LGGW6331MELC30

The LGGW6331MELC30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGG series. It delivers 330 µF at a rated voltage of 420 V in a compact radial can snap‑in package designed for space‑constrained equipment.

Targeted at general‑purpose electronic designs, this part combines high voltage capability, elevated operating temperature (–25°C to 105°C), and long endurance (2000 hours at 105°C) to support demanding power applications and downsized equipment layouts.

Key Features

• Capacitance and Voltage — 330 µF rated capacitance at 420 V for high‑voltage applications.
• Snap‑in Radial Package — Snap‑in terminal type in a φ35 × 30 mm can for secure board mounting and compact footprint.
• Wide Operating Temperature — Rated for −25°C to +105°C, enabling operation in elevated ambient conditions.
• Endurance — 2000 hours at 105°C under rated conditions, with specified limits for capacitance change, dissipation factor, and leakage current after endurance testing.
• Low Loss — Tangent of loss angle (tan δ) specified at 0.15 (max.) measured at 20°C, 120 Hz for 160–420 V ratings.
• High Ripple Current Capability — 1.42 A (120 Hz) low‑frequency ripple and 2.031 A (100 kHz) high‑frequency ripple current ratings support smoothing under AC and switching conditions.
• Leakage Current — Specified leakage of 1110 µA after voltage application at 20°C.
• RoHS Compliant & Mass Production — Compliant with RoHS requirements and supplied in tray packing with mass production status.

Typical Applications

• General‑purpose electronic equipment — For designs requiring high voltage smoothing and bulk capacitance in a snap‑in radial package.
• Space‑constrained systems — Suited for equipment downsizing where a smaller case size is required while maintaining 420 V capability.
• High‑temperature environments — Applicable where operation up to 105°C and long endurance (2000 h) are required.

Unique Advantages

• High voltage handling: 420 V rating provides margin for high‑voltage circuits without increasing capacitance size.
• Compact snap‑in form factor: φ35 × 30 mm radial can with snap‑in terminals enables robust PCB mounting and efficient use of board space.
• Designed for elevated temperatures: Rated to 105°C with a 2000‑hour endurance specification for sustained high‑temperature operation.
• Strong ripple performance: 1.42 A @120 Hz and 2.031 A @100 kHz ripple ratings support both low‑ and high‑frequency power smoothing needs.
• Controlled dielectric loss: tan δ specified at 0.15 (max.) at 20°C/120 Hz, aiding predictable performance in AC applications.
• Regulatory compliance and production readiness: RoHS compliant and available in tray packing, with mass production status to support volume deployment.
