LGU2D681MELA

The LGU2D681MELA from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGU series, specified for general‑purpose power applications. With a rated capacitance of 680 µF at 200 V and a temperature range of −40°C to 105°C, it is designed for bulk energy storage and ripple suppression in equipment that requires robust, high‑voltage electrolytic capacitors.

This part combines a compact φ25 × 35 mm can with snap‑in mounting, specified endurance under rated ripple at elevated temperature, and RoHS compliance—delivering a practical solution where reliable DC link or smoothing capacitance is required.

Key Features

• Capacitance and Voltage — 680 µF nominal capacitance at a 200 V rating, with a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High‑temperature Endurance — Rated for 3000 hours at 105°C with DC bias plus rated ripple current applied, meeting the LGU series endurance specification.
• Ripple Current Capability — Low‑frequency ripple current of 1.78 A (120 Hz) and high‑frequency ripple current of 2.67 A (50 kHz), supporting demanding smoothing and filtering loads across frequency ranges.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) of 0.15 measured at 20°C, 120 Hz, and leakage current specified at 1100 µA, enabling predictable ESR/impedance behavior for design calculations.
• Package and Mounting — Snap‑in radial can (φ25 × 35 mm) for board‑level insertion and secure mechanical mounting; supplied in tray packing for straightforward handling.
• Wide Operating Temperature — Rated for operation from −40°C to +105°C (applicable for 16 to 250 V range), accommodating many industrial and commercial environments.
• Compliance — RoHS‑compliant construction in accordance with applicable directives.

Typical Applications

• General Power Filtering — Bulk smoothing and ripple reduction in power supplies where 200 V rated capacitance is required.
• DC Link and Energy Storage — Local energy buffering in systems that need a compact, high‑voltage electrolytic solution with rated ripple endurance at 105°C.
• Industrial Equipment — Use in industrial power electronics and control equipment requiring robust electrolytic capacitance and snap‑in mounting for secure PCB attachment.

Unique Advantages

• Specified High‑Temperature Lifetime — 3000 hours endurance at 105°C under rated ripple, providing measurable durability for thermal stress cases.
• Frequency‑spanning Ripple Performance — Explicit ripple current ratings at both low (120 Hz) and high (50 kHz) frequencies allow designers to size capacitance for mixed‑frequency loads.
• Compact Snap‑In Form Factor — φ25 × 35 mm can with snap‑in terminals simplifies board mounting while delivering substantial capacitance for its size.
• Predictable Electrical Parameters — Defined tan δ (0.15 at 20°C/120 Hz) and leakage current (1100 µA) enable accurate modeling of ESR and standby loss in power designs.
• Tray Packing for Production — Supplied in trays to support efficient assembly and inventory handling for production environments.
• RoHS Compliance — Materials conform to RoHS requirements for environmentally regulated markets.
