LGU2P681MELC

The LGU2P681MELC is a snap‑in, radial can aluminum electrolytic capacitor in the Nichicon LGU series, rated 680 µF at 220 V. It is targeted at general‑purpose power applications that require high ripple handling, extended endurance at elevated temperature, and a compact snap‑in package for board mounting.

Key value comes from its rated 3000‑hour endurance at 105°C, specified ripple current capability across low and high frequencies, and a wide operating temperature range of −40°C to 105°C—making it suitable for sustained operation in commercial and industrial power systems.

Key Features

• Capacitance and Voltage — 680 µF nominal capacitance with a rated voltage of 220 V and tolerance of −20% to +20%, suitable for DC bus smoothing and energy storage in many power designs.
• High Temperature Endurance — Specified life of 3000 hours at 105°C under rated conditions, enabling long‑term operation in warm environments.
• Ripple Current Capability — Low frequency ripple current of 1.78 A at 120 Hz and high frequency ripple current of 2.67 A at 100 kHz, supporting effective ripple suppression across a broad frequency range.
• Leakage and Loss Characteristics — Leakage current specified at 1160 µA and tan δ (loss tangent) of 0.15 measured at 20°C, 120 Hz, providing measurable electrical behavior for design verification.
• Robust Operating Range — Operating temperature range from −40°C to 105°C for reliable performance across common commercial and industrial conditions.
• Package and Mounting — Snap‑in, radial can package (φ35 × 25L) designed for secure board retention and tray packing for production handling. RoHS compliant.

Typical Applications

• Industrial Power Supplies — Bulk filtering and DC bus stabilization where sustained ripple handling and high‑temperature endurance are required.
• Power Conversion and Inverters — Smoothing and energy buffering in converters and inverter stages that operate across a range of switching frequencies.
• UPS and Backup Systems — Energy storage and smoothing in backup power modules that demand long endurance at elevated temperatures.
• Commercial Electronics — General‑purpose decoupling and filtering in commercial equipment requiring a compact snap‑in can capacitor.

Unique Advantages

• Proven High‑Temperature Endurance: 3000 hours at 105°C offers designers a clearly specified life metric for thermal stress planning.
• Frequency‑Versatile Ripple Handling: Published ripple current ratings at 120 Hz and 100 kHz allow predictable performance across low and high switching frequencies.
• Compact Snap‑In Form Factor: φ35 × 25L radial can with snap‑in terminals delivers robust board retention while minimizing footprint.
• Measurable Electrical Parameters: Specified tan δ and leakage current values facilitate accurate thermal and leakage budgeting in system designs.
• RoHS Compliant and Production Ready: Tray packed and indicated as mass production status for supply chain readiness and assembly integration.
