LGW2E561MELZ45

The LGW2E561MELZ45 from Nichicon is a snap-in terminal aluminum electrolytic capacitor designed for high ripple current operation at elevated temperatures. It provides 560 µF capacitance at a 250 V rating in a radial, can-style snap-in package intended for general-purpose applications.

Key value propositions include high ripple-current capability with verified endurance at 105°C and compliance with RoHS (2011/65/EU, (EU)2015/863), supporting reliable operation in demanding power environments.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a 250 V rated voltage; capacitance tolerance ±20% at 120 Hz, 20°C.
• High Ripple Current — Rated ripple current specifications include 2.25 A at 120 Hz and 3.375 A at 50 kHz, with frequency coefficients available for scaling across common frequencies.
• 105°C Endurance — Designed to withstand 3,000 hours of rated ripple-current application at 105°C when operated within specified limits.
• Wide Operating Temperature — Specified operating range from −40°C to 105°C for the 200–250 V class.
• Leakage and Dissipation — Leakage current meets I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ maximum for the 200–400 V range is 0.15 (measured at 120 Hz, 20°C).
• Package & Mounting — Radial, snap-in can package (L: 4.5 × D: 2.2 cm) for secure board mounting and straightforward assembly.
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power supplies — Bulk capacitance and high ripple capability support smoothing and DC-bias applications in power conversion circuits.
• Industrial equipment — Rated for continuous operation at elevated temperatures, suitable for high-stress power environments in industrial systems.
• High-frequency power circuits — Frequency-scaled ripple-current performance supports applications operating across a wide frequency range up to and beyond 50 kHz.

Unique Advantages

• Proven high-temperature endurance — Withstanding 3,000 hours of rated ripple current at 105°C reduces the need for frequent replacement in hot operating conditions.
• Clear performance scaling — Frequency coefficients for rated ripple current allow engineers to calculate ripple capability across 50 Hz to 50 kHz+ operating points.
• Robust leakage and dissipation characteristics — Specified leakage-current formula and tan δ limits provide predictable behavior for design margining and reliability.
• Snap-in mounting for reliable assembly — Radial snap-in can package offers a secure mounting option for high-current power boards.
• Regulatory compliance — RoHS compliance simplifies integration into products subject to restricted substance regulations.
