LGUW6121MELA

The LGUW6121MELA is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series, specified for general‑purpose electronic applications. It provides 120 µF capacitance at a 420 V rating in a compact φ25×30L radial can package.

Designed for demanding thermal and ripple environments, this capacitor supports operation from −25°C to 105°C, a 3000‑hour endurance at 105°C, and rated ripple current handling for both low and high frequency applications.

Key Features

• Capacitance and Tolerance — 120 µF with ±20% tolerance measured at 120 Hz, 20°C.
• High Voltage Rating — Rated voltage of 420 V for higher‑voltage power designs.
• Snap‑in Radial Can Package — Snap‑in terminal, radial can (φ25×30L) for secure PCB mounting and mechanical stability; available in tray packing and produced for mass production.
• Wide Operating Temperature — Specified for −25°C to 105°C, matching LGU series temperature limits for 315–450 V parts.
• Endurance — Withstands 3000 hours of rated ripple current at 105°C with defined limits on capacitance change, tan δ and leakage current.
• High Ripple Current Capability — 750 mA at 120 Hz (low frequency) and 1.0725 A at 50 kHz (high frequency) to support smoothing and filtering under ripple stress.
• Leakage Current — Specified leakage current of 670 µA after standard application of rated voltage.
• Polarized — Polarized aluminum electrolytic construction for DC bulk energy storage and filtering applications.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power supplies — Bulk energy storage and output filtering where a 420 V rating and 120 µF capacitance are required.
• Industrial power equipment — DC link smoothing and ripple handling in industrial converters that operate up to 105°C.
• High‑voltage electronic modules — Energy storage and decoupling in systems requiring a compact, snap‑in high‑voltage capacitor.

Unique Advantages

• High‑voltage capability: 420 V rating enables use in higher‑voltage designs without parallel stacking of lower‑voltage parts.
• Designed for elevated temperature life: 3000 hours at 105°C provides predictable endurance under prolonged thermal stress.
• Dual‑frequency ripple performance: Rated ripple currents specified at both low (120 Hz) and high (50 kHz) frequencies allow selection based on the application’s ripple spectrum.
• Compact snap‑in form factor: φ25×30L radial can with snap‑in terminals simplifies board mounting and supports automated assembly in tray packing.
• Measured leakage specification: Defined leakage current (670 µA) after rated voltage application aids in power‑budget and reliability planning.
• Regulatory compliance: RoHS compliance supports deployment in regions with restricted substance requirements.
