LGU2F331MELB

The LGU2F331MELB is a Nichicon LGU series aluminum electrolytic capacitor with a snap‑in terminal design, rated at 330 µF and 315 V. It is intended for general‑purpose electronic applications that require a high‑voltage electrolytic capacitor in a radial can / snap‑in package.

Designed for continuous operation up to 105°C, this part offers specified ripple current capability and endurance characteristics for demanding thermal and ripple environments where a 315 V, 330 µF polarized capacitor is required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 315 V rated DC voltage and ±20% tolerance at 20°C, 120 Hz.
• High‑temperature Endurance — Rated endurance of 3000 hours at 105°C with specified DC bias plus rated ripple current applied.
• Ripple Current Performance — Low frequency ripple current of 1.33 A at 120 Hz and high frequency ripple current of 1.902 A at 50 kHz, enabling effective ripple handling within specified limits.
• Low Loss — Tangent of loss angle (tan δ) specified at 0.15 (max) for 160 to 420 V range measured at 120 Hz, 20°C, consistent with the 315 V rating.
• Leakage Current — Rated leakage current of 960 µA (I ≤ 3 CV µA after 5 minutes at 20°C as per series specification methodology).
• Operating Temperature Range — Specified for operation from −25°C to +105°C for the 315 V product family.
• Package & Mounting — φ30 × 30 mm can with snap‑in radial terminals, supplied in tray packing for mass production use.
• RoHS Compliant — Manufactured in compliance with RoHS requirements as stated for the LGU series.

Typical Applications

• General‑purpose electronic circuits — Suitable where a 315 V, 330 µF polarized electrolytic capacitor in a snap‑in can is required for board assembly.
• Power electronics modules — Used in circuits that require DC bus capacitance and specified ripple handling at elevated temperatures.
• Industrial equipment assemblies — Appropriate for production environments that utilize tray packing and snap‑in mounting for secure installation.

Unique Advantages

• High‑voltage capability: 315 V rating provides substantial DC voltage margin for designs requiring elevated voltage electrolytic capacitance.
• Extended endurance at 105°C: 3000 hours rated life under rated ripple and DC bias supports reliability in thermally demanding applications.
• Clearly specified ripple performance: Distinct low‑ and high‑frequency ripple current values (1.33 A at 120 Hz, 1.902 A at 50 kHz) allow engineers to match the capacitor to expected ripple environments.
• Compact snap‑in form factor: φ30 × 30 mm radial can with snap‑in terminals simplifies secure PCB mounting in mass production workflows.
• Measurable leakage and loss characteristics: Defined leakage current and tan δ limits enable predictable electrical behavior and easier design verification.
