|---|---|---|---|---|
| Jan 07 | Product launch | Positive | -2.2% | Launch of compact VT171P and VT172U transmissive sensors for industrial uses. |
| Jan 06 | Earnings date set | Neutral | -2.2% | Announcement of Q4 and full-year 2025 results release and conference call. |
| Dec 17 | Product launch | Positive | -2.1% | Introduction of S2F and S3F thin film chip fuses for broad applications. |
| Dec 11 | Industry award | Positive | +0.3% | SGTPL-28 space-grade planar transformers honored with 2025 AspenCore EE award. |
| Dec 10 | Product launch | Positive | +2.9% | Launch of NTCS0402E3104*XT AEC-Q200 NTC thermistor with wide temp range. |
Recent product and technology announcements have often produced modest, mixed price reactions, with several positive updates followed by short-term declines.
Over the last two months, Vishay has issued a series of product-focused announcements, including transmissive sensors on Jan 7, 2026, thin film chip fuses on Dec 17, 2025, and a new AEC-qualified thermistor on Dec 10, 2025. An award for its SGTPL-28 planar transformers was announced on Dec 11, 2025. Despite generally positive product positioning, 24-hour price moves after these releases ranged from about -2% to nearly +3%, indicating inconsistent near-term trading responses to similar news items.
Market Pulse Summary
The stock moved +6.6% in the session following this news. A strong positive reaction aligns with the company’s strategy of incremental product enhancements across its passive component portfolio. Recent history shows mixed immediate responses to similar product news, so an outsized move could reflect positioning rather than a structural shift. Investors may monitor upcoming earnings on Feb 4, 2026 and any follow-on design-win disclosures to gauge how higher-voltage, 5000 h-rated capacitors translate into demand and revenue over time.

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.
