LGU1H822MELC

The LGU1H822MELC from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGU series, rated 50 V with 8200 μF (8.2 mF) capacitance and ±20% tolerance. It is designed for general‑purpose power applications that require high ripple capability, robust endurance and a compact radial can package.

Key value comes from high ripple current ratings at multiple frequencies, long endurance at elevated temperature (3000 hours at 105°C), and a snap‑in mounting style that supports secure, production‑friendly assembly and tray packing for mass production.

Key Features

• Capacitance & Voltage: 8200 μF nominal capacitance at a 50 V rating with ±20% tolerance, suitable where substantial bulk capacitance is required.
• High Ripple Current Capability: Rated ripple current of 3.660 A at 120 Hz (low frequency) and 4.209 A at 50 kHz (high frequency), supporting demanding power‑filtering and smoothing tasks.
• Endurance and Thermal Performance: Specified 3000 hours life at 105°C; designed to meet endurance requirements when exposed to rated DC bias plus rated ripple at elevated temperature.
• Leakage and Dissipation: Leakage current specified at 1920 μA and tangent of loss angle (tan δ) of 0.30 measured at 20°C and 120 Hz, providing defined dissipation characteristics for thermal and loss budgeting.
• Mounting & Package: Snap‑in terminal (radial can, snap‑in) for secure board mounting and simplified mechanical retention in high‑vibration or production environments; supplied in tray packing for mass production handling.
• Operating Range & Size: Operating temperature −40°C to +105°C; compact footprint with diameter φ35 mm and length 35 mm (L: 3.5 × D: 3.5 cm).
• Compliance: RoHS compliant as part of the LGU series.

Typical Applications

• Power supply bulk smoothing: Bulk energy storage and smoothing in power supplies where large capacitance and high ripple handling are required.
• DC link and converter support: Filtering and ripple absorption in DC‑DC converters and AC‑DC power stages operating up to 50 V.
• Industrial and consumer power electronics: General‑purpose use in industrial controls, power modules, and consumer power systems that need long‑life, high‑ripple capacitors.

Unique Advantages

• Designed for sustained ripple duty: High specified ripple currents at both low and high frequencies reduce thermal stress and support reliable operation in high‑ripple circuits.
• Long elevated‑temperature life: 3000‑hour rating at 105°C provides predictable lifetime behavior in high‑temperature environments and supports longer maintenance intervals.
• Production‑friendly package: Snap‑in radial can and tray packing streamline installation and automated assembly for volume manufacturing.
• Clear electrical characterization: Defined leakage current and tan δ values (1920 μA leakage, tan δ 0.30 at 20°C/120 Hz) simplify thermal and loss calculations during design.
• RoHS compliance: Meets environmental directive requirements for restricted substances as specified for the LGU series.
