LGC2H271MELC30

The LGC2H271MELC30 from Nichicon is a snap-in terminal, large-can aluminum electrolytic capacitor in the LGC series. It delivers 270 µF at a 500 V rating in a compact, one-rank-smaller-than-LGX case, designed to support equipment downsizing while maintaining long-life performance.

Intended for general-purpose high-voltage circuitry, the part combines a polarized aluminum electrolytic construction with snap-in radial mounting, RoHS compliance, and a rated operating range from −40°C to 105°C.

Key Features

• Capacitance and Voltage: 270 µF nominal capacitance at a 500 V rated voltage, with ±20% tolerance (120 Hz, 20°C).
• Snap-in Radial Package: Radial, can-type snap-in terminals for secure PCB mounting and mechanical stability in compact assemblies.
• Compact Size: One rank smaller case than the LGX series to support equipment downsizing; physical size approximately L: 3 cm × D: 3.5 cm.
• High Temperature Endurance: Rated for 5000 hours at 105°C under DC bias plus rated ripple current; meets endurance criteria when restored to 20°C.
• Wide Operating Temperature Range: Specified for −40°C to +105°C for use across a broad range of operating environments.
• Ripple Current Performance: Specified ripple current of 1.43 A at 120 Hz and 2.045 A at 50 kHz, with frequency coefficients available for design calculations.
• Electrical Reliability Metrics: Leakage current specified as I ≤ 3√(C·V) μA after 5 minutes at rated voltage (20°C); tan δ ≤ 0.25 (120 Hz, 20°C).
• RoHS Compliance: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose high-voltage circuits: Provides bulk capacitance at 500 V for general-purpose equipment where a compact, long-life capacitor is required.
• Compact power assemblies: One-rank-smaller can size and snap-in mounting support equipment downsizing and space-constrained board layouts.
• Industrial and commercial equipment: Designed for use across −40°C to +105°C environments with extended endurance (5000 hours at 105°C).

Unique Advantages

• Smaller footprint for downsized designs: One-rank-smaller case than LGX helps reduce enclosure and board space without changing the electrical rating.
• Long-life assurance at high temperature: Endurance specification of 5000 hours at 105°C provides predictable aging and service life planning.
• High-voltage capability: 500 V rating enables use in higher-voltage circuits while maintaining a compact package.
• Clear reliability specifications: Leakage current formula (I ≤ 3√CV μA) and tan δ ≤ 0.25 provide measurable electrical acceptance criteria for production and QA.
• Snap-in termination: Radial snap-in terminals simplify mechanical retention and assembly in printed circuit boards and power modules.
• Regulatory compliance: RoHS compliance supports environmentally regulated product development and procurement.
