LASW6221MELC30ZB

The LASW6221MELC30ZB is a snap-in terminal type aluminum electrolytic capacitor designed for high-voltage, high-ripple applications. It delivers 220 µF at a 420 V rating in a compact φ35×30 mm can and is built for equipment that experiences voltage fluctuations.

This part is optimized for endurance and safety: it withstands 2000 hours of rated ripple current at 105°C, offers improved safety features for abnormally excessive voltage, and is RoHS compliant.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 420 V rated voltage and ±20% tolerance.
• High-temperature Endurance — Rated to operate from −25°C to +105°C with an endurance specification of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Performance — Specified ripple current of 1.00 A at 120 Hz and 1.15 A at 10 kHz, with series frequency coefficients that increase allowed ripple at higher frequencies.
• Snap-in Can Package — Radial, snap-in terminal configuration (φ35×30 mm) for secure mounting in power assemblies.
• Enhanced Safety Design — Pressure-relief vent and improved safety features to mitigate risks under abnormally excessive voltage conditions.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk filtering and energy smoothing in high-voltage AC/DC and DC/DC power conversion under fluctuating line conditions.
• Uninterruptible Power Supplies (UPS) and Energy Storage — Energy reservoir and ripple handling where long-term high-temperature endurance is required.
• Motor Drives and Inverters — DC link and smoothing in equipment exposed to variable voltages and high ripple currents.
• Heavy-duty Electronic Equipment — General-purpose decoupling and filtering in industrial equipment operating up to 420 V and elevated ambient temperatures.

Unique Advantages

• High-voltage capability: 420 V rating enables use in higher-voltage power designs without series stacking.
• Designed for long ripple endurance: 2000 hours at 105°C under rated ripple current provides predictable lifetime performance in demanding thermal environments.
• Compact snap-in package: φ35×30 mm can offers smaller case sizing compared to similar series (LAQ), helping reduce overall board footprint.
• Improved safety features: Pressure-relief venting and specific design measures reduce hazardous failure modes under excessive voltage conditions.
• Frequency-aware ripple handling: Ripple current specification and frequency coefficients allow engineers to size parts for both low- and high-frequency ripple environments.
• Regulatory compliance: RoHS compliance supports use in equipment requiring restricted-substance adherence.
