LAK2D561MELA40

The LAK2D561MELA40 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications requiring a 200 V rated voltage and 560 µF capacitance. It is part of Nichicon’s LAK series, engineered for extended ripple endurance and safety in environments with fluctuating voltages.

This radial, can‑style, snap‑in capacitor offers a compact 25 mm diameter × 40 mm length package and is specified for continuous operation from −25°C to +105°C, with 2000 hours endurance at 105°C under rated conditions.

Key Features

• Electrical Performance — 560 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C) and a rated voltage of 200 V, suited for bulk energy storage and smoothing on 200 V rails.
• Ripple Handling — Rated ripple current of 1.5 A at 120 Hz and 1.8 A at 10 kHz, enabling handling of low‑ and high‑frequency ripple in power supply and converter applications.
• Loss & Leakage — Tangent of loss angle (tan δ) maximum 0.20 at 120 Hz, 20°C, and specified leakage current of 1.00 mA, supporting predictable dissipation and standby characteristics.
• Temperature & Endurance — Category temperature range −25°C to +105°C with endurance validated to 2000 hours at 105°C under DC bias plus rated ripple current, ensuring long‑term stability in high‑temperature environments.
• Safety Features — Designed with improved safety measures for abnormal overvoltage conditions; includes a pressure relief vent that operates without dangerous flaming or dispersion of parts under test conditions.
• Package & Mounting — Snap‑in terminal, radial can configuration (φ25 mm × 40 mm), for secure PCB mounting in high‑current power sections.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy storage on 200 V rails where elevated temperature endurance and significant ripple handling are required.
• DC Link / Converter Filtering — Support for DC bus decoupling and ripple attenuation in AC/DC and DC/DC converters operating near 200 V.
• General Purpose Electronic Equipment — Reliable bulk capacitance for control panels, instrumentation, and equipment subject to voltage fluctuations and elevated ambient temperatures.

Unique Advantages

• 200 V Rated Voltage: Enables direct use on higher‑voltage rails without additional series components.
• High Temperature Endurance: 2000 hours at 105°C under rated ripple current provides predictable lifetime in hot operating environments.
• Dual‑Frequency Ripple Capability: Specified ripple current at both 120 Hz and 10 kHz supports designs that encounter a range of ripple frequencies.
• Safety‑Oriented Design: Pressure relief vent and improved overvoltage safety features reduce risk during abnormal voltage events.
• Compact Snap‑in Form Factor: Radial snap‑in mounting offers robust mechanical retention and straightforward PCB layout in power sections.
• Regulatory Compliance: RoHS conformity simplifies integration into assemblies targeting regulated markets.
