LAQ2P221MELZ30ZB

The LAQ2P221MELZ30ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LAQ series, offering 220 µF capacitance at a 220 V rating. It is a polarized, radial can design optimized for general-purpose power-electronic applications that require compact, high-voltage bulk capacitance.

With a rated operating range to 105°C, specified ripple-current ratings across low and high frequencies, a defined leakage current, and a 2000-hour endurance at 105°C, this part is suited for production use and comes packaged for tray handling in mass production environments.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 220 V rated voltage and ±20% tolerance, providing bulk energy storage for high-voltage circuits.
• Snap-in Radial Can Package — Snap-in terminal mounting in a radial can (φ22 × 30 mm) for secure board retention and simplified assembly in power modules and chassis-mounted PCBs.
• High-Temperature Endurance — Rated for operation from −25°C to +105°C with a 2000-hour endurance specification at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Capability — 900 mA ripple at 120 Hz (low frequency) and 1.08 A at 10 kHz (high frequency), supporting smoothing and decoupling workloads across common switching frequencies.
• Low Leakage — Specified leakage current of 660 µA, enabling predictable standby and bias characteristics after voltage application.
• Safety Vent Design — Series safety performance includes a pressure relief vent intended to operate without creating flames or dispersion of pieces of the capacitor/case under abnormal conditions.
• Production-Ready Packaging — Tray packing suitable for mass production and automated handling.

Typical Applications

• Power supply smoothing and bulk storage — Provides high-voltage bulk capacitance for DC bus smoothing and energy storage in switch-mode and linear power supplies.
• Industrial power electronics — Used in industrial controllers and power modules where elevated voltage and temperature endurance are required.
• Inverter and UPS systems — Supports ripple filtering and energy buffering in medium-voltage inverter stages and uninterruptible power supplies.

Unique Advantages

• 220 V rating for higher-voltage designs — Allows direct use in 200–220 V DC rails without series stacking, simplifying BOM and layout.
• Frequency-aware ripple performance — Separate ripple-current ratings at 120 Hz and 10 kHz let designers quantify thermal and lifetime stress across switching regimes.
• Long-term high-temperature durability — 2000 hours endurance at 105°C under rated conditions supports reliable operation in thermally demanding environments.
• Predictable leakage behavior — 660 µA specified leakage current enables consistent bias and discharge planning in power designs.
• Robust mechanical mounting — Snap-in radial can form factor provides stable PCB retention for chassis and board-mounted power assemblies.
