LAK2D681MELC30

The LAK2D681MELC30 from Nichicon is a snap-in terminal aluminum electrolytic capacitor rated at 680 µF and 200 V. Engineered for general-purpose power applications, it combines a snap-in radial can package (φ35 × 30 mm) with a 105°C permissible operating range and enhanced safety characteristics for abnormal voltages.

Key value propositions include robust ripple-current handling, extended endurance at elevated temperature, and specifications that support use in equipment exposed to voltage fluctuations.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• High-Temperature Endurance — Rated for continuous operation up to 105°C with an endurance life of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Snap-in Radial Package — Snap-in terminal type in a radial can (φ35 × 30 mm) for secure board mounting and easy assembly.
• Ripple Current Capacity — Rated ripple current of 1.7 A at 120 Hz (105°C) and 2.04 A at 10 kHz, supporting applications with substantial ripple demands.
• Leakage and Loss Characteristics — Specified leakage current of 1.10 mA and tangent of loss angle (tan δ) up to 0.20 max. at 120 Hz, 20°C.
• Safety and Abnormal Voltage Design — Designed with improved safety features and pressure-relief vent behavior to limit dangerous conditions under abnormal voltage stress.
• Regulatory Compliance & Packaging — RoHS compliant and supplied in tray packing for production handling.

Typical Applications

• Power supplies — Bulk filtering and smoothing where a 200 V rated capacitor with substantial ripple-handling is required.
• Industrial equipment — Systems operating in environments with voltage fluctuation benefit from the part’s endurance at 105°C and safety features for abnormal voltage.
• High-ripple DC bus circuits — Applications that require sustained ripple current capability at 120 Hz and higher frequencies.
• General-purpose electronic assemblies — Use where a robust, polarized aluminum electrolytic capacitor in a snap-in package is suitable.

Unique Advantages

• Endurance at Elevated Temperature: 2000 hours at 105°C when subjected to rated ripple current provides predictable life performance in high-temperature installations.
• Strong Ripple Performance: 1.7 A (120 Hz) and 2.04 A (10 kHz) ripple ratings support designs with heavy AC components on DC rails.
• Designed for Voltage Fluctuation: Improved safety features and pressure-relief behavior reduce risk in equipment exposed to abnormal voltage conditions.
• Measurable Electrical Stability: Tightly specified tan δ (≤0.20) and defined leakage current enable easier thermal and loss budgeting in power designs.
• RoHS Compliance and Production Packaging: Environmentally compliant material set and tray packing streamline manufacturing and procurement.
