LAK2D561MELC25

The LAK2D561MELC25 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor from the LAK series, rated 200V with 560µF capacitance and ±20% tolerance. Designed for general‑purpose power applications, it delivers high working voltage, elevated operating temperature capability, and snap‑in mechanical retention for secure installation.

Key value propositions include endurance under elevated temperature and ripple conditions, built‑in safety measures for abnormal overvoltage, and RoHS compliance for regulatory compatibility.

Key Features

• Electrical Performance — 560 µF capacitance at 200 V rated voltage with ±20% tolerance; polarized design tailored for DC power circuits.
• Ripple Handling — Rated ripple current of 1.55 A at 120 Hz and 1.86 A at 10 kHz, enabling effective smoothing under typical and higher‑frequency ripple conditions.
• High‑Temperature Endurance — Operates across −25°C to +105°C and withstands 2000 hours of rated ripple current at 105°C, with defined endurance limits for capacitance, tan δ and leakage after stress.
• Reliability Parameters — Leakage current specified as I ≤ 3√(C·V) µA after 5 minutes (20°C); tan δ ≤ 0.20 (120 Hz, 20°C); endurance and shelf‑life recovery criteria defined in the LAK series datasheet.
• Safety Features — Improved safety design for abnormally excessive voltage and a pressure relief vent that operates without producing flames or hazardous dispersion under test conditions.
• Package & Mounting — Radial, can – snap‑in package for firm PCB retention; compact dimensions L: 2.5 × D: 3.5 cm with printed white marking on black sleeve.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — General‑purpose smoothing and energy storage for DC power supplies that require 200 V working voltage and robust ripple handling.
• Equipment Operating in Voltage‑Fluctuating Areas — The LAK series is described as ideally suited for equipment subject to voltage fluctuation, providing stability under variable input conditions.
• High‑Temperature Environments — Circuits that encounter elevated ambient temperatures up to 105°C benefit from the component’s 2000‑hour endurance at rated conditions.
• Chassis‑Mounted Power Modules — Snap‑in terminal package provides secure mechanical mounting for power assemblies and modules.

Unique Advantages

• High Working Voltage (200 V): Supports designs that require elevated DC voltage handling without changing capacitor family.
• Long Endurance at Elevated Temperature: Rated to withstand 2000 hours of rated ripple current at 105°C, reducing maintenance and replacement frequency in demanding environments.
• Measured Ripple Specifications: Explicit ripple ratings at 120 Hz and 10 kHz give designers clear targets for thermal and lifetime calculations.
• Safety‑Focused Design: Enhanced safety features and a pressure relief vent reduce the risk of hazardous failures under abnormal voltage stress.
• Snap‑in Mechanical Retention: Radial can snap‑in package ensures reliable board attachment for power assemblies and simplifies assembly handling.
• RoHS Compliance: Meets modern regulatory requirements for lead‑restricted applications.
