LGG2E681MELZ45

The LGG2E681MELZ45 is a 680 µF, 250 V aluminum electrolytic capacitor from Nichicon’s LGG series, configured with snap‑in terminals for secure PCB mounting. Designed as a compact, high‑performance electrolytic, it targets general‑purpose power applications where high ripple handling, 105 °C endurance and reduced board footprint are priorities.

As part of the LGG series, this snap‑in terminal type provides a smaller case profile compared with previous LGN series sizes and is RoHS compliant. It is available in mass production packaging suitable for volume designs.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 250 V for energy storage and decoupling in medium‑voltage circuits.
• Snap‑in Mounting & Package — Radial can with snap‑in terminals for robust mechanical retention and rapid assembly on PCBs.
• Compact, Space‑Saving Size — Dimension φ22 × 45 mm (L: 4.5 × D: 2.2 cm) and specified as one rank smaller than LGN series cases to support equipment downsizing.
• High Ripple Current Capability — Rated low‑frequency ripple current 1.5 A at 120 Hz and high‑frequency ripple current 2.25 A at 100 kHz for demanding ripple environments.
• Endurance at Elevated Temperature — 2000 hours rated life at 105 °C under rated conditions, meeting LGG series endurance specifications.
• Wide Operating Temperature — −40 °C to +105 °C operational range for broad environmental tolerance.
• Leakage & Dissipation — Specified leakage current 1230 µA and tan δ 0.15 (measured at 20 °C, 120 Hz) to aid predictable loss and leakage budgeting.
• Regulatory Status — RoHS compliant material construction.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction in medium‑voltage power supplies where 250 V rating and high ripple capability are required.
• Industrial power electronics — Energy storage and decoupling in compact systems operating up to 105 °C and exposed to significant ripple currents.
• Equipment downsizing projects — Space‑constrained designs benefiting from the LGG series’ reduced case size compared with LGN.

Unique Advantages

• Space savings — One rank smaller case size enables reduced board real estate without sacrificing capacitance.
• Robust ripple handling — Combined low‑ and high‑frequency ripple ratings (1.5 A @120 Hz, 2.25 A @100 kHz) support mixed‑frequency power environments.
• High‑temperature endurance — 2000‑hour life at 105 °C provides predictable long‑term performance in hot operating environments.
• Predictable electrical characteristics — Specified tan δ and leakage current measured at standard conditions support accurate design margins.
• Secure PCB retention — Snap‑in terminal package minimizes mechanical stress and simplifies assembly for through‑hole mounting.
• RoHS compliance — Meets regulatory requirements for lead‑free assemblies.
