LAK2D561MELZ45

The LAK2D561MELZ45 is an aluminum electrolytic capacitor in a snap‑in terminal can designed for general‑purpose power applications. It delivers 560 µF at a 200 V rating with polarized construction and is part of Nichicon's LAK series optimized for equipment exposed to fluctuating supply voltages.

Engineered for high‑temperature operation, this capacitor supports an operating range from −25°C to 105°C and is specified to withstand 2000 hours of rated ripple current at 105°C, providing measurable endurance where sustained ripple and elevated ambient temperatures are present.

Key Features

• Capacitance and Voltage — 560 µF rated capacitance with a 200 V nominal voltage and ±20% tolerance for general power‑supply and energy‑storage use.
• High‑Temperature Endurance — Specified to endure 2000 hours at 105°C with DC bias plus rated ripple current; capacitance change and leakage current limits are defined by the LAK series endurance criteria.
• Rated Ripple Current — 1.5 A at 120 Hz and 1.8 A at 10 kHz, enabling continuous ripple handling in designs where AC components are present on the DC line.
• Safety‑Oriented Design — Improved safety features for abnormally excessive voltage and a pressure relief vent designed to operate without dangerous flames or dispersion under the series' safety performance tests.
• Snap‑in Radial Package — Radial, can‑type snap‑in mounting for secure board attachment; physical size L: 4.5 × D: 2.2 cm supports compact PCB layouts.
• Environmental Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Voltage‑fluctuation equipment — Suited to equipment and systems operating in environments with fluctuating supply voltages where abnormal voltage tolerance and safety venting are important.
• General‑purpose power systems — Applicable for power modules and systems requiring bulk capacitance and sustained ripple handling at elevated temperatures.
• High‑temperature installations — Useful in applications that require reliable capacitor performance up to 105°C and defined long‑term endurance under rated ripple conditions.

Unique Advantages

• Proven endurance at elevated temperature — Rated to withstand 2000 hours of DC bias plus rated ripple current at 105°C, offering predictable long‑term performance under thermal stress.
• Designed for ripple‑intensive environments — Specified ripple current values at 120 Hz and 10 kHz provide designers with clear limits for AC stress handling.
• Safety performance testing — Series safety tests define pressure relief behavior and limited DC current conditions; for 200 V units with capacitance ≥470 µF, the safety test limits include 7 A under test voltages of 300 VDC and 375 VDC.
• Compact, robust mounting — Snap‑in radial can package (L: 4.5 × D: 2.2 cm) simplifies board assembly while providing a stable mechanical connection.
• Regulatory compliance — RoHS compliance supports use in designs with restricted hazardous substance requirements.
