LAS2W271MELC30ZB

The LAS2W271MELC30ZB is a snap-in terminal aluminum electrolytic capacitor designed for high-voltage, high-ripple applications. With a 270 µF capacitance at a 450 V rating and a wide operating temperature range of −25°C to +105°C, it targets general-purpose power applications and equipment operating in voltage-fluctuating environments.

Engineered for durability, this part delivers 2000 hours of endurance at 105°C under rated ripple current, combined with safety design measures for abnormal over-voltage conditions and RoHS compliance for environmental consistency.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High-temperature Endurance — Rated for 2000 hours of operation at 105°C with DC bias plus rated ripple current applied, meeting the listed endurance criteria after recovery to 20°C.
• Ripple Current Capability — Handles 1.300 A at 120 Hz (low frequency) and 1.495 A at 10 kHz (high frequency), with frequency coefficients provided for other operating frequencies.
• Low-loss Characteristics — Specified tangent of loss angle (tan δ) up to 0.20 at 20°C and 120 Hz, enabling predictable dissipation behavior.
• Leakage Current — Specified leakage current of 1040 µA after standard voltage application conditions.
• Snap-in Terminal Package — Radial can with snap-in terminals for secure panel or chassis mounting; supplied in tray packing for production handling.
• Safety Features — Pressure relief vent and improved safety performance designed to operate without flames, ignition, or case dispersion under the specified tests for abnormal voltage.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Compact Size — Cylinder size approximately φ35 × 30 mm for space-constrained power assemblies.

Typical Applications

• Power supply ripple suppression — Bulk capacitance and specified ripple-current ratings support smoothing and decoupling in high-voltage power supplies and converters.
• Equipment in fluctuating voltage environments — Designed for systems exposed to variable line conditions, with safety measures for abnormal voltages and long endurance at elevated temperature.
• Industrial power electronics — Suitable where high-voltage filtering and reliable long-term operation at up to 105°C are required.

Unique Advantages

• High-voltage capability: 450 V rating provides the margin needed for many high-voltage power circuits and applications subject to voltage swings.
• Long life at elevated temperature: 2000-hour endurance at 105°C under rated ripple current supports reliable operation in thermally demanding environments.
• Strong ripple-handling: High specified ripple currents at both low and high frequencies reduce stress on the capacitor and help stabilize output in power systems.
• Robust safety design: Pressure relief vent and abnormal-voltage safety measures minimize the risk of hazardous failure modes under test conditions.
• Installation-ready package: Snap-in radial can and tray packing facilitate efficient assembly and handling in production environments.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements.
