LASW6820MELZ30ZB

The LASW6820MELZ30ZB is an aluminum electrolytic, snap-in terminal capacitor rated 82 µF at 420 V. It is a compact, radial can snap-in design (φ22 × 30 L, L: 3 cm × D: 2.2 cm) engineered for high-voltage, general-purpose power applications.

Designed for use where line voltage can fluctuate, this part delivers extended high-temperature endurance and elevated ripple-current capability, offering stability for power supplies and industrial equipment operating up to 105°C.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with a 420 V rated voltage and ±20% tolerance, suitable for high-voltage bulk filtering and energy storage.
• High-Temperature Endurance — Withstands 2000 hours of rated ripple-current application at 105°C; after endurance testing, capacitance remains within ±20% and leakage current is within initial specified limits.
• Ripple Current Performance — Rated ripple current of 640 mA at 120 Hz and 736 mA at 10 kHz, with frequency coefficients available (e.g., 120 Hz = 1.00, 10 kHz = 1.15) to size for varying frequencies.
• Improved Safety for Abnormal Voltage — Designed with enhanced safety features for abnormally excessive voltage and a pressure relief vent that operates without dangerous conditions such as flames or dispersion of parts under test conditions.
• Package & Mounting — Snap-in terminal, radial can snap-in package for secure board mounting; physical dimensions: φ22 × 30 L (height seated max 1.181 inch), polarization per standard electrolytic design.
• Operating Range & Shelf Life — Rated for operation from −25°C to +105°C; shelf-life and recovery characteristics are specified (1000 h at 105°C storage with post-treatment limits defined).
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High-Voltage Power Supplies — Bulk filtering and energy storage in 400–450 V class power supplies and DC–DC converters where 420 V rating and high ripple capability are required.
• Industrial Equipment — Use in industrial control and power systems that operate in environments with voltage fluctuations, taking advantage of the part’s endurance at 105°C and safety provisions.
• Inverters and Power Conversion — Filtering and smoothing in inverter and converter stages that demand high-voltage capacitance and reliable ripple-current performance across frequency ranges.
• General Purpose High-Voltage Circuits — Applications requiring a compact, snap-in electrolytic capacitor for radial mounting and polarized high-voltage bulk capacitance.

Unique Advantages

• Compact high-voltage solution: φ22 × 30 L case delivers 82 µF at 420 V in a smaller case size compared with older series, enabling denser board layouts.
• Extended high-temperature life: Rated to endure 2000 hours at 105°C with defined limits for capacitance change and leakage, supporting long-term reliability in hot environments.
• Robust ripple handling: High rated ripple currents (640 mA at 120 Hz, 736 mA at 10 kHz) and frequency coefficients allow accurate thermal and ripple sizing across application frequencies.
• Designed for voltage fluctuation: Improved safety against abnormally excessive voltage and a pressure relief vent built to operate without dangerous failure modes under test conditions.
• Clear qualification metrics: Endurance and shelf-life specifications (capacitance, tan δ and leakage limits) provide measurable criteria for design verification and lifecycle planning.
• Regulatory compliance: RoHS conformity simplifies environmental compliance for deployed systems.
