LASW6221MELB35

The LASW6221MELB35 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It provides 220 µF capacitance at a rated 420 V in a compact φ30×35L radial can package and is built for robust ripple-current endurance at elevated temperature.

Key value propositions include high-temperature endurance (2000 hours at 105°C under rated ripple current), improved safety for abnormally excessive voltage, and RoHS compliance—making it well suited to equipment operating in environments with fluctuating voltages.

Key Features

• Capacitance and Voltage — 220 µF rated capacitance at 420 V for bulk smoothing and energy storage in high-voltage circuits.
• High-temperature Endurance — Specified to withstand 2000 hours with rated ripple current at 105°C, supporting long-term operation under elevated thermal stress.
• Ripple Current Performance — Rated ripple current of 1 A at 120 Hz and 1.15 A at 10 kHz, with frequency coefficients that increase ripple handling at higher frequencies.
• Safety and Abnormal Voltage Tolerance — Improved safety features with a pressure relief vent and permissible abnormal voltage characteristics to mitigate hazardous failure modes.
• Package and Mounting — Snap-in terminal radial can (φ30×35L, L: 3.5 × D: 3 cm) for secure, board-level mounting in power modules and capacitor banks.
• Temperature Range and Stability — Operating temperature range of −25°C to +105°C; capacitance tolerance ±20% (120 Hz, 20°C) and tan δ 0.20 max at 120 Hz, 20°C.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Electrical Equipment — Suitable where a robust, high-voltage electrolytic capacitor is required for general-purpose power circuitry.
• Equipment in Voltage-Fluctuating Areas — Designed specifically for systems exposed to fluctuating line voltages due to its improved safety features and abnormal-voltage tolerance.
• High-Temperature Power Modules — Appropriate for power assemblies that must maintain ripple-current endurance and capacitance stability at up to 105°C.

Unique Advantages

• Long-Term High-Temperature Endurance: 2000-hour rated endurance at 105°C under rated ripple current supports reliable service life in demanding thermal environments.
• Improved Abnormal-Voltage Safety: Pressure relief vent and enhanced safety design reduce the risk of dangerous conditions under excessive voltage events.
• Compact Snap-In Form Factor: φ30×35L radial can with snap-in terminals enables secure mounting and space-efficient board-level installation.
• Frequency-Responsive Ripple Handling: Defined ripple current values (1 A at 120 Hz, 1.15 A at 10 kHz) and frequency coefficients ensure predictable performance across common ripple spectra.
• RoHS Compliance: Meets RoHS requirements for restricted substances, aiding regulatory alignment for EU markets.
