6 terms

dc-link filtering technical

"suited for smoothing, buffering, and DC-Link filtering in switch mode power supplies"

Dc-link filtering is the use of electrical components to smooth and clean the main direct‑current connection inside a power converter or inverter, reducing voltage wiggles and electrical noise that can stress components. For investors, better dc-link filtering means products run more reliably, use energy more efficiently, and meet regulatory limits on interference — factors that reduce warranty costs, improve product performance, and influence competitiveness.

switch mode power supplies technical

"DC-Link filtering in switch mode power supplies; chargers, battery management systems"

Switch mode power supplies are electronic units that convert one voltage of electricity to another by rapidly turning the input power on and off and smoothing the output, like a fast faucet that adjusts water flow to the right pressure. They matter to investors because they affect the efficiency, size, heat, reliability and cost of a company’s electronic products; performance or supply issues can influence manufacturing costs, product competitiveness and profit margins.

battery management systems (BMS) technical

"chargers, battery management systems (BMS), and motor controls in electric (EV)"

A battery management system (BMS) is the electronic controller that monitors and protects rechargeable battery packs by measuring charge levels, balancing individual cells, managing temperature, and preventing unsafe conditions like overcharge or overheating. For investors, a reliable BMS improves a battery product’s safety, lifespan and performance — which lowers warranty costs, supports regulatory approval and boosts the commercial value of electric vehicles, grid storage and any product relying on batteries, much like a trained driver keeping a car running efficiently and safely.

rohs-compliant regulatory

"The RoHS-compliant capacitors are also available with 3-pin keyed polarity"

RoHS-compliant means a product meets rules that limit or ban certain hazardous chemicals in electrical and electronic equipment, ensuring the item does not contain those restricted substances above set limits. For investors this matters because compliance affects a company's ability to sell in regulated markets, avoid fines and recalls, and manage production costs and supply-chain risks—similar to a food product following a recipe that omits banned ingredients to stay sellable and safe.

non-solid electrolyte technical

"As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the devices"

A non-solid electrolyte is a liquid or gel substance that carries charged particles between a battery’s positive and negative ends, typically an organic solvent with dissolved salts. Investors pay attention because these electrolytes offer high conductivity and are used in most current batteries but bring safety and longevity trade-offs—think of a machine that runs well with oil but risks leaks and fire—so a move to solid alternatives can affect a maker’s performance, costs and risk profile.

snap-in power aluminum electrolytic capacitors technical

"series of miniature snap-in power aluminum electrolytic capacitors with new voltage"

A snap-in power aluminum electrolytic capacitor is an electronic component that stores and releases electrical energy, built with aluminum plates and a conductive liquid, and fitted with sturdy snap-in leads for quick mounting on circuit boards. Think of it as a shock absorber or short-term savings account for electricity that smooths voltage and supplies bursts of power; its reliability, size, cost and supply affect product performance, manufacturing yields and long-term maintenance costs—key concerns for investors in electronics and power-related businesses.

Space- and Cost-Saving Devices Offer Ripple Current to 3.27 A and Useful Life of 5000 Hours at +105

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.
