LGN2D681MELB25

The LGN2D681MELB25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGN series. It delivers 680 µF of capacitance at a 200 V rating in a compact radial can (φ30 × 25 mm) designed for general‑purpose electronic applications.

Built for elevated temperature operation, this part offers 3000 hours of endurance at 105°C and measurable high‑ and low‑frequency ripple handling, making it suitable where sustained bulk capacitance and long life are required.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 200 V and capacitance tolerance of −20% to +20%.
• High‑Temperature Endurance — Rated for operation from −40°C to 105°C with a guaranteed lifetime of 3000 hours at 105°C under rated ripple conditions.
• Ripple Current Capability — Low‑frequency ripple current of 1.75 A (120 Hz) and high‑frequency ripple current of 2.625 A (100 kHz), supporting circuits with significant AC content.
• Leakage & Dissipation — Specified leakage current of 1100 µA and tan δ (DF) up to 0.15 (measured at 20°C, 120 Hz), enabling predictable loss and leakage behavior.
• Package & Mounting — Snap‑in radial can (φ30 × 25 mm) for secure PCB mounting; supplied in tray packing for board‑level handling.
• Regulatory — RoHS compliant.
• Series Advantage — Part of the LGN series, which is specified as a smaller‑sized snap‑in option within its family while maintaining 105°C, long‑life performance.

Typical Applications

• General‑purpose power filtering — Use where 680 µF at 200 V bulk capacitance is required for smoothing and energy storage in general‑purpose electronics.
• High‑temperature systems — Suited to equipment that must maintain capacitance and reliability at up to 105°C for extended periods (3000 h endurance).
• High‑ripple circuits — Appropriate where elevated ripple currents occur, with specified performance at both 120 Hz and 100 kHz.

Unique Advantages

• Long, specified lifetime: 3000 hours at 105°C ensures predictable end‑of‑life performance for designs requiring long‑term stability.
• Dual‑band ripple handling: Rated ripple values at 120 Hz and 100 kHz allow engineers to size the capacitor for both mains‑frequency and high‑frequency ripple conditions.
• Compact snap‑in packaging: φ30 × 25 mm radial can with snap‑in terminals provides secure PCB mounting in a smaller case footprint relative to some family members.
• Measured loss and leakage specs: Clear tan δ and leakage current values (0.15 and 1100 µA respectively) make it straightforward to predict thermal loss and standby leakage in designs.
• RoHS compliance: Meets environmental regulations for restricted substances as listed in the product data.
