LGU2E331MELZ

The LGU2E331MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series. It provides 330 µF of capacitance at a 250 V rating in a radial, snap‑in can designed for general‑purpose electronic equipment.

Engineered for sustained operation at elevated temperature, this part offers high ripple current capability and a 3000‑hour endurance rating at 105°C, making it suitable for applications that require stable bulk capacitance and reliable long‑term performance.

Key Features

• Rated Capacitance & Voltage — 330 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• Low Loss Characteristic — Tangent of loss angle (tan δ) of 0.15 maximum at 120 Hz and 20°C for the 250 V rating, supporting efficient energy handling.
• High Ripple Current Capability — Supports 1.3 A ripple current at 120 Hz and 1.95 A at 50 kHz, enabling robust performance under AC ripple conditions.
• Leakage Current — Specified leakage current of 860 µA, providing predictable standby behavior after voltage application.
• Temperature & Endurance — Operates from −40°C to +105°C with a guaranteed endurance of 3000 hours at 105°C under rated ripple and DC bias.
• Package & Mounting — Snap‑in radial can, size φ22 × 40 mm (D×L), designed for stable board mounting and high‑current power applications; supplied in tray packing for production use.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General‑Purpose Power Supplies — Bulk smoothing and filtering for 250 V systems where stable capacitance and high ripple handling are required.
• Power Conversion Modules — Energy storage and ripple suppression in equipment operating within the −40°C to +105°C range and requiring long endurance at elevated temperature.
• Industrial Electronic Equipment — Reliable bulk capacitance for control and power electronics in general‑purpose industrial applications.

Unique Advantages

• Long High‑Temperature Endurance — 3000 hours rated life at 105°C supports longer service intervals and predictable aging under continuous high‑temperature operation.
• Wide Operating Temperature Range — −40°C to +105°C operation makes the part suitable for a broad range of environments without derating thermal performance.
• Robust Ripple Handling — Specified ripple currents at both low (120 Hz) and high (50 kHz) frequencies enable use in applications with mixed ripple spectra.
• Compact Snap‑in Form Factor — φ22 × 40 mm radial snap‑in can offers a space‑efficient solution for board‑level bulk capacitance needs while simplifying assembly.
• Predictable Loss and Leakage — Defined tan δ and leakage current figures allow designers to model power loss and standby behavior accurately.
• Production‑Ready Supply — Tray packing and mass production status facilitate reliable procurement for volume manufacturing.
