LGJ2E331MELB20

The LGJ2E331MELB20 is an aluminum electrolytic, snap-in terminal capacitor in Nichicon’s LGJ series designed for general-purpose power applications. It combines a 330 µF capacitance with a 250 V rating in a low-profile, radial can snap-in package optimized for mass-production assemblies.

Key value propositions include high-temperature endurance (3000 hours at 105 °C), defined ripple current capability across frequency, and a compact φ30×20 mm footprint for space-constrained designs.

Key Features

• Capacitance & Tolerance — 330 µF with ±20% tolerance at 120 Hz, 20 °C, providing a specified stored charge in high-voltage circuits.
• Rated Voltage — 250 V DC rating suitable for higher-voltage general-purpose power applications.
• Snap-in Terminal / Package — Radial, can-type snap-in mounting for robust PCB attachment in production assemblies.
• Low-Profile Size — Dimensions φ30 × 20 mm (D × L) for compact placement in enclosures with limited axial space.
• High-Temperature Endurance — 3000 hours life at 105 °C, supporting long-term operation under elevated ambient conditions.
• Operating Temperature Range — Rated from −40 °C to +105 °C for broad environmental tolerance.
• Ripple Current Performance — Rated ripple current of 1.08 A at 120 Hz (low frequency) and 1.62 A at 50 kHz (high frequency); series frequency coefficients indicate increased allowable ripple at higher frequencies.
• Leakage Current — Specified leakage current of 860 µA after rated-voltage application and stabilization.
• Production & Packing — Available in tray packing and listed as mass production status for volume designs.

Typical Applications

• General-purpose power modules — Provides bulk capacitance and energy storage where 250 V-rated support and 330 µF value are required.
• Compact power assemblies — Low-profile φ30×20 mm form factor fits space-constrained boards and enclosures.
• High-temperature environments — Designed for use in systems operating up to 105 °C with a 3000‑hour endurance rating.
• Production-volume builds — Tray packing and mass-production availability support repeatable procurement and assembly.

Unique Advantages

• High-voltage capacitance in a compact package: 330 µF at 250 V delivers substantial energy storage while maintaining a φ30×20 mm low-profile footprint.
• Designed for elevated temperatures: 3000 hours rated life at 105 °C provides predictable longevity for high-ambient applications.
• Frequency-aware ripple capability: Clear ripple current specs (1.08 A @ 120 Hz, 1.62 A @ 50 kHz) and series frequency coefficients allow designers to size decoupling and filtering with confidence across application frequencies.
• Robust mounting option: Snap-in radial can simplifies mechanical assembly for production environments requiring secure PCB attachment.
• Production-ready packaging: Tray packing and mass-production status facilitate procurement and high-volume assembly planning.
