LAS2W221MELB35

The LAS2W221MELB35 is a Nichicon LAS series aluminum electrolytic capacitor in a snap-in terminal, smaller-sized can package. It provides 220 µF capacitance at a 450 V rating and is designed for general-purpose use in equipment operating in fluctuating voltage environments.

Built for sustained high-temperature operation, this part withstands 2000 hours of rated ripple current at 105°C and delivers elevated ripple-current capability compared with earlier LAQ series designs, while incorporating improved safety features against abnormally excessive voltage.

Key Features

• 220 µF capacitance, 450 V rating — Suitable for high-voltage DC applications that require bulk energy storage at 450 V.
• Snap-in terminal, radial can package — Robust snap-in mounting for secure board retention in power assemblies.
• High-temperature endurance — Rated for operation from −25 °C to +105 °C and specified to withstand 2000 hours of application of rated ripple current at 105 °C.
• Ripple-current capability — Rated ripple current of 1.3 A at 120 Hz and 1.495 A at 10 kHz; frequency coefficients apply (120 Hz = 1.00, 10 kHz or more = 1.15).
• Capacitance tolerance and stability — ±20% tolerance at 120 Hz, 20 °C; endurance limits specify capacitance change within ±20% after the endurance test.
• Enhanced safety design — Pressure relief vent behavior specified to operate without flames or dangerous dispersion under test conditions for abnormal voltages.
• Compact footprint — Smaller case sizes compared with LAQ series while offering higher ripple current handling; nominal size L: 3.5 × D: 3 cm.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power-supply filtering and energy storage — Provides bulk capacitance and ripple-current handling in supplies exposed to voltage fluctuation.
• Industrial equipment operating under fluctuating voltages — Engineered for environments with variable input voltages where long high-temperature endurance is required.
• General-purpose high-voltage assemblies — Applicable where 450 V rating and compact snap-in mounting are needed for reliable DC smoothing.

Unique Advantages

• High-voltage capability: 450 V rating supports demanding DC voltage applications without derating the capacitor’s core function.
• Extended high-temperature endurance: Qualified for 2000 hours at 105 °C under rated ripple current, providing predictable life performance in hot environments.
• Elevated ripple-current performance: Higher ripple current than comparable LAQ series parts and explicit ripple-current ratings at 120 Hz and 10 kHz for design confidence.
• Improved abnormal-voltage safety: Pressure relief venting is specified to avoid dangerous conditions under abnormal voltage tests.
• Compact, board-friendly package: Snap-in radial can reduces assembly complexity while maintaining high-voltage and high-temperature capability.
• Regulatory compliance: RoHS conformity supports deployment in markets requiring restricted-substance compliance.
