LGU1C273MELC

The LGU1C273MELC is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGU series, offering 27,000 µF capacitance at a 16 V rating with ±20% tolerance. Engineered for general-purpose power applications, it delivers high bulk capacitance in a compact φ35 × 30 mm can and is optimized for sustained ripple handling and long-term endurance.

Designed to operate across –40°C to 105°C and rated for 3,000 hours at 105°C under specified ripple conditions, this part targets power filtering and energy-storage roles where large capacitance, reliable ripple endurance, and tray-friendly packing are required.

Key Features

• High Capacitance — 27,000 µF (27 mF) provides substantial bulk energy storage for smoothing and hold-up tasks in power electronics.
• Rated Voltage and Tolerance — 16 V nominal rating with ±20% capacitance tolerance at 120 Hz and 20°C for predictable performance in DC supply circuits.
• Snap-in Mounting — Radial, can-style snap-in terminals simplify board assembly and secure mechanical retention for higher-current power assemblies.
• Ripple Endurance — Rated ripple current handling of 3.74 A at 120 Hz (low frequency) and 4.301 A at 50 kHz (high frequency) for sustained AC loading scenarios.
• Long Endurance — Specified to withstand 3,000 hours at 105°C with rated ripple current applied, meeting the LGU series endurance criteria.
• Electrical Loss Characteristic — tan δ (DF) max 0.50 measured at 20°C and 120 Hz for the 16 V rating, useful for assessing dissipation under AC conditions.
• Leakage Current — 1,970 µA initial leakage current specified after standard voltage application at 20°C.
• Packaging & Production — Tray packing and mass production status support volume assembly and supply continuity.
• RoHS Compliant — Meets RoHS requirements for lead-free environmental compliance.

Typical Applications

• General-purpose power filtering — Bulk capacitance and rated ripple capability make it suitable for smoothing DC rails and reducing voltage ripple.
• Energy storage / hold-up — Large µF value supports short-term energy buffering in power supplies and backup circuits.
• Industrial electronics — Robust endurance at 105°C and snap-in mounting address demanding thermal and mechanical environments found in industrial power assemblies.

Unique Advantages

• Substantial bulk capacitance: 27,000 µF supplies high energy density in a compact φ35 × 30 mm package to reduce board space compared with multiple smaller capacitors.
• Designed for sustained ripple: Rated ripple current at both low and high frequencies (3.74 A at 120 Hz, 4.301 A at 50 kHz) supports long-term AC loading without premature degradation.
• High-temperature endurance: 3,000-hour life at 105°C with applied ripple current provides predictable long-term behavior in elevated-temperature installations.
• Snap-in, tray-ready format: Radial snap-in terminals and tray packing simplify high-volume assembly and handling for production lines.
• Clear electrical characterization: Specified tan δ and leakage current values allow straightforward integration and thermal/power-loss budgeting in designs.
• Environmental compliance: RoHS conformity supports deployment in regulated markets requiring lead-free components.
