LGU2E681MELA

The LGU2E681MELA is a Nichicon LGU series snap‑in aluminum electrolytic capacitor rated 250 V with 680 µF capacitance. It is a polarized, radial can snap‑in device designed for general‑purpose applications that require bulk capacitance and sustained ripple handling at elevated temperatures.

Key value comes from its 105°C endurance rating with 3000 hours of life, combined with high ripple‑current capability and low leakage, making it suitable where long‑term stability under continuous ripple and elevated temperature is required.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a rated voltage of 250 V with ±20% tolerance (120 Hz, 20°C).
• High‑temperature Endurance — Rated for 3000 hours at 105°C under DC bias plus rated ripple current; meets LGU series endurance criteria.
• Ripple‑current capability — 2000 mA at 120 Hz (low frequency) and 3000 mA at 50 kHz (high frequency), with frequency coefficients defined in the LGU series data.
• Low leakage and dissipation — Low leakage current (≈1.23 µA) and a tan δ of 0.15 measured at 20°C and 120 Hz for the 250 V rating, supporting efficient energy storage with minimal losses.
• Robust mounting — Snap‑in terminal, radial can package for secure mechanical and electrical connection in through‑hole assemblies.
• Operating range — Specified operating temperature range from −40°C to +105°C.
• Form factor & packaging — Size φ25 × 50 mm (L: 5 × D: 2.5 cm) with tray packing; available in mass production quantities.
• Regulatory — RoHS‑compliant per product data.

Typical Applications

• General‑purpose power systems — Bulk energy storage and smoothing in equipment that requires a 250 V, 680 µF polarized capacitor.
• High‑temperature environments — Designs requiring continuous operation at up to 105°C with long endurance (3000 hours) under rated ripple conditions.
• Through‑hole power assemblies — Applications utilizing snap‑in radial cans for secure mounting and reliable electrical connection.

Unique Advantages

• Long rated life at 105°C: 3000 hours endurance under rated conditions reduces capacitor replacement frequency in elevated‑temperature applications.
• High ripple‑current handling: 2 A (120 Hz) and 3 A (50 kHz) ratings provide margin for continuous ripple stress, improving thermal stability in power circuits.
• Low leakage and controlled dissipation: Low leakage current (~1.23 µA) and tan δ of 0.15 at 20°C/120 Hz support efficient performance and predictable ESR behavior.
• Secure snap‑in mounting: Radial, can snap‑in package enables robust mechanical retention for through‑hole assemblies.
• Tray packing and mass production availability: Supplied in trays and available in production quantities to support volume manufacturing and consistent supply.
