LAS2W820MELZ30

The LAS2W820MELZ30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAS series designed for general-purpose power applications. It combines a high 450 V rating with an 82 µF capacitance in a smaller snap-in can package engineered for elevated temperature and ripple endurance.

This capacitor is targeted at equipment operating in voltage-fluctuating environments and industrial power systems where sustained ripple performance and enhanced safety under abnormal voltage conditions are required.

Key Features

• Electrical Rating — 82 µF capacitance at a 450 V rated voltage with polarization and a capacitance tolerance of ±20% (at 120 Hz, 20°C).
• High-temperature Endurance — Rated for operation from −25°C to +105°C and specified to withstand 2000 hours at 105°C with application of rated ripple current.
• Ripple Current Capability — Rated ripple current of 650 mA at 120 Hz and 747.5 mA at 10 kHz; frequency coefficient of rated ripple current increases with frequency (for example: 1.00 at 120 Hz, 1.15 at 10 kHz).
• Compact Snap-in Package — Radial, can-type snap-in mounting simplifies PCB assembly while offering smaller case sizes compared to the LAQ series.
• Improved Safety for Abnormal Voltage — Designed with enhanced safety features and a pressure-relief vent; series safety performance includes specific abnormal-voltage test conditions for the 450 V class (C < 100 μF limited DC current 2 A at test voltages 550 VDC and 675 VDC).
• Lifecycle and Shelf Stability — Endurance and shelf-life specifications detailed for maintaining capacitance, tan δ and leakage current after rated stress and storage conditions.
• RoHS Compliant — Meets RoHS directive (2011/65/EU,(EU)2015/863) requirements.
• Physical Size — Body dimensions approximately L: 3.0 cm × D: 2.2 cm with a maximum seated height of 1.181 inch for PCB planning.

Typical Applications

• Industrial Power Supplies — Provides bulk energy storage and ripple smoothing in high-voltage power supplies used in industrial controllers and equipment.
• Power Conditioning and UPS — Suited for smoothing and energy buffering where sustained ripple current and 105°C operation improve reliability under heavy load.
• Equipment in Voltage‑Fluctuating Areas — Built for systems exposed to abnormal or fluctuating voltages, offering improved safety features and surge test capability.
• High-Voltage DC Link and Filter Circuits — Used in DC link and filtering roles where 450 V rating and elevated ripple endurance are required.

Unique Advantages

• High-temperature reliability: Specified 2000 hours at 105°C under rated ripple current, supporting demanding thermal environments.
• High-voltage capability: 450 V rating enables use in high-voltage power designs without series stacking.
• Compact, robust mounting: Snap-in radial can reduces board footprint while simplifying mechanical retention and assembly.
• Enhanced abnormal-voltage safety: Pressure-relief design and series-level abnormal-voltage tests help mitigate hazardous failure modes.
• Frequency-aware ripple performance: Ripple current rating and frequency coefficients allow designers to size capacitors accurately across 120 Hz to 10 kHz operating ranges.
• Regulatory compliance: RoHS compliance supports use in markets requiring restricted substance adherence.
