LGJ2W121MELB20

The LGJ2W121MELB20 is a snap‑in terminal aluminum electrolytic capacitor in Nichicon’s LGJ series, designed for general purpose applications that require high‑voltage, high‑temperature bulk capacitance in a low‑profile package. It provides 120 µF nominal capacitance at a rated voltage of 450 V, combined with long endurance and robust ripple handling for demanding operational environments.

Key Features

• Capacitance & Tolerance — 120 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• High Voltage Rating — Rated for 450 V to support high‑voltage DC applications.
• Temperature & Endurance — Operating temperature range −25°C to +105°C with a rated lifetime of 3000 hours at 105°C.
• Ripple Current Capability — Rated ripple current of 870 mA at 120 Hz (low frequency) and 1.244 A at 50 kHz (high frequency), suitable for AC ripple filtering and decoupling duties at those frequencies.
• Leakage Current — Specified leakage current of 690 µA after rated voltage application.
• Package & Mounting — Snap‑in terminal, radial can package (φ30 × 20 mm); tray packing for production handling.
• Polarized Electrolytic — Polarized device for DC and power applications.

Typical Applications

• General Purpose Electronics — Acts as bulk capacitance and ripple filter where a 450 V, 120 µF polarized capacitor is required.
• High‑Temperature Environments — Suited to designs that require operation up to 105°C and stable performance over a specified 3000 h lifetime at that temperature.
• Power‑Handling Assemblies — Used in assemblies that need robust ripple current capability at both low and high frequencies.

Unique Advantages

• High‑voltage capability: 450 V rating enables use in high‑voltage DC circuits without series stacking.
• Compact low‑profile footprint: φ30 × 20 mm can dimensions provide substantial capacitance in a reduced height for space‑constrained layouts.
• Robust thermal endurance: Rated for −25°C to 105°C with a 3000 h life at 105°C, supporting elevated ambient operation.
• Wide ripple handling range: Specified ripple currents at 120 Hz and 50 kHz demonstrate capability across common power‑conversion frequencies.
• Production‑friendly packaging: Tray packing supports mass production handling and assembly processes.
