LGN2H680MELA25

The LGN2H680MELA25 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGN series. It offers a 68 µF capacitance at a 500 V rating in a compact φ25×25 mm can intended for general-purpose, high-voltage power applications.

Designed for durability under elevated operating conditions, this part delivers measurable ripple-handling and long endurance at high temperature, making it suitable for industrial and commercial power electronics where reliable bulk energy storage and filtering are required.

Key Features

• Electrical Rating: 68 µF capacitance at 500 V nominal with ±20% tolerance, suitable for high-voltage DC circuits and bulk energy storage.
• Loss and Measurement Conditions: tanδ (DF) specified at 0.20, measured at 20°C and 120 Hz, allowing predictable dissipation characteristics for design calculations.
• Ripple Current Capability: Low-frequency ripple current 520 mA (120 Hz) and high-frequency ripple current 743.6 mA (100 kHz), enabling effective smoothing under AC ripple across a range of switching frequencies.
• Leakage Current: Specified leakage current of 550 µA after rated voltage application, facilitating accurate stand-by and leakage budgeting.
• High-Temperature Endurance: Rated for 3000 hours at 105°C with DC bias plus rated ripple current applied, supporting extended service life in thermally demanding environments.
• Operating Range and Reliability: Operational temperature range from −25°C to +105°C and RoHS compliance for environmental compatibility.
• Package and Mounting: Snap-in radial can in a compact φ25×25 mm form-factor, supplied in tray packing for consistent handling in production environments.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and energy storage in high-voltage power supplies where 500 V rating and specified ripple currents maintain voltage stability under load.
• DC-Link and Converter Filtering: DC-link capacitance and filtering in power conversion systems that require endurance at elevated temperatures (3000 h at 105°C) and predictable ripple handling.
• Commercial Power Electronics: Energy buffering and ripple suppression in commercial UPS, inverters, and rectifier modules that operate at high voltages and elevated ambient temperatures.

Unique Advantages

• High Voltage Capability: 500 V rating enables use in higher-voltage DC circuits without series stacking, simplifying board design.
• Measured Dissipation Factor: tanδ specified at 0.20 (20°C, 120 Hz) gives designers a clear parameter for thermal and loss calculations.
• Frequency-Range Ripple Performance: Separate low- and high-frequency ripple current specifications (520 mA at 120 Hz, 743.6 mA at 100 kHz) support both legacy and switching-frequency designs.
• Proven Thermal Endurance: Rated endurance of 3000 hours at 105°C under rated ripple current helps ensure sustained performance in high-temperature installations.
• Compact Snap-In Form Factor: φ25×25 mm snap-in can provides robust mechanical mounting and space-efficient bulk capacitance for crowded power assemblies.
• RoHS Compliant: Conforms to RoHS requirements for environmentally conscious manufacturing and procurement.
