LGU2D681MELC

The LGU2D681MELC from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGU series, offered in mass production with tray packing. It provides 680 µF capacitance at a 200 V rating in a polarized, radial can snap-in package sized φ35 × 25 mm.

Designed for general-purpose applications, this capacitor delivers extended high-temperature endurance and measurable ripple handling for designs that require robust bulk capacitance in a compact snap-in form factor.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 200 V rated voltage and a capacitance tolerance of −20% to +20%.
• Snap-in Radial Package — Snap-in terminal, radial can package (φ35 × 25 mm) optimized for board-mounted installation; supplied in tray packing for production handling.
• High-Temperature Endurance — Rated for 3000 hours at 105°C when subjected to DC bias plus rated ripple current, meeting LGU series endurance specifications.
• Ripple Current Performance — Low-frequency ripple current of 1.78 A (120 Hz) and high-frequency ripple current of 2.67 A (50 kHz), with frequency-dependent coefficients per the LGU series.
• Loss & Leakage Characteristics — Tangent of loss angle (tanδ) of 0.15 measured at 20°C, 120 Hz; specified leakage current of 1100 µA.
• Wide Operating Temperature — Specified operating range from −40°C to 105°C for the 200 V rating.
• Regulatory Status — RoHS compliant as indicated in product data.

Typical Applications

• General Purpose — For designs requiring a 680 µF, 200 V polarized snap-in electrolytic capacitor with broad temperature capability and tray-packed supply.
• High-Temperature Endurance Use — Suitable where a capacitor must maintain characteristics after 3000 hours at 105°C under rated ripple and DC bias conditions.
• Compact Snap-In Assemblies — For assemblies that require a φ35 × 25 mm snap-in radial can with predictable ripple handling and leakage performance.

Unique Advantages

• Rated for 200 V systems — Enables use in higher-voltage general-purpose designs that require 680 µF bulk capacitance.
• Long endurance at elevated temperature — 3000 hours at 105°C ensures durability under sustained thermal stress and DC bias.
• Measured ripple capability — Defined low- and high-frequency ripple currents (1.78 A @120 Hz, 2.67 A @50 kHz) give clear design constraints for ripple handling.
• Defined loss and leakage specs — tanδ 0.15 (20°C, 120 Hz) and leakage current of 1100 µA provide verifiable electrical behavior for system-level modeling.
• Production-friendly packaging — Tray packing supports efficient handling in assembly and production environments.
• RoHS compliant — Conforms to applicable RoHS directive requirements as indicated in the product data.
