LGGW6331MELA45

The LGGW6331MELA45 is a snap‑in, aluminum electrolytic capacitor from Nichicon’s LGG series, specified at 330 µF and 420 V with a 105°C maximum operating temperature. Designed for general‑purpose use, this radial can (snap‑in) package provides a compact high‑voltage capacitance option for equipment requiring bulk energy storage and ripple handling.

Offered in tray packing for mass production, the part combines elevated temperature endurance with a small footprint (φ25 × 45 mm), RoHS compliance, and snap‑in mounting for secure board retention and straightforward assembly.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 420 V for high‑voltage bulk energy storage in general‑purpose circuits.
• High Temperature Rating — 105°C maximum operating temperature with an endurance specification of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Snap‑in Radial Package — Radial, can‑type snap‑in terminals for secure mechanical mounting and efficient PCB assembly; tray packing supports production workflows.
• Polarized Electrolytic — Polarized construction suitable for DC smoothing and filtering applications.
• Leakage Current Specification — Leakage current defined by I ≤ 3√(C·V) μA after 5 minutes’ application of rated voltage at 20°C.
• Frequency & Ripple Handling — Rated ripple current: 1.35 A at 120 Hz (low frequency) and 1.931 A at 100 kHz (high frequency).
• Low‑temperature Stability (420 V class) — Impedance ratio Z(–25°C)/Z(+20°C) up to 8, indicating defined impedance behavior down to –25°C for 400–450 V parts.
• Tolerance & Marking — Capacitance tolerance ±20% (–20% to +20%); sleeve marked with white text on black for identification.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• General‑Purpose Power Filtering — Bulk smoothing and decoupling where a 420 V, 330 µF polarized capacitor is required.
• High‑Voltage DC Bus Support — Energy storage and ripple suppression on DC rails that operate up to 420 V.
• Production‑Ready Modules — Tray packing and snap‑in mounting streamline integration into mass production assemblies.

Unique Advantages

• High Voltage Capacity: 420 V rating combined with 330 µF capacitance provides substantial energy density for high‑voltage rail applications.
• Compact Snap‑in Form Factor: φ25 × 45 mm can size in a snap‑in radial package balances board space savings with robust mechanical retention.
• Elevated Temperature Endurance: Specified 2000 hours at 105°C under rated conditions, offering predictable aging and long‑term performance at high temperature.
• Defined Leakage & Loss Limits: Leakage current governed by I ≤ 3√(C·V) μA and tan δ max 0.15 at rated voltage (for 160–420 V), enabling predictable electrical behavior.
• Wide Operating Temperature Window: Rated for –25°C to +105°C at 400–450 V, supporting designs that encounter moderate cold‑start and elevated operating temperatures.
• Production Friendly: Tray packing and snap‑in terminals simplify automated assembly and high‑volume manufacturing workflows.
