Lelon industrial electrolytic and polymer capacitors

Lelon Electronics engineering heritage and global manufacturing scope

Lelon Electronics Corp. founded in 1976 by T. C. Wu stands as a global technological manufacturer of electrolytic capacitors. Over fifty years of continuous development the brand established automated manufacturing facilities across Taiwan and mainland facilities.

Lelon operational strategy relies on comprehensive vertical integration, producing high-purity formed aluminum foils and designing precision automated production machinery in-house.

Lelon electrolytic capacitors are deployed in mission-critical applications across automotive electronics, telecommunications, cloud server infrastructure, and power electronics networks.

Organic conductive polymer capacitors OP-CAP series architecture

The Lelon OP-CAP family of solid conductive polymer capacitors delivers high-frequency filtering for secondary switching power supplies and modular DC-DC converters.

Built with a solid organic conductive polymer electrolyte, these components achieve ultra-low equivalent series resistance ESR in high-frequency ranges while handling massive ripple currents without thermal buildup.

Unlike liquid electrolytes, the solid polymer structure avoids dry-out degradation over time and retains stable capacitance across wide temperature ranges in both SMD V-Chip and radial leaded configurations.

Conductive polymer hybrid capacitors for harsh automotive environments

Lelon conductive polymer hybrid capacitors integrate solid polymer materials and liquid electrolyte chemistry to achieve an optimal balance between low impedance and high dielectric withstand voltage up to 100V.

The liquid electrolyte ensures continuous self-healing of the aluminum oxide dielectric layer under electrical transient pulses, while the polymer electrolyte delivers low ESR and high ripple tolerance.

Engineered for engine compartments and vehicle inverters reaching plus 135 degrees C, these components adhere to rigorous automotive manufacturing criteria under IATF 16949.

High-density V-Chip SMD capacitors and anti-vibration structures

Lelon V-Chip SMD aluminum electrolytic capacitors are engineered for dense automated surface mount placement with lead-free reflow soldering. The specialized high-temperature polymer base plate ensures accurate lead terminal alignment on PCB pads and reliable solder fillet formation.

For industrial machinery and transport systems exposed to heavy mechanical shocks, Lelon supplies reinforced anti-vibration terminal structures capable of enduring accelerations up to 30G. Operating endurance ratings reach up to 10000 hours in continuous industrial duty environments.

High-capacitance snap-in capacitors for industrial motor drives

For high-voltage DC-link intermediate circuits inside frequency inverters, uninterruptible power systems, and welding machines, Lelon developed high-capacitance snap-in capacitors.

Rigid spring-action terminals secure the component into PCB through-holes prior to wave soldering, guaranteeing mechanical rigidity.

Rated for operational voltages from 160V to 500V, these capacitors provide massive electrostatic energy storage and smooth high ripple current pulses from three-phase AC mains. A safety vent prevents structural rupture under abnormal line surges.

Heavy-duty screw terminal power capacitors for renewable energy and UPS

Heavy-duty industrial capacitors from Lelon featuring rugged threaded screw terminals are built for megawatt-scale power installations including electric railway traction inverters, utility solar plants, wind turbine converters, and electrolytic cells.

Heavy screw terminals allow secure bolting to high-current copper busbars carrying hundreds of amperes without joint heating.

Aluminum cylinder shells are enclosed in heat-shrink insulating sleeves and fitted with safety pressure vents, providing long operational endurance for utility and manufacturing substations.
