LASW6820MELA25

The LASW6820MELA25 is an aluminum electrolytic, snap-in terminal capacitor from Nichicon’s LAS series. It provides 82 µF capacitance at a 420 V rating in a compact radial can (φ25 × 25L) designed for high-voltage, general-purpose applications.

Built for demanding environments, this part is specified for operation from −25 °C to 105 °C with 2000 hours endurance at 105 °C under rated ripple current. The design offers higher ripple current in a smaller case than the LAQ series and includes improved safety features for abnormally excessive voltage. The product is RoHS compliant.

Key Features

• Electrical rating — 82 µF capacitance at 420 V nominal with ±20% tolerance, suitable for high-voltage bulk capacitance needs.
• High-temperature endurance — Rated endurance of 2000 hours at 105 °C when D.C. bias plus rated ripple current is applied, with capacitance change within ±20% after the test.
• Ripple current capability — Rated ripple current of 640 mA at 120 Hz and 736 mA at 10 kHz; frequency coefficients apply (e.g., 1.00 at 120 Hz, 1.15 at 10 kHz for 400–450 V series).
• Compact snap-in package — Radial, can-type snap-in mounting in a φ25 × 25L package for secure chassis or board mounting.
• Safety performance — Pressure relief vent designed to operate without dangerous conditions under the defined safety tests for abnormal voltage; rated test conditions and limited DC current are defined by capacitance and voltage categories in the LAS series specification.
• Operating range & stability — Specified operating temperature range of −25 °C to +105 °C and impedance stability characteristics for low-temperature operation.
• Environmental compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic equipment — Bulk capacitance and energy storage in equipment where a 420 V, 82 µF capacitor is required and general-purpose qualification is appropriate.
• Equipment operating in fluctuating-voltage areas — Intended for use in devices exposed to variable supply conditions thanks to improved safety features for abnormally excessive voltage.
• High-temperature assemblies — Circuits requiring capacitors specified for continuous operation up to 105 °C with long-duration ripple stress (2000 hours at 105 °C).

Unique Advantages

• Compact high-voltage solution: 82 µF at 420 V in a φ25 × 25L snap-in can provides high-voltage capacitance in a smaller case footprint compared to LAQ.
• Designed for sustained ripple stress: Rated ripple current values (640 mA at 120 Hz, 736 mA at 10 kHz) and 2000-hour endurance at 105 °C support sustained operation under ripple conditions.
• Improved abnormal-voltage safety: Pressure relief vent and defined safety test conditions reduce the risk of hazardous failure modes under abnormally excessive voltage.
• Wide operating temperature range: −25 °C to +105 °C rating accommodates applications with elevated ambient temperatures.
• Regulatory compliance: RoHS compliance (2011/65/EU, (EU)2015/863) supports use in regulated markets and assemblies.
