LGG2G331MELZ50

The LGG2G331MELZ50 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGG series. It delivers 330 µF capacitance at a 400 V rating in a compact φ22 × 50 mm radial can, designed for general‑purpose electronic equipment where reliable bulk capacitance and compact mounting are required.

Optimized for higher operating temperatures, the part is rated to 105°C with a 2000‑hour endurance at that temperature, and is supplied in tray packing for mass production use.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 400 V rated voltage and capacitance tolerance of ±20% (120 Hz, 20°C).
• High‑Temperature Operation — Rated for operation to 105°C with an endurance specification of 2000 hours at 105°C under DC bias plus rated ripple current.
• Snap‑In Radial Can — Snap‑in terminal, radial can package for secure board mounting and easy assembly in mass production (tray packing).
• Ripple Current Performance — Specified ripple current of 1.15 A at 120 Hz and 1.645 A at 100 kHz for effective smoothing in high‑stress applications.
• Low‑Temperature Stability — Impedance stability characterized down to −25°C with series data showing Z(−25°C)/Z(+20°C) ratios applicable to the 400 V range.
• Leakage and Loss Characteristics — Leakage current defined by I ≤ 3√(C·V) μA after 5 minutes at 20°C; tan δ limits per series specifications (≤0.15 for rated voltages up to 420 V at 120 Hz, 20°C).
• Polarized Design — Polar capacitor construction for DC applications requiring bulk energy storage and filtering.
• Regulatory — RoHS compliant.

Typical Applications

• General‑purpose electronic equipment — Bulk capacitance and smoothing where a 400 V rating and compact snap‑in mounting are required.
• Heat‑resilient systems — Applications that demand operation at elevated temperatures up to 105°C and proven 2000 h endurance at that temperature.
• Space‑constrained designs — Equipment downsizing where the LGG series’ ultra‑smaller case (one rank smaller than LGN) enables reduced board footprint.
• Production assemblies — Tray packing and snap‑in terminals suited to high‑volume assembly and stable mechanical mounting.

Unique Advantages

• Compact high‑voltage bulk capacitance: 330 µF at 400 V in a φ22 × 50 mm can provides substantial energy storage in a small footprint.
• High‑temperature endurance: 2000 hours at 105°C under rated conditions supports long‑term reliability in thermally demanding environments.
• Snap‑in mounting for production: Radial snap‑in terminals simplify PCB retention and are compatible with tray packing for mass production workflows.
• Measured ripple capability: Specified ripple currents at both 120 Hz and 100 kHz give designers clear targets for thermal and ripple handling in power circuits.
• Series‑level electrical limits provided: Defined leakage current formula and tan δ limits enable predictable design verification against series specifications.
• RoHS compliant: Meets RoHS requirements for environmentally conscious designs.
