LGU2A102MELA

The LGU2A102MELA from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGU series, rated 100 V and 1000 µF with ±20% tolerance. Designed for general‑purpose power applications, it combines high operating temperature capability and extended endurance for demanding industrial and commercial designs.

Key electrical characteristics include a 105°C maximum operating temperature, low‑loss performance (tan δ = 0.2 at 20°C, 120 Hz), specified low‑frequency and high‑frequency ripple current capability, and a 3000‑hour endurance at 105°C under rated conditions.

Key Features

• Rated Capacitance & Voltage — 1000 µF at 100 V with ±20% tolerance, providing bulk energy storage and decoupling in higher‑voltage circuits.
• High Temperature Endurance — Specified lifetime of 3000 hours at 105°C when subjected to rated ripple current, supporting sustained operation in elevated ambient conditions.
• Ripple Current Performance — 1560 mA at 120 Hz (low frequency) and 1794 mA at 50 kHz (high frequency), enabling effective filtering across a range of switching and line frequencies.
• Low Loss (tan δ) — Tangent of loss angle 0.2 at 20°C/120 Hz for the 100 V rating, indicating controlled dissipation in AC conditions.
• Leakage Current — 940 µA specified, allowing designers to account for off‑state current in bias and standby calculations.
• Snap‑In Radial Can Package — φ25 × 30 mm can with snap‑in terminals for secure board mounting and high mechanical robustness; supplied in tray packing for mass production.
• Wide Operating Temperature — −40°C to +105°C operating range suitable for a variety of environmental conditions.
• Regulatory — RoHS compliant.

Typical Applications

• Power Supply Filtering — Bulk smoothing and filter stages in industrial and commercial power supplies, leveraging 1000 µF capacitance and specified ripple current ratings.
• DC‑Link and Energy Storage — DC‑link decoupling in power conversion and inverters where 100 V rating and high ripple endurance are required.
• Switching Power Electronics — Support for switching converters and motor drive front‑ends where both low‑loss behavior and high ripple current capability are important.

Unique Advantages

• Extended High‑Temperature Life: 3000 hours at 105°C under rated ripple current reduces the need for frequent capacitor replacement in high‑temperature installations.
• Versatile Ripple Handling: Measured ripple current values at both low and high frequencies enable reliable smoothing across different switching regimes.
• Clear, Verifiable Electricals: Specified tan δ, leakage current and tolerance values allow precise thermal and leakage budgeting during design.
• Robust Mounting: Snap‑in radial can with tray packing supports secure PCB mounting and efficient assembly for production runs.
• Compliance: RoHS status provided to support regulatory assessment and procurement requirements.
