LGN2H680MELZ30

The LGN2H680MELZ30 is a Nichicon LGN series aluminum electrolytic capacitor in a snap‑in radial can package. It provides 68 µF of capacitance at a rated voltage of 500 V and is polarized for general‑purpose power applications.

Designed for sustained operation at elevated temperatures, this snap‑in capacitor withstands 3000 hours of rated ripple current at 105°C and is RoHS compliant, offering a compact footprint (30 × 22 mm) in a one‑rank smaller case than the LGU series.

Key Features

• Capacitance & Rated Voltage — 68 µF nominal capacitance with a 500 V rated voltage for high‑voltage DC applications.
• High‑temperature Endurance — Specified operating range to 105°C and rated for 3000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current of 520 mA at 120 Hz and 743.6 mA at 100 kHz, validated for long endurance at elevated temperature.
• Compact Snap‑in Package — Radial, can-type snap‑in mounting with dimensions approximately 30 × 22 mm (L × D) for space‑efficient board layout; one rank smaller case than LGU.
• Electrical Characteristics — Polarized capacitor with capacitance tolerance of −20% to +20% and leakage current specified per datasheet formulas.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power electronics — Provides 68 µF at 500 V in designs requiring a polarized snap‑in electrolytic capacitor for high‑voltage circuits.
• High‑temperature environments — Suitable where components must tolerate sustained ripple handling and endurance at up to 105°C for extended periods.
• Space‑constrained power modules — Compact 30 × 22 mm can and snap‑in mounting allow denser board layouts while maintaining required voltage rating and capacitance.

Unique Advantages

• Long endurance at elevated temperature — 3000 hours at 105°C under rated ripple current supports designs that demand prolonged thermal reliability.
• Validated ripple performance — Specified ripple current values at 120 Hz and 100 kHz provide measurable guidance for thermal and life calculations.
• High working voltage — 500 V rating enables use in higher‑voltage DC systems without series stacking.
• Compact, serviceable form factor — Snap‑in radial can (30 × 22 mm) delivers a smaller case size compared with the LGU family, aiding compact power supply design.
• RoHS compliance — Meets RoHS requirements for use in regulations‑sensitive assemblies.
