LAS2G271MELB35

The LAS2G271MELB35 is a Nichicon LAS series aluminum electrolytic capacitor in a snap-in, radial can package (φ30 × 35 mm). It delivers 270 µF capacitance at a 400 V rating and is polarized for general-purpose high-voltage use.

Engineered for equipment operating in areas with voltage fluctuation, this part combines 105°C endurance, elevated ripple-current capability, and enhanced safety features to support robust power-conditioning and bulk-decoupling applications.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance with a 400 V DC rating and ±20% tolerance (at 120 Hz, 20°C), suitable for high-voltage smoothing and energy storage.
• High-temperature Endurance — Designed to withstand 2000 hours of DC bias plus rated ripple current at 105°C while meeting endurance specifications for capacitance, tan δ, and leakage current.
• Snap-in Radial Can Package — Snap-in terminal design in a compact φ30 × 35 mm can for secure mounting and space-efficient board layouts.
• Ripple Current Capability — Rated ripple current of 1.3 A at 120 Hz and 1.495 A at 10 kHz; frequency coefficient data indicate increased allowable ripple at higher frequencies (coefficient up to 1.15 at 10 kHz or more).
• Safety Features — Pressure relief vent designed to operate without flames, ignition, or case dispersion under abnormal voltage conditions; validated safety performance includes limited DC current testing for overvoltage scenarios (for 400 V, C ≥ 220 µF: 7 A limited DC current test at 500 VDC and 600 VDC).
• Operating Range — Rated for use from −25°C to +105°C, supporting elevated-temperature applications where long-term stability is required.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose high-voltage power supplies — Bulk decoupling and smoothing at 400 V DC for industrial and commercial power systems.
• Equipment in voltage-fluctuating environments — Designed with improved safety features and endurance to handle applications exposed to transient or unstable supply conditions.
• Power conditioning and energy storage — Provides bulk capacitance and ripple handling in high-voltage assemblies requiring a compact snap-in solution.
• Panel- and chassis-mounted power modules — Snap-in mounting enables reliable mechanical retention for larger-can electrolytic capacitors in compact layouts.

Unique Advantages

• Proven 105°C endurance: 2000-hour rated-life under rated ripple current ensures predictable aging and performance in elevated-temperature installations.
• Elevated ripple performance: Specified ripple current values at 120 Hz and 10 kHz plus frequency coefficients enable designers to size capacitors confidently across switching and line frequencies.
• Compact, serviceable snap-in form: Smaller case size than comparable LAQ series parts offers space savings while maintaining high-voltage capability.
• Enhanced safety under overvoltage: Pressure-relief venting and validated limited DC current testing help mitigate abnormal-voltage risks without producing dangerous failure modes.
• RoHS compliance: Meets applicable RoHS directives for regulated substance restrictions.
• Clear, verifiable specifications: Leakage current, tan δ, impedance ratios, and shelf-life/endurance limits are defined in the LAS series datasheet for predictable integration and qualification.
