LGU1C333MELB

The LGU1C333MELB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGU series, providing 33,000 µF capacitance at a 16 V rating. It’s a polarized, radial can style capacitor designed for general‑purpose power applications that require high bulk capacitance and robust ripple handling.

Key value comes from its 105°C endurance rating (3,000 hours), high ripple current capability across low and high frequencies, and tray packing for board‑level assembly. These attributes make it suitable where long life, temperature resilience, and high energy smoothing are required.

Key Features

• High Capacitance — 33,000 µF (33 mF) nominal capacitance for bulk energy storage and smoothing in power circuits.
• Voltage Rating — Rated at 16 V DC suitable for low‑voltage power rails.
• Wide Operating Temperature — −40°C to +105°C operating range to support elevated ambient environments.
• Endurance at Elevated Temperature — Rated life of 3,000 hours at 105°C while meeting specified capacitance, tan δ and leakage requirements after test conditions.
• High Ripple Current Handling — Low‑frequency ripple current 4.3 A (120 Hz) and high‑frequency ripple current 4.945 A (50 kHz) to handle significant AC stress on DC rails.
• Electrical Characteristics — Capacitance tolerance −20% to +20%; tangent of loss angle (tan δ) 0.50 measured at 20°C, 120 Hz for the 16 V rating; leakage current specified at 2,170 µA for this part.
• Package & Mounting — Snap‑in radial can (φ30 × 45 mm) for secure board mounting and straightforward installation; tray packing for handling and assembly.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power supply bulk smoothing — Large capacitance and high ripple current capability help stabilize low‑voltage DC rails and reduce voltage ripple in power supplies.
• Industrial power electronics — Designed to tolerate elevated temperatures (up to 105°C) and extended endurance for demanding industrial environments.
• Energy buffering in converters and inverters — High capacitance supports energy storage and filtering requirements in DC‑link and converter stages.

Unique Advantages

• Substantial bulk capacitance: 33,000 µF provides large energy storage in a compact φ30 × 45 mm can, helping reduce component count for bulk filtering.
• Robust ripple performance: Rated ripple currents of 4.3 A (120 Hz) and 4.945 A (50 kHz) enable reliable operation under significant AC loading.
• High‑temperature endurance: 3,000‑hour life at 105°C means predictable long‑term behavior in elevated ambient conditions.
• Snap‑in mounting for secure installation: Radial, snap‑in terminal simplifies board attachment and mechanical retention in high‑vibration environments.
• Measured electrical stability: Specified tan δ and leakage current limits provide verifiable loss and leakage characteristics for design margins.
• RoHS compliant and production ready: Tray packing and mass production status support prototyping through volume deployment while meeting environmental requirements.
