LGNW6331MELB35

The LGNW6331MELB35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGN series, offering 330 µF capacitance at a 420 V rating. Designed as a large‑can, radial snap‑in package (φ30 × 35 mm), it targets general‑purpose applications that require high voltage bulk capacitance and robust thermal endurance.

Key value propositions include a 105°C operating rating with 3000 hours endurance, high ripple current capability at both low and high frequencies, and RoHS compliance—making it suitable for demanding power environments where long life and reliable filtering are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 420 V rated voltage, suitable where high DC bulk capacitance is required.
• Temperature & Endurance — Rated for –25°C to 105°C with an endurance specification of 3000 hours at 105°C when subjected to rated ripple current.
• High Ripple Current Handling — Low‑frequency ripple current of 1.42 A (120 Hz) and high‑frequency ripple current of 2.031 A (100 kHz) to support continuous ripple stress.
• Insulation & Loss — Tangent of loss angle (tan δ) of 0.15 measured at 20°C, 120 Hz (applicable at rated voltages up to 420 V).
• Leakage Current — Specified leakage current of 1110 µA after rated voltage application test conditions.
• Package & Mounting — Snap‑in terminal radial can, compact φ30 × 35 mm size, supplied in tray packing for assembly handling.
• Compliance & Availability — RoHS compliant and listed as mass production status.

Typical Applications

• General Purpose — Intended for general‑purpose circuits requiring 420 V, 330 µF bulk capacitance with snap‑in mounting.
• High‑Temperature Environments — Suitable where continuous operation up to 105°C and 3000 hours endurance are required.
• Tray‑Packed Assemblies — Tray packing and snap‑in terminals facilitate integration into rack or chassis assemblies that accept radial can components.

Unique Advantages

• High Voltage Bulk Capacitance: 420 V rating combined with 330 µF provides substantial stored energy for DC bus and smoothing applications.
• Long Endurance at Elevated Temperature: Specified for 3000 hours at 105°C under rated ripple current, supporting extended service life in thermally stressed designs.
• Dual‑Frequency Ripple Capability: Defined ripple currents at 120 Hz and 100 kHz enable designers to assess performance across both low and high frequency stress conditions.
• Compact Snap‑In Form Factor: φ30 × 35 mm radial can with snap‑in terminals offers a space‑efficient solution for chassis and power module mounting.
• Predictable Loss and Leakage: tan δ specified at 0.15 (20°C, 120 Hz) and a defined leakage current allow accurate thermal and loss budgeting.
• RoHS Compliant & Production‑Ready: Compliant to RoHS and available in mass production quantities for consistent supply.
