LGU2C331MELY

The LGU2C331MELY is an aluminum electrolytic capacitor from Nichicon's LGU series in a snap‑in terminal can. It provides 330 µF capacitance at a 160 V rating and is supplied in tray packing for ready integration.

Designed for general‑purpose applications, the device delivers high ripple current capability (1.2 A at 120 Hz, 1.8 A at 50 kHz) and 3000 hours of endurance at 105 °C, supporting reliable operation across a −40 °C to 105 °C temperature range.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 160 V rated voltage and ±20% tolerance.
• High Ripple Current Handling — Low‑frequency ripple current 1.2 A at 120 Hz and high‑frequency ripple current 1.8 A at 50 kHz to support demanding power conditions.
• Endurance at Elevated Temperature — Qualified for 3000 hours of rated ripple current application at 105 °C per LGU series endurance specification.
• Loss Characteristics — tan δ (DF) specified at 0.15 (measured at 20 °C, 120 Hz) to characterize dissipation.
• Leakage Current — Specified leakage current of 680 µA (measured per product data conditions).
• Robust Operating Range — Polarized device rated for operation from −40 °C to 105 °C.
• Snap‑In Package — Radial, can-style snap‑in mounting for secure board or module installation; physical size φ20 × 30 mm (L: 3 × D: 2 cm).
• Regulatory — RoHS‑compliant construction.

Typical Applications

• General‑purpose power modules — Provides bulk capacitance and ripple handling for power modules requiring 160 V rated components and 105 °C endurance.
• Power supply filtering — 330 µF capacitance and high ripple current capability support smoothing and filtering in power supply circuits.
• High‑temperature endurance environments — Rated for 3000 hours at 105 °C for designs that require prolonged elevated‑temperature operation.

Unique Advantages

• High ripple current capacity: 1.2 A at 120 Hz and 1.8 A at 50 kHz reduce thermal stress in high‑ripple applications.
• Long endurance at 105 °C: 3000‑hour qualification ensures predictable performance under continuous high‑temperature loading.
• Compact snap‑in form factor: φ20 × 30 mm can with snap‑in terminals simplifies mechanical integration into power assemblies.
• Measured dissipation factor: tan δ 0.15 at 20 °C, 120 Hz provides a quantified loss parameter for thermal and ripple analysis.
• RoHS compliant: Environmentally compliant construction for global product designs.
• Tray packing: Supplied in trays to support handling and automated assembly processes.
