LAK2D271MELC20ZB

The LAK2D271MELC20ZB is a snap‑in terminal type aluminum electrolytic capacitor from Nichicon's LAK series, rated 270 µF at 200 V. It is designed for general‑purpose power electronics where high ripple handling, high‑temperature endurance and robust safety performance are required.

Key value propositions include a 2000‑hour endurance at 105°C, snap‑in mounting for secure board installation, and built‑in safety measures for abnormal over‑voltage conditions—making it well suited for equipment operating in voltage‑fluctuating environments.

Key Features

• Capacitance & Voltage: 270 µF rated at 200 V for bulk energy storage and smoothing in power circuits.
• High‑temperature Endurance: Rated for 2000 hours at 105°C to maintain performance in elevated ambient temperatures.
• Ripple Current Capability: 1.10 A (120 Hz) and 1.32 A (10 kHz) ripple current ratings to support AC ripple in power supply applications.
• Low Loss (tan δ): Maximum tan δ of 0.20 (120 Hz, 20°C) for controlled dissipation factor.
• Leakage Current: Typical leakage current of 0.69 mA after standard voltage application, supporting predictable standby behaviour.
• Mechanical & Mounting: Snap‑in terminal, radial can package (φ35 × 20 mm), tray packing for mass production assembly.
• Wide Operating Temperature Range: −25°C to +105°C per datasheet specification.
• Safety Features: Designed with improved safety measures for abnormally excessive voltage and a pressure relief vent to mitigate dangerous failure modes.
• Compliance: RoHS compliant.

Typical Applications

• General Purpose Power Electronics: Bulk smoothing and energy storage in general‑purpose power supplies and power conditioning equipment.
• Equipment in Fluctuating Voltage Environments: Designed for systems exposed to variable line conditions where enhanced over‑voltage safety is beneficial.
• High‑Temperature Power Modules: Suitable for modules and enclosures that operate up to +105°C with long‑term endurance requirements.

Unique Advantages

• Long Endurance at Elevated Temperature: 2000 hours at 105°C provides predictable long‑term performance in high‑temperature applications.
• Robust Ripple Handling: Specified ripple current at both low and high frequencies (1.10 A at 120 Hz, 1.32 A at 10 kHz) supports a range of switching and line conditions.
• Snap‑In Mounting for Reliable Assembly: Snap‑in terminals and tray packing facilitate secure board installation and efficient mass production handling.
• Built‑In Safety Measures: Improved safety features for abnormally excessive voltage and a pressure relief vent reduce risk of hazardous failure modes.
• Stable Electrical Characteristics: ±20% capacitance tolerance and tan δ ≤ 0.20 ensure predictable behavior for circuit design and simulation.
• Regulatory Compliance: RoHS compliance supports environmental and regulatory requirements.
