LGUW6680MELY

The LGUW6680MELY is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series, offering a 68 µF capacitance at a 420 V rating in a radial can package. Designed as a general‑purpose, high‑voltage electrolytic with snap‑in mounting, it addresses applications that require high ripple endurance and long operating life.

Key design attributes include a 3000‑hour endurance at 105 °C under rated ripple current, specified low and high frequency ripple current ratings, and a compact φ20×30L form factor supplied in tray packing for production volumes.

Key Features

• Voltage & Capacitance — 68 µF nominal capacitance with a 420 V rated voltage, suitable where high DC voltage capability is required.
• Endurance & Temperature — Rated for 3000 hours at 105 °C when subjected to rated ripple current; operating temperature range is −25 °C to 105 °C.
• Ripple Current Performance — Low frequency ripple current: 560 mA at 120 Hz; High frequency ripple current: 800.8 mA at 50 kHz, enabling effective smoothing under varying ripple conditions.
• Leakage Current — Specified leakage current of 500 µA, supporting stable performance after voltage application.
• Package & Mounting — Radial, snap‑in can (φ20×30L; L: 3 × D: 2 cm) for secure board mounting; supplied in tray packing and available for mass production.
• Polarized Design — Polarized electrolytic construction for DC bulk and filtering roles.
• RoHS Compliant — Meets RoHS requirements as specified for the LGU series.

Typical Applications

• General‑purpose power systems — Bulk capacitance and smoothing in systems that require a 420 V rated, long‑life electrolytic solution.
• Industrial power supplies — High ripple endurance and 105 °C rated life make it suitable for demanding power supply environments.
• DC bus filtering — Handles specified low‑ and high‑frequency ripple currents for DC link and bus stabilization tasks.

Unique Advantages

• High‑voltage capability: 420 V rating enables use in higher‑voltage DC circuits without stepping up component count.
• Proven thermal endurance: 3000 hours at 105 °C under rated ripple current demonstrates suitability for elevated‑temperature operating windows.
• Measured ripple handling: Distinct low‑ and high‑frequency ripple current specifications (560 mA @120 Hz; 800.8 mA @50 kHz) let designers quantify performance across frequency ranges.
• Compact snap‑in form factor: φ20×30L radial can with snap‑in terminals provides reliable PCB retention and streamlined assembly for production builds.
• Low leakage: 500 µA leakage current supports lower standby losses and predictable behavior after voltage application.
• Production ready: Tray packing and mass production status support scalable sourcing for volume designs.
