LGU2A332MELC

The LGU2A332MELC from Nichicon is a snap‑in, polarized aluminum electrolytic capacitor providing 3.3 mF (3300 µF) at 100 V in a radial can package. It is part of the LGU series designed for general‑purpose power applications that require sustained performance at elevated temperatures.

Key value comes from its long endurance rating—3000 hours at 105°C—combined with rated ripple current capability and a compact φ35 × 40 mm can, making it suitable where reliable bulk capacitance and thermal endurance are required.

Key Features

• Core Electricals — 3.3 mF (3300 µF) capacitance with a tolerance of −20% to +20% and polarized construction for DC bulk storage and filtering.
• Rated Voltage — 100 V nominal rating suitable for higher‑voltage power rails within general‑purpose systems.
• Ripple Current Performance — Low‑frequency ripple current of 3.31 A at 120 Hz and high‑frequency ripple current of 3.8065 A at 50 kHz, specified for reliable ripple handling across frequencies.
• Loss and Leakage — Dissipation factor (tanδ) of 0.2 measured at 20°C, 120 Hz, and a specified leakage current of 1720 µA.
• Thermal and Endurance — Operating range −40°C to +105°C with an endurance rating of 3000 hours at 105°C under rated ripple and DC bias conditions.
• Package & Mounting — Snap‑in radial can (φ35 × 40 mm) for secure PCB mounting; supplied in tray packing for production assembly.
• Compliance & Availability — RoHS‑compliant and listed as mass production status within the Nichicon LGU series.

Typical Applications

• Power supply smoothing and filtering — Provides bulk capacitance and ripple handling for DC link and output smoothing on high‑voltage rails up to 100 V.
• DC link / energy storage — 3.3 mF capacitance combined with rated ripple current and 105°C endurance supports short‑term energy buffering in power stages.
• Industrial and general‑purpose power electronics — Specified for −40°C to +105°C operation and 3000‑hour endurance at 105°C, suitable for designs that demand sustained thermal reliability.
• High‑voltage bulk decoupling — Polarized, high‑capacitance option for decoupling and bulk storage on 100 V rails in a compact snap‑in package.

Unique Advantages

• Extended thermal endurance: 3000 hours at 105°C ensures stable performance under prolonged elevated‑temperature conditions.
• High working voltage and bulk capacitance: 100 V rating with 3.3 mF (3300 µF) supports higher‑voltage power designs that require large capacitance values.
• Frequency‑versatile ripple handling: Ripple current ratings specified at both 120 Hz (3.31 A) and 50 kHz (3.8065 A) provide predictable performance over a broad frequency range.
• Measured loss and leakage metrics: tanδ = 0.2 (20°C, 120 Hz) and leakage current = 1720 µA enable designers to quantify dissipation and standby loss for power‑budget calculations.
• Production‑friendly packaging and mounting: Snap‑in radial can and tray packing streamline board insertion and handling for assembly workflows.
• RoHS compliance and series support: Conforms to RoHS requirements and is available as part of the Nichicon LGU series in mass production.
