LGUW6820MELY

The LGUW6820MELY is an LGU series aluminum electrolytic capacitor in a snap‑in radial can package designed for general‑purpose power applications. It delivers 82 µF capacitance at a 420 V rating with polarized snap‑in terminals for reliable board mounting.

Engineered for sustained performance, the device offers high ripple current handling and a 3000‑hour endurance at 105°C, making it suitable for demanding commercial and industrial power designs that require high‑voltage bulk storage and smoothing.

Key Features

• Capacitance & Tolerance: 82 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable energy storage and filtering behavior.
• Rated Voltage: 420 V DC rating for high‑voltage power rails and energy storage applications.
• Ripple Current Performance: 640 mA at low frequency (120 Hz) and 915.2 mA at high frequency (50 kHz) to support continuous ripple current loading common in power conversion circuits.
• Endurance at Elevated Temperature: Rated for 3000 hours at 105°C under DC bias plus rated ripple current, providing long‑term stability in hot operating environments.
• Low Leakage Current: 550 µA specified leakage current for reduced standby losses and predictable behavior after voltage application.
• Operating Temperature Range: –25°C to +105°C, suitable for a wide range of commercial and industrial ambient conditions.
• Package & Mounting: Snap‑in terminal, radial can construction (φ20 × 35 L, approx. 3.5 × 2.0 cm), supplied in tray packing and available as a mass‑production part for scalable assembly.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for regulatory compliance in global supply chains.

Typical Applications

• Power supply bulk smoothing: 420 V rating and 82 µF capacitance provide bulk energy storage and smoothing on high‑voltage DC rails.
• Industrial power conversion: High ripple current capability and 105°C endurance suit inverter and converter DC link applications in industrial equipment.
• Commercial UPS and energy storage systems: Polarized snap‑in mounting and long endurance support reliable operation in standby and backup power modules.

Unique Advantages

• High‑voltage capability: 420 V rating enables use on elevated DC rails without compromise to capacitance value.
• Designed for continuous ripple: Specified ripple currents at both low and high frequencies reduce thermal stress and improve operational longevity under AC loading.
• Extended high‑temperature endurance: 3000 hours at 105°C under rated conditions gives confidence in long‑term stability in hot enclosures.
• Compact radial snap‑in package: φ20×35 L can with snap‑in terminals simplifies board mounting for high‑volume assemblies.
• Predictable leakage and tolerance: Specified 550 µA leakage and ±20% capacitance tolerance enable accurate design margins and performance modeling.
• Regulatory readiness: RoHS compliance supports use in global commercial and industrial products.
