LGUW6101MELY

The LGUW6101MELY is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LGU series, specified for general‑purpose power applications. It combines a high 420 V rated voltage with 100 µF capacitance and polarized snap‑in packaging for secure board mounting.

Engineered for elevated operating conditions, this part is rated for operation up to 105°C and is specified to withstand 3000 hours of rated ripple current at 105°C, offering durable performance for high‑voltage DC circuits and power systems where sustained ripple handling and temperature endurance are required.

Key Features

• High Voltage & Capacitance — 420 V rated voltage with 100 µF nominal capacitance and ±20% tolerance for energy storage and DC smoothing in high‑voltage circuits.
• 105°C Endurance — Rated for continuous operation to 105°C with an endurance specification of 3000 hours at 105°C under rated ripple conditions, supporting long‑term reliability in elevated ambient temperatures.
• Snap‑In Radial Can Package — Snap‑in terminal, radial can configuration provides secure mechanical retention on the PCB for robust mounting in power assemblies.
• Ripple Current Capability — Supports 700 mA at 120 Hz and 1.001 A at 50 kHz, enabling effective ripple absorption across low and high frequencies common in switched and linear power supplies.
• Operating Temperature & Polarization — Polarized capacitor rated for −25°C to +105°C operating range, suitable where polarized high‑voltage electrolytic capacitance is required.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU,(EU)2015/863), meeting common regulatory requirements for hazardous substance restriction.
• Compact Footprint — Physical size L: 3.5 × D: 2 cm for space‑efficient placement in power assemblies.

Typical Applications

• Power supply filtering and smoothing — 420 V rating and 100 µF capacitance provide bulk energy storage and ripple suppression for high‑voltage DC rails.
• Industrial power electronics — 105°C rating and 3000 h endurance at rated ripple current suit sustained operation in industrial environments with elevated temperatures.
• High‑frequency ripple mitigation — Rated ripple current up to 1.001 A at 50 kHz supports suppression of switching noise in frequency‑converted or high‑speed power stages.

Unique Advantages

• High‑voltage capability: 420 V rating enables use in higher DC bus and HV power circuits without paralleling lower‑voltage parts.
• Elevated temperature endurance: 105°C rating with 3000 hours endurance under rated ripple current reduces performance drift in hot operating environments.
• Robust ripple handling: Specified ripple current values at both 120 Hz and 50 kHz let designers size capacitors against real‑world ripple profiles.
• Secure PCB retention: Snap‑in terminals simplify assembly and provide mechanical stability in vibration‑prone applications.
• Regulatory compliance: RoHS conformity supports deployments where hazardous substance restrictions apply.
