LGC2H271MELB35

The LGC2H271MELB35 is an aluminum electrolytic, snap-in terminal capacitor from Nichicon’s LGC series designed for long-life, high-voltage applications. It delivers 270 µF at a 500 V rating in an ultra-smaller-sized snap-in can, providing high-voltage bulk capacitance in a reduced footprint.

Intended for general-purpose equipment, the part is optimized for downsized assemblies and environments requiring extended endurance up to 105°C.

Key Features

• Capacitance & Voltage: 270 µF nominal capacitance with a rated voltage of 500 V, suited for high-voltage bulk energy storage.
• Compact Snap-In Package: Radial, can-type snap-in mounting (30 × 35 mm / L: 3.5 cm × D: 3 cm) enabling secure board attachment while reducing case size compared with the LGX series.
• High Temperature Endurance: Rated for operation from –40°C to +105°C with long-life endurance specified as 5000 hours at 105°C under rated DC bias plus ripple current.
• Ripple Current Capability: Rated ripple current of 1.48 A at 120 Hz and 2.116 A at 50 kHz, with frequency coefficients provided in the datasheet for other operating frequencies.
• Leakage Current Specification: Leakage current follows I ≤ 3√(C·V) µA after 5 minutes’ application of rated voltage at 20°C, per the datasheet definition.
• Electrical Stability: Capacitance tolerance ±20% (at 120 Hz, 20°C) and low-temperature impedance stability Z(–25°C)/Z(+20°C) ≤ 8 at 120 Hz as documented in the series datasheet.
• RoHS Compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electrical equipment: Provides high-voltage bulk capacitance where long life at elevated temperatures is required.
• Equipment downsizing projects: One rank smaller case size than the LGX series makes this part suitable for designs targeting reduced enclosure volume.
• High-voltage smoothing and energy storage: 500 V rating and 270 µF capacitance provide substantial stored energy for systems that require elevated DC bus capacitance.

Unique Advantages

• High-voltage bulk in a compact can: 500 V and 270 µF in a 30 × 35 mm snap-in package reduces space without sacrificing capacitance.
• Designed for long operation at elevated temperature: 5000 hours endurance at 105°C supports reliable performance in thermally demanding installations.
• Robust ripple handling: Defined ripple current ratings at 120 Hz (1.48 A) and 50 kHz (2.116 A) help designers size components for expected AC stress.
• Predictable leakage behavior: Leakage current governed by I ≤ 3√(C·V) µA (after 5 minutes at 20°C) gives a clear basis for system leakage budgeting.
• Snap-in mounting for secure assembly: Radial snap-in terminals enable reliable mechanical retention for high-current, high-voltage PCB layouts.
• Regulatory compliance: RoHS conformity supports use in equipment requiring restricted-substance compliance.
