LGU1J332MELB

The LGU1J332MELB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series. It provides 3.3 mF (3300 µF) capacitance at a 63 V rating in a φ30 × 30 mm can designed for snap‑in mounting and tray packing.

Engineered for general‑purpose power applications, this part delivers sustained ripple handling and long endurance at elevated temperature, making it suitable for designs that require reliable bulk energy storage and smoothing at up to 105 °C.

Key Features

• Electrical Capacity — 3300 µF nominal capacitance with tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Rated Voltage — 63 V DC rating for mid‑voltage power applications.
• High Ripple Current Handling — Rated low‑frequency ripple current of 2.24 A at 120 Hz and high‑frequency ripple current of 2.576 A at 50 kHz.
• Loss Characteristics — tan δ (DF) max 0.25 measured at 120 Hz, 20 °C, enabling predictable dissipation behavior.
• Leakage Current — Specified leakage current of 1360 µA after rated voltage application at 20 °C.
• Endurance at Elevated Temperature — Designed to withstand 3000 hours of rated ripple current and DC bias at 105 °C per LGU series endurance specification.
• Operating Temperature Range — −40 °C to +105 °C for broad environmental tolerance.
• Package and Mounting — Snap‑in radial can (φ30 × 30 mm) for secure through‑hole mounting; supplied in tray packing for handling and assembly.
• Environmental Compliance — RoHS‑compliant construction.
• Polarized — Requires correct polarity during installation.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and ripple reduction where a 63 V, 3300 µF capacitor is required.
• Power supply energy storage — Local energy reservoir for mid‑voltage DC rails operating up to 105 °C.
• Industrial and commercial equipment — Reliable bulk capacitance for systems that require sustained ripple performance and long endurance.

Unique Advantages

• Sustained ripple endurance — Rated for 2.24 A (120 Hz) and 2.576 A (50 kHz) ripple currents to support continuous AC ripple on DC lines.
• Long high‑temperature life — 3000 hours endurance at 105 °C under rated conditions for extended service in thermally demanding environments.
• Practical snap‑in format — Radial snap‑in can simplifies board mounting and secures the part against vibration and handling.
• Clear electrical specification — Measured tan δ and leakage current values provide predictable dissipation and leakage behavior for design verification.
• RoHS compliance — Meets regulatory requirements for lead‑free assembly environments.
