LGU2E331MELY

The LGU2E331MELY from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGU series, offering 330 µF capacitance at a 250 V rating. Designed for general-purpose power applications, it combines high ripple-handling capability with extended endurance at elevated temperatures.

Built for applications that require robust smoothing and decoupling performance, this snap-in radial can supports high-frequency and low-frequency ripple currents while operating across a broad temperature range up to 105°C.

Key Features

• Electrical Performance — 330 µF capacitance with ±20% tolerance at 120 Hz, 20°C; rated voltage 250 V.
• Ripple Current Capability — Low-frequency ripple current 1.2 A at 120 Hz and high-frequency ripple current 1.8 A at 50 kHz, enabling effective smoothing in power circuits.
• Loss and Leakage — Tangent of loss angle (tan δ) 0.15 (measured at 20°C, 120 Hz) and leakage current 860 µA, supporting predictable ESR-related behavior and standby characteristics.
• Temperature and Endurance — Operating temperature range −40°C to 105°C with a rated endurance of 3000 hours at 105°C under rated ripple current conditions.
• Mechanical & Mounting — Snap-in radial can package (φ20 × 40 mm / L: 4 cm × D: 2 cm) for secure PCB mounting; supplied in tray packing and available in mass production quantities.
• Regulatory — RoHS compliant.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where 250 V rating and high ripple current capability support stable voltage regulation.
• Industrial Power Systems — Energy storage and decoupling in industrial controllers and power racks that operate across −40°C to 105°C and require long endurance at elevated temperature.
• Inverters and Motor Drives — DC link smoothing and ripple absorption where high-frequency and low-frequency ripple performance improve system reliability.
• Backup Power and UPS — Bulk capacitance for short-term energy buffering and voltage stabilization under continuous ripple load conditions.

Unique Advantages

• High Ripple Endurance: Rated for 1.2 A at 120 Hz and 1.8 A at 50 kHz, enabling effective handling of both mains-frequency and switching-frequency ripple loads.
• Extended High-Temperature Life: Qualified for 3000 hours at 105°C under rated ripple conditions, providing predictable long-term performance in hot environments.
• Compact Snap-In Form Factor: φ20 × 40 mm radial snap-in can simplifies PCB assembly and secures mechanical stability for vertical mounting.
• Controlled Dissipation: Low tan δ (0.15 at 20°C, 120 Hz) ensures controlled losses and thermal behavior in power applications.
• RoHS Compliant and Production-Ready: Environmentally compliant construction and tray packing for streamlined procurement and assembly workflows.
