Panasonic Capacitors — Electrolytic, Film & Polymer

Panasonic Industry: A Global Leader in Capacitor Manufacturing

Panasonic Industry, a division of Panasonic Holdings Corporation, traces its capacitor manufacturing heritage back to Matsushita Electric Industrial Co., founded in 1918 by Konosuke Matsushita in Osaka, Japan. The company's electronic components division grew into one of the world's largest producers of passive components, with capacitor factories across Japan, China, Malaysia, and Indonesia.

In 2008, Matsushita Electric Industrial officially rebranded to Panasonic Corporation, unifying its global product lines under a single brand. The capacitor division, formerly known as Panasonic Electronic Components, now operates as part of Panasonic Industry Co., Ltd. — manufacturing aluminum electrolytic, conductive polymer, hybrid polymer, film, and ceramic MLCC capacitors for virtually every electronics sector.

Panasonic is particularly recognized for advancing conductive polymer and hybrid polymer electrolytic capacitor technology, offering lower ESR, longer lifespan, and higher ripple current ratings compared to traditional wet aluminum electrolytics. These innovations have made Panasonic a preferred supplier for automotive, LED lighting, and power supply applications.

Matsushita to Panasonic: Cross-Referencing Legacy Part Numbers

Many older designs and maintenance manuals still reference Matsushita part numbers from before the 2008 rebrand. These parts are functionally identical to their Panasonic-branded successors, but the part numbering system was updated in many cases. For example, legacy Matsushita electrolytic capacitors may carry prefixes that differ from the current Panasonic naming convention.

Specap maintains cross-reference data for Matsushita-to-Panasonic part number transitions. If you have a legacy BOM or service manual with Matsushita part numbers, our team can identify the current Panasonic equivalent or a compatible alternative from another manufacturer. Use our cross-reference tool to start a search, or request a quote with your Matsushita or Panasonic part number for manual cross-reference assistance.

Industries Served by Panasonic Capacitors

Panasonic capacitors are used across a broad range of industries worldwide:

• Automotive — Panasonic hybrid polymer and ceramic capacitors are qualified for under-hood and ADAS applications, meeting AEC-Q200 requirements for vibration, temperature, and humidity resistance.
• Consumer electronics — From smartphones to home appliances, Panasonic MLCC and aluminum electrolytic capacitors are found in millions of consumer products globally.
• Industrial equipment — Panasonic FR and FC series electrolytics are widely used in industrial power supplies, motor drives, and inverter circuits where low ESR and high ripple current are critical.
• LED lighting — Hybrid polymer capacitors from Panasonic provide the long operational life and high-temperature performance required in LED driver circuits.
• Power supply design — Panasonic's polymer and electrolytic capacitor lines are staples in SMPS output filtering, providing stable voltage regulation with minimal ripple.

Why Source Panasonic Capacitors from Specap?

With over 40 years in the capacitor business, Specap provides reliable access to both current-production and obsolete Panasonic capacitors. Whether you need a current EEH-ZC hybrid polymer for a new design or a discontinued Matsushita electrolytic for legacy equipment maintenance, we can help:

• Stock current Panasonic production lines including FC, FM, FR, and hybrid polymer series
• Source discontinued and obsolete Panasonic and Matsushita parts through our global network
• Cross-reference legacy Matsushita part numbers to current Panasonic or alternative equivalents
• Verify authenticity and test electrical parameters before shipping

Every capacitor we ship is electrically tested and inspected — no counterfeits, no relabeled parts.
