LGN2C681MELA25

The LGN2C681MELA25 from Nichicon is a snap-in terminal, large-can aluminum electrolytic capacitor providing 680 µF capacitance at a 160 V rating. It is part of the LGN series designed for general-purpose applications that require substantial bulk capacitance, elevated ripple handling and extended high-temperature endurance.

Key attributes include snap-in mounting for secure board retention, compact φ25 × 25 mm can size, rated operation from −40°C to 105°C, and a guaranteed endurance of 3000 hours at 105°C when used within rated conditions.

Key Features

• Capacitance & Rated Voltage — 680 µF nominal capacitance with a 160 V rated voltage, suitable for designs requiring significant bulk energy storage.
• Capacitance Tolerance — ±20% (measured at 120 Hz, 20°C), providing predictable selection margins for power designs.
• High Ripple Current Handling — Rated low-frequency ripple current of 1.7 A at 120 Hz and high-frequency ripple current of 2.55 A at 100 kHz, supporting demanding ripple conditions.
• Thermal and Endurance Performance — Operating temperature range −40°C to 105°C with endurance specified at 3000 hours at 105°C under rated ripple and DC bias.
• Low Loss and Leakage — Tangent of loss angle (tan δ) max 0.15 (120 Hz, 20°C) and leakage current approximately 980 µA, supporting efficient energy storage with controlled losses.
• Snap-In, Radial Can Package — Snap-in terminal type in a φ25 × 25 mm can (tray packed, mass production status) for reliable mechanical retention and board-level mounting.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.

Typical Applications

• General Purpose Power Electronics — Bulk capacitance and rated ripple capability make this part applicable where 160 V, 680 µF smoothing or energy storage is required.
• Industrial Equipment — Suitable for equipment operating across −40°C to 105°C with long endurance demands (3000 hours at 105°C).
• High-Ripple Environments — Use in designs that must tolerate significant ripple currents at both low and high frequencies, leveraging the 1.7 A (120 Hz) and 2.55 A (100 kHz) ratings.

Unique Advantages

• Balanced capacitance and voltage — 680 µF at 160 V provides a strong capacitance-to-voltage combination for bulk storage in medium-voltage circuits.
• Long high-temperature endurance — Rated for 3000 hours at 105°C under specified conditions, enabling extended service life in hot operating environments.
• Robust ripple performance — Specified ripple currents for both low and high frequencies reduce thermal stress and support reliable operation under AC ripple loading.
• Compact snap-in can — φ25 × 25 mm package in a snap-in format offers secure board mounting with a smaller case footprint relative to previous series ranks.
• Controlled losses and leakage — Low tan δ (0.15 max) and typical leakage around 980 µA contribute to efficient power-stage performance.
• Environmentally compliant — RoHS compliance supports regulatory and sourcing requirements.
