LGU2G680MELY

The LGU2G680MELY is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in terminal package designed for general‑purpose applications requiring a 400 V polarized capacitor. It combines high‑voltage capability with a compact φ20×30 mm can and snap‑in mounting for secure mechanical retention in radial assemblies.

Key value comes from endurance and thermal performance: rated for operation up to 105°C with 3000 hours endurance under rated ripple conditions, low leakage, and specified ripple current across low and high frequencies to support stable performance in demanding environments.

Key Features

• Rated Voltage — 400 V nominal voltage suitable where high DC blocking or energy storage at elevated voltage is required.
• Capacitance & Tolerance — 68 µF with ±20% tolerance specified at 120 Hz, 20°C for predictable filtering and bulk storage.
• Package & Mounting — Snap‑in terminal, radial can (φ20×30 mm) for robust board retention and straightforward insertion into trays for volume assembly.
• Thermal & Endurance — Operating temperature range −25°C to 105°C and 3000 h endurance at 105°C when subjected to DC bias plus rated ripple current.
• Loss & Leakage — tanδ ≤ 0.15 (measured at 120 Hz, 20°C for this voltage class) and leakage current specified at 490 µA, supporting low loss and controlled leakage behavior.
• Ripple Current Capability — Rated ripple current of 560 mA at 120 Hz (low frequency) and 800.8 mA at 50 kHz (high frequency) for reliable ripple handling across common frequencies.
• Regulatory — RoHS compliant.

Typical Applications

• General Purpose Electronics — Use where a 400 V polarized aluminum electrolytic with snap‑in mounting is required for bulk capacitance or decoupling.
• Power Equipment — Suitable for equipment designs that call for high‑voltage capacitors with defined ripple current and endurance at elevated temperatures.
• Industrial Systems — Applicable in industrial assemblies needing RoHS‑compliant, long‑life capacitors in a compact radial can package.

Unique Advantages

• High‑Voltage Capability: 400 V rating provides headroom for designs that require higher DC voltage tolerance without increasing package size.
• Compact Snap‑In Form Factor: φ20×30 mm radial can with snap‑in terminals offers a space‑efficient solution that simplifies PCB retention and mechanical stability.
• Defined Endurance at Elevated Temperature: 3000 hours at 105°C under rated ripple current supports predictable long‑term performance in hotter operating environments.
• Frequency‑Aware Ripple Performance: Specified ripple current values at 120 Hz and 50 kHz enable designers to quantify thermal stress and cooling needs across low and high frequency applications.
• Controlled Loss and Leakage: Low tanδ and specified leakage help maintain efficiency and predictable behavior in energy storage and filtering roles.
• RoHS Compliant: Meets RoHS requirements for restricted substances, supporting regulatory needs for many product lines.
