LGC2H221MELA40

The LGC2H221MELA40 is a Nichicon LGC series large-can aluminum electrolytic capacitor in a snap-in terminal configuration. It delivers 220 µF at a 500 V rating in a compact 25 × 40 mm case, targeting equipment designs where high voltage, high ripple handling and reduced case size are required.

Designed for long-life operation up to 105°C, this snap-in capacitor is suited for general-purpose power and industrial applications that benefit from a smaller case size (one rank smaller than LGX) while retaining robust ripple and endurance characteristics. The part is RoHS compliant.

Key Features

• Capacitance and Voltage: 220 µF at 500 V for high-voltage energy storage and filtering in power circuits.
• Temperature Range: Rated for –40°C to +105°C for extended operating temperature capability.
• Long-Life Endurance: Endurance verified for 5000 hours at 105°C under DC bias plus rated ripple current, with capacitance change maintained within ±20%.
• Ripple Current Capability: Rated ripple current 1.36 A at 120 Hz and 1.945 A at 50 kHz, supporting heavy AC ripple conditions.
• Snap‑in Mounting: Radial can with snap-in terminals for secure board retention and quick assembly.
• Low‑temperature Stability: Impedance ratio Z(–25°C)/Z(+20°C) ≤ 8 (120 Hz) to support low-temperature performance.
• Leakage and Dissipation: Leakage current specification follows I ≤ 3√(C·V) (μA) after 5 minutes at 20°C; tan δ ≤ 0.25 (120 Hz, 20°C).
• Tolerance and Polarity: Capacitance tolerance ±20% (at 120 Hz, 20°C); polarized electrolytic construction.
• Marking and Compliance: Marked with white lettering on a black sleeve and compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering: Bulk and smoothing capacitor for high-voltage power supplies where 500 V rating and high ripple handling are required.
• Industrial power equipment: Energy storage and decoupling in industrial converters and inverters that operate up to 105°C.
• Equipment downsizing: Applications that require one rank smaller case size than LGX to reduce enclosure volume while maintaining long-life performance.

Unique Advantages

• High voltage in a compact can: 500 V rating combined with a 25 × 40 mm case lets designers meet high-voltage requirements without excessive board area.
• Long-life assurance at elevated temperature: 5000 hours at 105°C under DC bias plus rated ripple current provides predictable lifetime characteristics for sustained thermal stress.
• Strong ripple handling across frequencies: Specified ripple current values (1.36 A at 120 Hz; 1.945 A at 50 kHz) and frequency coefficients support a range of switching and line-frequency environments.
• Robust mounting: Snap-in terminals offer secure mechanical retention for heavy-current applications and simplify assembly.
• Temperature and low-temperature stability: Wide operating range (–40°C to +105°C) and controlled impedance behavior at low temperatures support reliable operation across varied environments.
• Regulatory compliance: RoHS compliance helps meet environmental and regulatory obligations for commercial and industrial equipment.
