LAK2D271MELC20

The LAK2D271MELC20 is an aluminum electrolytic capacitor in a snap‑in radial can designed for general‑purpose power applications. It is a 270 µF, 200 V polarized capacitor from Nichicon’s LAK series, built for operation across −25 °C to 105 °C and engineered for environments with fluctuating supply voltages.

Key value propositions include a 105 °C permissible abnormal voltage design, a 2000‑hour endurance at 105 °C with rated ripple current, and safety measures to mitigate the effects of excessive voltage.

Key Features

• Capacitance and Voltage: 270 µF rated capacitance at 200 V, with ±20% tolerance, suitable for mid‑range DC bus and smoothing applications.
• High Temperature Endurance: Specified to withstand 2000 hours when subjected to D.C. bias plus rated ripple current at 105 °C, with restoration to 20 °C meeting endurance criteria.
• Ripple Current Capability: Rated ripple current of 1.1 A at 120 Hz and 1.32 A at 10 kHz, allowing effective ripple handling in power circuits where these frequencies are present.
• Safety Features: Designed with improved safety for abnormally excessive voltage; pressure relief vent operates under abnormal conditions without creating flames or dispersion of parts.
• Operating Temperature Range: −25 °C to 105 °C, supporting elevated‑temperature applications and thermal robustness within the specified range.
• Package and Mounting: Snap‑in radial can package (L: 20 mm × D: 35 mm; seated height max 20 mm) for secure PCB or chassis mounting in compact assemblies.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863), meeting common restriction of hazardous substances requirements.

Typical Applications

• Industrial power equipment: Bulk smoothing and energy storage where a 200 V, 270 µF capacitor with snap‑in mounting is required and supply voltages may fluctuate.
• Power supplies and converters: DC bus decoupling and ripple attenuation using the specified ripple current ratings at 120 Hz and 10 kHz.
• Uninterruptible power systems and backup modules: Energy buffering in systems that demand endurance at elevated temperatures (2000 hours at 105 °C under rated ripple).
• General‑purpose commercial electronics: Applications that require a polarized aluminum electrolytic capacitor with robust safety features and RoHS compliance.

Unique Advantages

• Proven high‑temperature endurance: 2000 hours endurance at 105 °C under rated ripple current reduces the need for frequent replacement in hot operating environments.
• Measured ripple performance: Explicit ripple ratings (1.1 A at 120 Hz, 1.32 A at 10 kHz) allow designers to match capacitor selection to actual circuit ripple conditions.
• Enhanced safety under abnormal voltage: Pressure relief vent and permissible abnormal voltage design mitigate hazardous failure modes during overvoltage events.
• Compact, secure mounting: Snap‑in radial can provides a reliable mechanical connection for power boards and chassis assemblies.
• Regulatory compliance: RoHS compliance supports use in applications requiring restricted‑substance conformity.
