LGN2E681MELZ50

The LGN2E681MELZ50 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGN series, offering 680 µF capacitance at a 250 V rating. Designed as a smaller‑sized, high‑endurance snap‑in can, it targets general‑purpose power applications that require bulk capacitance, high ripple handling and extended life at elevated temperatures.

Key value comes from its combination of 680 µF capacitance, 250 V rating, rated ripple current capability and 3000‑hour endurance at 105°C, making it suitable for designs that demand reliable smoothing and energy storage in compact radial can packages.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 250 V and capacitance tolerance of −20% to +20%.
• Snap‑in Radial Can Package — Snap‑in terminal type in a compact φ22 × 50 mm can (L: 50 mm, D: 22 mm), provided in tray packing for production handling.
• High Temperature Endurance — Rated for operation from −40°C to +105°C with endurance of 3000 hours at 105°C under rated ripple conditions.
• Ripple Current Capability — Low‑frequency ripple current 1.7 A (120 Hz) and high‑frequency ripple current 2.55 A (100 kHz) to support AC ripple smoothing and decoupling.
• Leakage & Dissipation — Specified leakage current of 1230 µA and tangent of loss angle (tan δ) of 0.15 measured at 20°C, 120 Hz.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• General-purpose power supply filtering — Bulk smoothing and ripple reduction in power supplies where 680 µF at 250 V is required and where rated ripple currents and long endurance at 105°C are important.
• Industrial power electronics — Energy storage and decoupling in general industrial equipment designs that need a compact snap‑in radial can with proven high‑temperature life.
• High‑reliability assemblies — Use in assemblies requiring sustained ripple endurance (3000 hours at 105°C) and predictable leakage and loss characteristics for long service intervals.

Unique Advantages

• Extended ripple endurance: With a specified 3000‑hour life at 105°C under rated ripple, the LGN2E681MELZ50 supports longer service intervals in demanding thermal environments.
• Compact snap‑in form factor: The φ22 × 50 mm snap‑in can saves PCB space while providing robust mechanical mounting for high‑current assemblies.
• Clear performance data: Specified low‑frequency and high‑frequency ripple currents (1.7 A @120 Hz, 2.55 A @100 kHz), leakage current (1230 µA) and tan δ (0.15 @20°C,120 Hz) enable straightforward thermal and electrical design decisions.
• Wide operating temperature: −40°C to +105°C rating supports deployments across a broad thermal range without derating outside the specified limits.
• RoHS compliant and production ready: RoHS compliance and tray packing with mass production status streamline procurement and manufacturing integration.
