LGX2H221MELC35

The LGX2H221MELC35 is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon's LGX series designed for general power applications. It provides 220 µF capacitance at a 500 V rating in a radial, snap‑in can package.

Engineered for high‑temperature endurance, this part withstands 5000 hours of rated ripple current at 105°C and is suited for rectifier circuits in general inverters and switching power supplies. It is RoHS compliant for environmental regulation adherence.

Key Features

• Electrical performance — 220 µF nominal capacitance with ±20% tolerance and a 500 V rated voltage for high‑voltage power systems.
• High ripple capability — Rated ripple current of 1.23 A at 120 Hz and 1.759 A at 50 kHz to support sustained AC ripple in power-conversion circuits.
• Long‑life endurance — Designed to meet endurance requirements after 5000 hours of D.C. bias plus rated ripple current at 105°C; capacitance change within ±20%, tan δ under 200% of initial spec, leakage current ≤ initial value.
• Wide operating temperature — Specified for -25°C to +105°C operation to accommodate elevated ambient or enclosure temperatures.
• Snap‑in radial can package — Snap‑in terminals and radial can construction for secure PCB mounting and robust mechanical connection.
• Regulatory compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General inverters (rectifier circuits) — Provides filter and energy‑storage capability on rectifier stages where high voltage and endurance at elevated temperature are required.
• Switching power supplies — Used for smoothing and ripple reduction in high‑voltage power conversion stages.
• General purpose power applications — Suitable for power‑filtering and energy‑buffering roles in industrial and commercial equipment within the stated temperature and voltage limits.

Unique Advantages

• Extended high‑temperature life — 5000 hours endurance at 105°C under rated ripple current reduces maintenance and replacement frequency in hot environments.
• High voltage capability — 500 V rating supports designs that require elevated DC bus or rectifier voltages without series stacking.
• Robust ripple handling — Explicit ripple current ratings at both 120 Hz and 50 kHz give designers quantifiable limits for thermal and lifetime calculations.
• Compact radial snap‑in form — Snap‑in can package enables secure mounting and straightforward assembly in power electronics layouts.
• Wide operating range — Specified −25°C to +105°C operation accommodates a broad range of environmental conditions.
• RoHS compliant — Meets current RoHS requirements for material compliance in commercial and industrial equipment.
