LAS2G331MELB35

The LAS2G331MELB35 is a 330 µF, 400 V aluminum electrolytic capacitor in a snap‑in radial can designed for general-purpose power applications. It is a snap‑in terminal type built for elevated operating conditions, rated for continuous use up to 105°C and designed to withstand prolonged ripple stress.

Key differentiators include a reduced case size compared with earlier LAQ series parts, improved safety features for abnormally excessive voltage, and RoHS compliance—making it suitable for equipment operating in voltage-fluctuating environments that require reliable high-temperature ripple endurance.

Key Features

• Rated Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 400 V and capacitance tolerance of ±20%.
• High‑Temperature Endurance — Specified for operation from −25°C to +105°C with endurance demonstrated for 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current of 1.44 A at 120 Hz and 1.656 A at 10 kHz, with frequency coefficients provided for other frequencies.
• Snap‑In Radial Package — Compact snap‑in can (φ30 × 35 mm) for secure PCB mounting and reduced board footprint compared with predecessor series.
• Safety Design — Improved safety features for abnormally excessive voltage; pressure relief vent is designed to operate without producing flames or dangerous dispersion under the specified safety tests.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• General‑purpose power systems — Performs as a bulk storage and smoothing capacitor where a robust 400 V, 330 µF part is required.
• Equipment in voltage‑fluctuating areas — Designed and specified for use in environments where input voltage may vary, thanks to its improved safety features and ripple endurance.
• High‑temperature installations — Suitable for applications that require continuous operation up to 105°C and verified endurance under rated ripple current.

Unique Advantages

• Proven high‑temperature ripple endurance — Endurance validated for 2000 hours at 105°C under rated ripple conditions, providing predictable performance in hot operating environments.
• Compact snap‑in footprint — Smaller case size versus the LAQ series enables board space savings while retaining high capacitance and voltage rating.
• Measured ripple performance — Specified ripple current values at 120 Hz and 10 kHz (1.44 A and 1.656 A respectively) with frequency coefficients for other operating frequencies.
• Enhanced safety behavior — Pressure relief vent and controlled test ratings reduce the risk of hazardous failure modes under abnormal voltage stress.
• Regulatory compliance — RoHS compliance supports use in designs requiring restricted substance conformity.
