LAS2G221MELB30ZB

The LAS2G221MELB30ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power electronics. It offers 220 µF capacitance at a 400 V rating in a compact φ30 × 30 mm can with radial snap‑in mounting and tray packing for production assembly.

Engineered for demanding operating environments, this part delivers high ripple current capability, proven endurance at elevated temperature, and safety features suitable for applications exposed to fluctuating voltages.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 400 V with ±20% tolerance (120 Hz, 20°C) for bulk energy storage and filtering.
• High Temperature Endurance — Specified for 2000 hours at 105°C under rated conditions to support long‑life operation in hot environments.
• Ripple Current Performance — 1.24 A at 120 Hz (low frequency) and 1.426 A at 10 kHz (high frequency) to handle both mains and high‑frequency switching ripple.
• Loss and Leakage — Maximum tan δ of 0.20 at 20°C/120 Hz and a leakage current of 880 µA, supporting stable electrical performance over time.
• Safety Vent — Built‑in pressure relief vent for safer behavior under abnormal overvoltage conditions as described in the LAS series documentation.
• Package & Mounting — Radial, snap‑in can (φ30 × 30 mm) suited for snap‑in PCB mounting and tray packing for volume production.
• Temperature Range & Compliance — Rated for −25°C to +105°C and RoHS compliant.

Typical Applications

• Switch‑Mode Power Supplies (SMPS) — Bulk filtering and energy storage at high DC bus voltages, benefiting from the 400 V rating and high ripple current capability.
• Industrial Power Conversion — Input/output smoothing for inverters and converters operating in environments with voltage fluctuation and elevated temperatures.
• Motor Drives & Power Modules — DC link and smoothing roles where sustained ripple current handling and long endurance at 105°C are required.
• General‑Purpose High‑Voltage Filtering — Applications that require robust high‑voltage capacitors for transient and ripple suppression in production systems.

Unique Advantages

• High Voltage Capability: 400 V rating enables use on high‑voltage rails without additional series components.
• Robust Ripple Handling: Specified ripple currents at both low and high frequency (1.24 A @120 Hz, 1.426 A @10 kHz) reduce the need for parallel capacitors for many designs.
• Extended High‑Temperature Life: 2000 hours at 105°C provides predictable endurance for industrial and power applications.
• Compact Snap‑in Form Factor: φ30 × 30 mm radial can with snap‑in terminals simplifies PCB mounting for power assemblies.
• Safety‑Oriented Design: Pressure relief vent operation mitigates risk during abnormal overvoltage events as described in the LAS series specifications.
• Regulatory Compliance: RoHS compliant for use in regulated production environments.
