LGC2H561MELC50

The LGC2H561MELC50 is a snap-in terminal, polarized aluminum electrolytic capacitor from Nichicon’s LGC series. It provides 560 µF capacitance at a 500 V rating in an ultra-smaller-sized radial can designed to support equipment downsizing.

Engineered for long-life operation up to 105°C, this capacitor is RoHS compliant and targeted at general-purpose electrical equipment where high-voltage energy storage, compact packaging and extended high-temperature endurance are required.

Key Features

• Electrical — 560 µF nominal capacitance with a 500 V rated voltage and ±20% tolerance (at 120 Hz, 20°C); polarized design for DC applications.
• Thermal & Long-Life — Rated for operation from −40°C to +105°C with a specified endurance of 5000 hours at 105°C under D.C. bias plus rated ripple current.
• Package & Mounting — Snap-in terminal, radial can (snap-in) construction; ultra-smaller-sized case (one rank smaller than LGX) to support compact board layouts. Size listed as L: 5 × D: 3.5 cm.
• Ripple Handling — Rated ripple currents: 2.23 A at 120 Hz (low frequency) and 3.189 A at 50 kHz (high frequency); frequency coefficients provided in the series datasheet for scaling ripple capability across frequencies.
• Reliability Characteristics — Leakage current defined by I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ ≤ 0.25 (120 Hz, 20°C); impedance stability Z(−25°C)/Z(+20°C) ≤ 8 (120 Hz).
• Endurance & Shelf Life — After 5000 hours at 105°C with rated stress, capacitance retention and leakage current limits are specified by the series endurance criteria; shelf-life recovery procedure and limits are defined in the datasheet.
• Compliance & Identification — Compliant with RoHS directives (2011/65/EU, (EU)2015/863); sleeve marked with white letters on black for clear identification.

Typical Applications

• General Purpose Equipment — Suited for general-purpose electrical circuits that require polarized, high-voltage capacitance in a snap-in package.
• Compact / Downsized Systems — One rank smaller case than LGX makes the LGC2H561MELC50 useful where reduced component footprint is required for equipment downsizing.
• High-Temperature, Long-Life Designs — Designed for applications requiring continuous operation at elevated temperatures, supported by a 5000-hour rating at 105°C.

Unique Advantages

• High Voltage Capability: 500 V rated voltage provides large DC energy storage in a single component, reducing the need for multiple parallel parts.
• Compact Form Factor: Ultra-smaller-sized radial snap-in can (one rank smaller than LGX) helps save PCB real estate for compact equipment layouts.
• Extended High-Temperature Life: Endurance specified at 5000 hours at 105°C gives predictable aging characteristics for sustained high-temperature operation.
• Defined Ripple Performance: Explicit ripple current ratings at 120 Hz and 50 kHz and frequency coefficients permit accurate thermal and ripple budgeting in power designs.
• Measured Electrical Stability: Clear limits for leakage current, tan δ and low-temperature impedance ensure verifiable performance under defined conditions.
• Regulatory Compliance: RoHS compliance supports deployment in regions and products where restricted-substance adherence is required.
