LGU2D681MELZ

The LGU2D681MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series. It provides 680 µF capacitance at a 200 V rating in a radial, can‑snap‑in package sized φ22 × 45 mm.

Engineered for general‑purpose applications, this part delivers high operating temperature capability (–40 °C to 105 °C), a rated endurance of 3000 hours at 105 °C, and robust ripple handling up to 2.67 A at high frequency, making it suitable for demanding power‑conditioning roles in commercial and industrial equipment.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 200 V rated voltage and tolerance of −20% to +20% for bulk energy storage and DC link applications.
• High‑temperature Endurance — Specified lifetime of 3000 hours at 105 °C when exposed to rated ripple and DC bias, supporting extended operation in elevated temperature environments.
• Ripple Current Performance — Low frequency ripple current 1.78 A at 120 Hz and high frequency ripple current 2.67 A at 50 kHz, with frequency coefficients defined in the LGU series datasheet.
• 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 dissipation and self‑discharge behavior.
• Mechanical & Mounting — Snap‑in radial can package (φ22 × 45 mm) designed for secure board mounting and tray packing for production handling.
• Regulatory Compliance — RoHS compliant per the product data.

Typical Applications

• General‑purpose power systems — Provides bulk capacitance and filtering where 680 µF at 200 V is required for DC smoothing and intermediate storage.
• Industrial electronics — Suitable for equipment designs that require operation to 105 °C and long endurance (3000 hours) under rated ripple and bias conditions.
• Power assemblies and rack modules — Snap‑in radial can package and tray packing facilitate mechanical mounting and production assembly in power modules and panels.

Unique Advantages

• High‑voltage bulk capacitance: 680 µF at 200 V supplies substantial stored energy for DC link and smoothing uses without upsizing the enclosure.
• Designed for high temperature operation: Rated to −40 °C to 105 °C with a 3000‑hour endurance at 105 °C, supporting designs exposed to sustained elevated temperatures.
• Defined ripple performance across frequencies: Published ripple current values (1.78 A at 120 Hz, 2.67 A at 50 kHz) and frequency coefficients allow engineers to size capacitors confidently for low and high frequency ripple environments.
• Predictable electrical behavior: Specified tan δ and leakage current values enable clear thermal and leakage budgeting during design validation.
• Production‑friendly packaging: Snap‑in terminal and tray packing streamline placement and handling in high‑volume assembly processes.
