LGZ2W331MELC50

The LGZ2W331MELC50 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGZ long‑life series. It delivers 330 µF capacitance at a 450 V rating in a radial, snap‑in can optimized for through‑hole assemblies.

Designed for general‑purpose use where extended operating life and elevated temperature endurance are required, this capacitor supports equipment longevity with a rated lifetime of 20,000 hours at 105°C and RoHS compliance.

Key Features

• Electrical — 330 µF nominal capacitance at 450 V DC with ±20% tolerance (measured at 120 Hz, 20°C); polarized design for DC applications.
• Thermal & Endurance — Operating range –25°C to +105°C and endurance rated for 20,000 hours at 105°C under DC bias plus rated ripple current; designed to contribute to longer equipment life.
• Ripple Performance — Rated ripple current 1.38 A at 120 Hz (105°C) and 1.973 A at 50 kHz, with frequency coefficients provided in the series datasheet for higher‑frequency operation.
• Reliability Characteristics — Leakage current specified as I ≤ 3√(C·V) μA (after 5 minutes at 20°C); tan δ ≤ 0.20 (120 Hz, 20°C); impedance ratio Z(–25°C)/Z(+20°C) = 8 for 450 V types.
• Package & Mounting — Radial, snap‑in can package (φ35 × 50 mm); snap‑in terminals for secure PCB retention in through‑hole assemblies; marking printed in white on a black sleeve.
• Shelf Life & Stability — Shelf life treatment specified (105°C for 1000 hours followed by voltage treatment) with defined recovery limits: capacitance change within ±15%, tan δ ≤ 150% of initial spec, leakage ≤ initial spec.
• Regulatory — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Equipment — Use where a robust, long‑life polarized capacitor is required to support DC filtering and energy storage in general electronics assemblies.
• High‑Temperature Environments — Suitable for designs that operate continuously at elevated temperatures up to 105°C, backed by 20,000‑hour endurance data.
• Through‑Hole / Snap‑In PCB Assemblies — Snap‑in terminal and radial can package provide secure mechanical retention for power assemblies and large‑form factors.

Unique Advantages

• Extended operational life: 20,000 hours at 105°C provides predictable long‑term performance to support longer equipment service life.
• High voltage capability: 450 V rating enables use in higher‑voltage DC applications while preserving capacitance and loss specifications.
• Documented ripple handling: Rated ripple currents specified at both low and high frequencies (1.38 A at 120 Hz; 1.973 A at 50 kHz) with frequency coefficients available for design calculations.
• Thermal stability: –25°C to +105°C operating range and specified impedance ratio at low temperature allow predictable behavior across a wide thermal envelope.
• Manufacturing‑friendly mounting: Snap‑in radial can simplifies through‑hole assembly and mechanical retention on PCBs.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements.
