LAQ2G221MELA45ZB

The LAQ2G221MELA45ZB is a snap-in terminal aluminum electrolytic capacitor offering 220 µF capacitance at a 400 V rating. It delivers a combination of high-voltage capability and compact snap-in packaging for general-purpose power applications.

Designed for continuous operation from -25°C to 105°C with a rated endurance of 2000 hours at 105°C, this part targets applications that require reliable high-voltage smoothing and ripple handling in a compact φ25 × 45 mm can with tray packing for volume production.

Key Features

• Core electrical performance — 220 µF capacitance with a 400 V rated voltage and ±20% tolerance, polarized for DC applications.
• Ripple current capability — Handles 1.24 A at 120 Hz and 1.426 A at 10 kHz, enabling effective ripple smoothing under rated conditions.
• Low leakage — Specified leakage current of 0.88 mA to help minimize standby losses in DC circuits.
• Thermal and endurance — Rated operating temperature range of -25°C to 105°C with 2000 hours endurance at 105°C under D.C. bias plus rated ripple current.
• Package and mounting — Snap-in terminal, radial can (φ25 × 45 mm) for secure board mounting and tray packing suited to mass production.
• Safety and reliability — Includes pressure relief venting as specified for the LAQ series to mitigate abnormal internal pressure events.

Typical Applications

• General-purpose power electronics — Bulk capacitance and 400 V rating support DC smoothing and decoupling in high-voltage power rails where polarized electrolytics are required.
• High-voltage DC circuits — Suited to circuits requiring 400 V working voltage combined with sustained ripple current handling.
• Industrial power modules — Endurance at 105°C and tray packaging make the part appropriate for production deployment in industrial power assemblies.
• Energy storage and smoothing — 220 µF capacitance and specified ripple capability help stabilize supply voltages in energy buffering applications.

Unique Advantages

• High-voltage capability: 400 V rating supports designs with elevated DC bus voltages without the need for series stacking.
• Measured ripple performance: Rated ripple currents at 120 Hz and 10 kHz (1.24 A and 1.426 A) provide quantifiable handling for designers targeting specific ripple budgets.
• Long endurance at elevated temperature: 2000 hours at 105°C under rated conditions provides predictable lifetime behavior for thermal-stressed applications.
• Compact snap-in package: φ25 × 45 mm radial snap-in can enables secure PCB mounting while conserving board area compared with larger cans.
• Low leakage: 0.88 mA leakage current helps reduce no-load energy dissipation in DC systems.
• Production-ready packaging: Tray packing supports automated assembly and higher-volume manufacturing workflows.
