LASW6221MELA45

The LASW6221MELA45 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 220 µF capacitance at a 420 V rating in a compact φ25 × 45 mm can, optimized for equipment that operates in voltage‑fluctuating environments.

Engineered for high ripple endurance and elevated temperature operation, this Nichicon LAS series unit offers 2000 hours of rated ripple current endurance at 105°C and RoHS compliance for use in demanding industrial and power-conversion applications.

Key Features

• Electrical Performance: 220 µF nominal capacitance with ±20% tolerance and tanδ (DF) of 0.20 max measured at 20°C, 120 Hz, providing predictable filtering characteristics.
• High Voltage Rating: Rated for 420 V DC, suitable where elevated DC bus voltages are present.
• Ripple Current Capability: Supports 1.00 A at 120 Hz and 1.15 A at 10 kHz (frequency coefficient applied), enabling effective ripple handling across low and high frequency bands.
• Leakage Current: Specified leakage current of 910 µA, measured after rated voltage application at 20°C.
• Thermal and Endurance Specs: Operating temperature range of −25°C to +105°C with endurance of 2000 hours at 105°C under rated ripple/current conditions.
• Package & Mounting: Snap‑in terminal radial can (φ25 × 45 mm) for secure board mounting and tray packing for production handling.
• Safety Design: Improved safety features for abnormally excessive voltage and a pressure relief vent designed to operate without hazardous conditions.
• Regulatory Compliance: RoHS compliant and produced as a mass‑production part within the Nichicon LAS family.

Typical Applications

• General‑purpose power filtering: Bulk smoothing and ripple suppression in power conversion stages that require a 420 V rated capacitor with strong ripple capability.
• Equipment in voltage‑fluctuating areas: Designed with safety features and endurance to tolerate environments subject to abnormal voltage variations.
• High‑frequency ripple handling: Effective where high‑frequency ripple currents up to 1.15 A (at 10 kHz) must be managed alongside low‑frequency ripple.

Unique Advantages

• High ripple endurance: Rated ripple current and 2000‑hour endurance at 105°C support long service life under continuous ripple stress.
• Compact, serviceable form factor: φ25 × 45 mm snap‑in can provides a space‑efficient solution for board‑level power designs while enabling secure mounting.
• Elevated voltage capability: 420 V rating makes the part suitable for higher DC bus voltages without compromising capacitance.
• Built‑in safety measures: Pressure relief vent and improved safety features mitigate risks from abnormal overvoltage conditions.
• Verified performance metrics: Specified tanδ, leakage, and frequency‑dependent ripple coefficients allow predictable design margining.
• Regulatory readiness: RoHS compliance supports environmental requirements for commercial and industrial deployments.
