Insights

Electronics Components Strategist

Vishay's DLA‑approved polymer capacitors strengthen its AMS parts portfolio; product reliability and long lead time are key investor considerations.

Vishay adds a DLA 04051‑compliant vPolyTan™ polymer chip capacitor family that spans 4.7 μF–680 μF and 2.5 V–63 V, and reports ultra‑low ESR down to 25 mΩ plus 2000 hours at 125 °C validation. The parts target high‑reliability uses in power supplies, radios, radars and transponders and are positioned explicitly as a second source to Yageo/Kemet, which supports qualification and BOM substitution in aerospace and military designs.

Primary dependencies and risks include qualification uptake by prime contractors and the quoted 35 weeks lead time, which could constrain near‑term revenue from production orders despite sample availability now. Watch for volume order wins, formal OEM qualifications, and any changes to lead time or additional test data; these items typically resolve over a 6–18 month horizon for AMS part adoption.

New DLA 04051 Series Delivers Ultra Low ESR, Capacitance Range of 4.7 μF to 680 μF, and Voltage Ratings Up to 63 V

MALVERN, Pa., Oct. 08, 2025 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today announced the release of its new DLA 04051 series of vPolyTan™ polymer surface-mount chip capacitors. These capacitors are designed for high-reliability applications in the aerospace, military, and space (AMS) markets, meeting the latest Defense Logistics Agency (DLA) 04051 military specifications.

The DLA 04051 series features ultra-low ESR, as low as 25 mΩ, significantly lower than traditional tantalum capacitors, making them ideal for power supplies, radios, radars, transponders, and energy storage in AMS systems. The capacitors offer a wide capacitance range of 4.7 μF to 680 μF and support voltage ratings from 2.5 V to 63 V. They are also tested for long-term reliability, validated through 2000 hours of testing at 125 °C.

In addition to their electrical performance, these capacitors deliver robust mechanical reliability, including shock resistance up to 500 g, vibration resistance meeting MIL-STD-202-204 Level D, and the ability to withstand 10 thermal shock cycles per MIL-STD-202-107. Vishay’s DLA 04051 series serves as a true second source to Yageo/Kemet offerings, ensuring compatibility and reliability for critical military and aerospace systems.

Samples and production quantities of the DLA 04051 series are available now, with lead times of 35 weeks.
