LAS2W271MELC30

The LAS2W271MELC30 is a Nichicon aluminum electrolytic capacitor in a snap-in, radial can package designed for general-purpose power applications. It provides 270 µF capacitance at a 450 V rating and is polarized for DC use.

Engineered for demanding thermal and electrical conditions, this smaller-sized LAS series part supports operation from -25 °C to +105 °C, a rated ripple current endurance profile, and safety features for abnormally excessive voltage environments.

Key Features

• Electrical Core — 270 µF capacitance with a 450 V rated voltage and ±20% tolerance, suited for high-voltage DC applications requiring substantial energy storage.
• High-Temperature Endurance — Rated for operation up to 105 °C with an endurance specification of 2000 hours at 105 °C under rated ripple and DC bias.
• Ripple Current Performance — Rated ripple current of 1.3 A at 120 Hz and 1.495 A at 10 kHz; frequency coefficients are provided for frequency-dependent ripple calculations.
• Safety and Overvoltage Handling — Designed with improved safety features for abnormally excessive voltage and a pressure relief vent that operates under abnormal conditions without dangerous flame or dispersion.
• Package and Mounting — Snap-in radial can package for secure board mounting and space-efficient installation; nominal size L: 3 × D: 3.5 cm.
• Regulatory Compliance — RoHS compliant in accordance with the stated directive.

Typical Applications

• General-purpose power equipment — Serves as bulk energy storage and smoothing in assemblies where a 270 µF, 450 V polarized capacitor is required.
• Equipment exposed to voltage fluctuations — Intended for systems in which higher-than-normal voltage excursions can occur, leveraging the LAS series’ permissible abnormal voltage and safety venting.
• Space-constrained power assemblies — Smaller case size relative to related series while providing higher ripple current makes it suitable for compact power supply and converter modules.

Unique Advantages

• High-voltage capability: 450 V rating supports high-voltage DC bus and filtering applications without stepping down voltage requirements.
• Designed for high-temperature reliability: 2000-hour endurance at 105 °C under rated conditions provides predictable life performance in thermally demanding installations.
• Robust ripple handling across frequency: Specified ripple current values and frequency coefficients allow designers to size capacitors accurately for both low- and high-frequency ripple environments.
• Enhanced safety under abnormal voltage: Pressure relief vent and improved safety features reduce risk during overvoltage events while avoiding flame or part dispersion.
• Compact snap-in form factor: Radial, snap-in can reduces assembly time and saves board space compared to larger electrolytic housings.
• RoHS compliance: Meets stated RoHS requirements for environmentally conscious designs.
