LGU2F821MELC

The LGU2F821MELC is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, designed for general‑purpose power applications requiring high voltage and sustained ripple handling. It delivers 820 µF capacitance at a 315 V rating with snap‑in mounting in a φ35 × 45 mm can and is supplied in tray packing.

Engineered for continuous operation up to 105°C with a proven 3000‑hour endurance at rated ripple current, this capacitor targets industrial and commercial power systems where reliable smoothing, filtering and energy buffering at elevated voltage are required.

Key Features

• Rated Performance — 820 µF capacitance at 315 V rated voltage with a capacitance tolerance of −20% to +20%.
• High Temperature Endurance — Rated lifetime of 3000 hours at 105°C when subjected to rated ripple current and DC bias.
• Ripple Current Capability — Low‑frequency ripple current 2.2 A (120 Hz) and high‑frequency ripple current 3.146 A (50 kHz), enabling effective smoothing across frequency ranges.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) 0.15 measured at 20°C, 120 Hz, and typical leakage current specified at 1,520 µA after 5 minutes at rated voltage.
• Robust Mechanical Package — Snap‑in terminal, radial can package (φ35 × 45 mm) for secure PCB mounting and straightforward assembly; supplied in tray packing for production handling.
• Operating Range and Compliance — Rated for −25°C to +105°C operation and compliant with RoHS directives.
• Polarized Design — Polarized aluminum electrolytic suitable for DC power applications requiring polarity awareness.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and filtering in high‑voltage power supplies and control systems where 315 V ratings and sustained ripple performance are needed.
• Inverters and Motor Drives — DC link and energy buffering roles in inverter and motor drive circuitry that require durable operation at elevated temperatures.
• Uninterruptible Power Supplies (UPS) and Energy Storage — Capacitance and ripple handling for intermediate energy storage and output stabilization in UPS modules and power conversion chains.
• Commercial Power Conversion — Filtering and decoupling in commercial converters and equipment that operate at higher DC voltages and require tray‑friendly components for assembly.

Unique Advantages

• High‑voltage capability: 315 V rating enables use in higher DC bus and power conversion designs without series stacking.
• Long high‑temperature life: 3000 hours at 105°C under rated ripple current supports designs with elevated ambient or loading conditions.
• Wide ripple frequency support: Specified ripple current at both 120 Hz and 50 kHz provides predictable performance across low and high frequency filtering tasks.
• Compact, production‑friendly package: φ35 × 45 mm snap‑in can in tray packing simplifies mechanical mounting and board population for high‑volume manufacturing.
• Measurable electrical characteristics: Specified tan δ (0.15 at 20°C/120 Hz) and quantified leakage current (1,520 µA) allow designers to model losses and standby current precisely.
• RoHS compliant: Meets RoHS requirements for regulated material content in commercial and industrial products.
