LGW2E331MELZ30

The LGW2E331MELZ30 is a Nichicon LGW series aluminum electrolytic capacitor in a snap‑in radial can package. It delivers 330 µF capacitance at a 250 V rating with polarized terminals and is specified for general‑purpose power applications.

Designed for high ripple current environments and continuous operation up to 105°C, this part targets board‑level power electronics where robust filtering and energy storage are required while maintaining RoHS compliance.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance, suitable for mid‑voltage power circuits.
• High Ripple Current — Rated ripple current capability includes 1.8 A at 120 Hz and 2.7 A at 50 kHz, supporting applications with significant AC components on DC rails.
• High Temperature Endurance — Rated for operation from −40°C to +105°C and specified for 3000 hours at 105°C under rated ripple conditions.
• Package and Mounting — Radial, snap‑in can package for secure PCB mounting and through‑hole assembly; physical size approximately L: 3 cm × D: 2.2 cm with a seated height up to 1.181 inch.
• Polarized Design — Polar capacitor construction for DC power applications requiring electrolytic bulk capacitance.
• Regulatory Compliance — Compliant to the RoHS Directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Power Electronics — Bulk energy storage and smoothing in general‑purpose power circuits that require a 330 µF, 250 V polarized capacitor with high ripple tolerance.
• Industrial Power Supplies — Board‑level filtering and decoupling in industrial power supplies where elevated ambient temperature and ripple currents are present.
• Electronic Assemblies — Through‑hole, snap‑in mounting for mechanically secure installation in assemblies that benefit from robust radial can capacitors.

Unique Advantages

• High ripple tolerance: Specified ripple current values at both low and high frequencies support demanding AC‑on‑DC conditions without compromising performance.
• Extended high‑temperature life: 3000 hours endurance at 105°C under rated ripple provides predictable long‑term behavior in hot environments.
• Compact radial footprint: 3.0 cm × 2.2 cm can size with snap‑in terminals balances board space and capacitance for mid‑voltage designs.
• Polarized aluminum electrolytic construction: Offers high capacitance per volume for bulk storage where polarity is controlled in the circuit.
• RoHS compliant: Meets current RoHS requirements, simplifying environmental and compliance considerations for product assemblies.
