V. The Vishay BCcomponents devices deliver up to 30 % higher ripple current than standard solutions in similar case sizes and offer a longer useful life.
Traditionally, designers have used three 400 V to 450 V capacitors in series, with voltage balancing resistors across each device, to handle DC bus voltages up to 1100 V — an approach that adds design complexity and potential failure points. With their higher voltage ratings up to 600 V, the enhanced 193 PUR-SI series devices released today allow designers to achieve this voltage range with fewer components, while eliminating the need for voltage balancing circuits — saving PCB space and reducing BOM costs. In addition, the added voltage headroom extends capacitor lifetimes and enhances overall system reliability.
Designed to withstand the demanding switching currents of today’s high power converters, the 193 PUR-SI series devices handle ripple currents up to 3.27 A. Their long useful life of 5000 hours at +105 °C permits use in demanding applications requiring more than 25 years of operation from capacitors in ambient temperatures up to +60 °C. Featuring a cylindrical aluminum case insulated with a blue sleeve, the devices offer capacitance from 47 µF to 820 µF in 25 compact case sizes ranging from 22 mm x 25 mm to 35 mm x 60 mm. The RoHS-compliant capacitors are also available with 3-pin keyed polarity snap-in terminals for more stable PCB mounting.
As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the devices are ideally suited for smoothing, buffering, and DC-Link filtering in switch mode power supplies; chargers, battery management systems (BMS), and motor controls in electric (EV) and hybrid electric (HEV) vehicles; industrial motor drives and air conditioners; solar inverters; medical equipment; UPS; and welding equipment.
