LASW6181MELA40

The LASW6181MELA40 is a Nichicon aluminum electrolytic capacitor in a snap-in terminal, radial can package rated 180 µF at 420 V. Designed for general-purpose power applications, it delivers high-voltage capacitance with compact dimensions (φ25 × 40 mm) and tray packing for mass production.

Built for demanding operating conditions, this part offers endurance at elevated temperature and engineered safety features to address environments with voltage fluctuation, providing stable performance for industrial and equipment-level power systems.

Key Features

• Electrical rating — 180 µF nominal capacitance at a 420 V rated voltage, ±20% tolerance.
• High-temperature endurance — Qualified for 2000 hours at 105°C when subjected to DC bias plus rated ripple current; capacitance and leakage remain within specified limits after endurance.
• Ripple current capability — Rated ripple current of 900 mA at 120 Hz and 1.035 A at 10 kHz, with frequency coefficients allowing higher ripple endurance at elevated frequencies.
• Wide operating temperature — Specified for use from −25°C to +105°C to accommodate a range of thermal environments.
• Safety and reliability — Improved safety features and a pressure relief vent designed to operate under abnormal voltage conditions, reducing risk of dangerous failure modes.
• Package and mounting — Snap-in terminal, radial can (φ25 × 40 mm) optimized for secure board mounting and automated assembly (tray packing for mass production).
• RoHS compliant — Meets RoHS directive requirements.

Typical Applications

• General-purpose power equipment — Bulk smoothing and energy storage in systems where reliable high-voltage capacitance is required.
• Equipment operating in fluctuating-voltage environments — Designed and tested for use in applications exposed to abnormal voltage conditions, offering improved safety performance.
• Industrial power systems — Suitable where higher ripple current handling and elevated-temperature endurance (2000 h at 105°C) are needed.

Unique Advantages

• Long endurance at elevated temperature: 2000 hours at 105°C under rated ripple and bias preserves capacitance and leakage characteristics for extended service life.
• Designed for voltage fluctuation: Improved safety features and pressure relief vent operation help mitigate abnormal-voltage events.
• Compact snap-in form factor: φ25 × 40 mm radial can with snap-in terminals supports robust board mounting and production handling.
• Frequency-aware ripple performance: Specified ripple current values with frequency coefficients allow designers to predict ripple handling across common operating bands.
• Regulatory compliance: RoHS compliance supports environmental and manufacturing requirements.
