LGU1H123MELC

The LGU1H123MELC is an aluminum electrolytic capacitor in a snap-in terminal, radial can package designed for general-purpose applications. It provides 12,000 µF capacitance at a 50 V rating with a compact φ35×45L form factor and tray packing for production environments.

Engineered for sustained operation up to 105°C, this part delivers high ripple-current capability and long-term endurance — features suited to designs that require robust bulk capacitance and reliable high-temperature performance.

Key Features

• Capacitance and Voltage — 12,000 µF rated capacitance at 50 V, ±20% tolerance (measured at 120 Hz, 20°C), providing substantial bulk energy storage for general-purpose designs.
• High Ripple-Current Capability — Rated ripple current of 4.56 A at 120 Hz (low frequency) and 5.244 A at 50 kHz (high frequency), supporting applications with significant AC ripple stress.
• Endurance at Elevated Temperature — Specified to withstand 3,000 hours of rated ripple current at 105°C, delivering predictable aging and measurable life expectancy under sustained high-temperature loading.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) ≤ 0.30 at 20°C/120 Hz and a measured leakage current of 2,320 µA, supporting stable performance and predictable self-discharge behavior.
• Operating Temperature Range — Rated for −40°C to +105°C operation, enabling use across wide ambient conditions.
• Package and Mounting — Snap-in radial can (φ35×45L) designed for secure board mounting and mass-production tray packing for automated handling.
• Regulatory — RoHS compliant for restricted substance requirements.

Typical Applications

• General Purpose — Intended for designs that require a snap-in aluminum electrolytic capacitor with high capacitance, high ripple-current handling, and extended high-temperature endurance.

Unique Advantages

• High ripple-current endurance: 4.56 A (120 Hz) and 5.244 A (50 kHz) ratings reduce thermal stress during AC loading and help maintain capacitance stability under ripple conditions.
• Proven high-temperature life: 3,000-hour endurance at 105°C ensures predictable long-term behavior in thermally demanding installations.
• Large capacitance in a compact snap-in can: 12,000 µF in a φ35×45L package provides substantial bulk energy storage while remaining suitable for tray-based production handling.
• Controlled dielectric losses and leakage: tan δ ≤ 0.30 and specified leakage current of 2,320 µA support reliable filtering and energy-holding characteristics.
• Wide operating temperature range: −40°C to +105°C coverage allows deployment across a broad set of ambient conditions.
• RoHS compliance and mass-production readiness: Conforms to RoHS directive and is available in tray packing for high-volume assembly.
