LAS2G271MELA40

The LAS2G271MELA40 is a snap-in terminal aluminum electrolytic capacitor in Nichicon's LAS series, specified for general-purpose applications requiring high-voltage smoothing and ripple handling. It is a polarized, radial can snap-in device with a rated capacitance of 270 µF at 400 V and designed for continuous operation across a −25°C to +105°C temperature range.

Engineered for extended endurance under elevated temperature and ripple stress, this part is rated for 2000 hours at 105°C and includes safety features for abnormal over-voltage conditions. The component is supplied in tray packing and is intended for mass-production use.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 400 V rated working voltage for high-voltage DC filtering and energy storage in general-purpose circuits.
• Tolerance & Polarization — Capacitance tolerance ±20% at 120 Hz, 20°C; polarized configuration for correct orientation in DC circuits.
• High-Temperature Endurance — Endurance rating of 2000 hours at 105°C when DC bias plus rated ripple current is applied, with limits for capacitance change, tan δ, and leakage current defined.
• Ripple Current Performance — Rated ripple current of 1.3 A at 120 Hz and 1.495 A at 10 kHz; frequency coefficient table applies for other frequencies.
• Package & Mounting — Radial, can-type snap-in package (snap-in terminal) for robust PCB mounting; listed dimensions include φ30×40L and size dimension L: 4 cm × D: 2.5 cm.
• Safety & Reliability — Designed with improved safety features for abnormal excessive voltage; pressure relief vent operates under abnormal conditions to prevent dangerous outcomes.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863) as stated in the datasheet.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and ripple smoothing in DC systems where a 400 V rating and 270 µF are required.
• Equipment in fluctuating-voltage environments — Suited for use in equipment exposed to variable supply voltages thanks to improved safety measures against abnormal over-voltage events.
• High-temperature installations — Applicable where operation up to 105°C and long endurance under rated ripple current (2000 hours) are needed.

Unique Advantages

• 400 V rating for high-voltage circuits: Enables use in higher-voltage DC filtering and energy storage applications without stepping down system voltage.
• Extended endurance at elevated temperature: 2000-hour rating at 105°C under DC bias plus rated ripple current supports long-term reliability in hot operating environments.
• Defined ripple current capability: Published ripple current values at 120 Hz and 10 kHz allow designers to size capacitors against expected ripple loads with frequency coefficients available for other frequencies.
• Snap-in radial can packaging: Provides a mechanically secure, PCB-mounted solution suitable for high-current and high-voltage assemblies.
• Built-in safety venting: Pressure relief vent operation mitigates dangerous failures under abnormal over-voltage, improving system safety.
• RoHS compliant and production-ready: Meets environmental directives and is supplied in tray packing for mass-production assembly workflows.
