LGR2E561MELA50

The LGR2E561MELA50 from Nichicon is a snap-in terminal aluminum electrolytic capacitor from the LGR long-life series. It provides 560 µF nominal capacitance at a 250 V rating and is specified for operation to 105°C with long-life assurance.

Designed for general-purpose applications, this radial can snap-in capacitor combines high-voltage capability and extended endurance to support power electronics designs that require sustained performance under elevated temperature and ripple conditions.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• High-temperature, Long-life Design — Rated for operation from −40°C to +105°C and specified for 10,000 hours endurance at 105°C under D.C. bias plus rated ripple current.
• Snap-in Radial Package — Snap-in terminal, radial can construction for secure board mounting; size approximately L: 5 × D: 2.5 cm with a seated height maximum of 1.969 inch.
• Ripple Current Performance — Rated ripple current of 1.5 A at 120 Hz (low frequency) and 2.25 A at 50 kHz (high frequency). Frequency coefficient of rated ripple current for the 200/250 V group is 1.00 at 120 Hz and 1.50 at 50 kHz.
• Polarized with Controlled Leakage — Polarized construction; leakage current is specified as I ≤ 3√(C·V) µA after 5 minutes’ application of rated voltage at 20°C (C = µF, V = V).
• RoHS Compliant — Manufactured in compliance with the RoHS directive.

Typical Applications

• General Purpose Power Electronics — Suitable where a 250 V, 560 µF snap-in electrolytic is required for bulk energy storage or smoothing in general-purpose circuits.
• High-Temperature Environments — Appropriate for applications requiring continuous operation up to 105°C with extended life expectations.
• Board-Mounted High-Voltage Filters — Snap-in radial form factor facilitates secure mounting in filter and power supply assemblies operating at higher voltages.

Unique Advantages

• Extended Endurance: 10,000-hour rating at 105°C ensures prolonged service life under D.C. bias plus rated ripple, reducing maintenance and replacement frequency.
• High Voltage Capability: 250 V rating addresses higher-voltage supply rails while maintaining substantial capacitance for bulk decoupling.
• Solid Ripple Handling: Specified ripple current at both low and high frequencies plus published frequency coefficients allow designers to predict performance across operating spectra.
• Reliable Leakage Performance: Leakage current bounded by the I ≤ 3√(C·V) µA formula provides a predictable baseline for leakage budgeting in power designs.
• RoHS Compliance: Meets environmental directive requirements for lead-free assemblies and regulatory compliance.
• Secure Snap-in Mounting: Radial, snap-in can package offers mechanical robustness for chassis and PCB mounted power modules.
