LH Capacitors — SMD Aluminum Electrolytic Capacitor Manufacturer

01 / APPLICATIONS

Where our capacitors go to work

SMD aluminum electrolytic capacitors at work in four demanding fields — pick the series that fits your design.

Telecom & Network

Always-on
infrastructure.

Switching equipment, routers, modems and access terminals run around the clock, so their bulk capacitance has to stay stable year after year. Our SMD aluminum electrolytic capacitors — the wide-temperature LHA and the long-life LHB / LHD families — cover the duty cycle without drifting out of spec.

NoteLHA 1,000 h · LHB / LHD 2,000 h

Automotive

Built for the cabin
and the bay.

Infotainment, lighting and body-control modules pack dense SMD boards. LHA's −40 ~ +125°C rating spans cabin to under-hood, while the long-life LHB and LHD families hold their ratings through the whole temperature spread.

Industrial

Power that runs
for years.

Inverters, motor drives and machine power supplies run long duty cycles. LHB and LHD bring 2,000-hour load life and a wide capacitance range up to thousands of µF, keeping the DC bus steady from startup to maintenance interval.

Consumption

Small boards,
slim profiles.

Smart-home modules, wearables and portable audio pack hundreds of parts into a few square centimetres. LHO miniature cases — 3.95 mm tall — and the general-purpose LHA drop into standard footprints, keeping laptops, wearables and portable audio within their power budget.
