LAQ2G221MELA45

The LAQ2G221MELA45 is an aluminum electrolytic capacitor in a snap-in radial can package, rated 220 µF at 400 V with polarized terminals. It is part of Nichicon's LAQ series designed for smaller case sizes while delivering reliable performance in general-purpose electronic equipment.

Engineered for demanding thermal and voltage conditions, this capacitor is specified for operation from -25°C to +105°C, includes enhanced safety features for abnormally excessive voltage, and is suited for equipment exposed to fluctuating supply voltages.

Key Features

• Capacitance & Voltage: 220 µF rated at 400 V — provides bulk energy storage for high-voltage applications.
• Tolerance & Polarity: Capacitance tolerance is ±20% and the device is polarized, matching common power-electronic requirements.
• High-temperature Endurance: Rated operating range of -25°C to +105°C with an endurance specification of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current (frequency-specific): 1.24 A at 120 Hz and 1.426 A at 10 kHz — supports continued performance under applied ripple conditions across low and high frequencies.
• Compact Snap-in Package: Radial, can-type snap-in mounting for secure board attachment in space-constrained designs; size L: 4.5 × D: 2.5 cm.
• Improved Safety Features: Pressure relief vent design and series-level provisions for permissible abnormal voltage to reduce risk under excessive voltage conditions.
• Compliance: The LAQ series is compliant with the RoHS directive (2011/65/EU, (EU)2015/863) as documented in the series datasheet.

Typical Applications

• General-purpose electronic equipment: Bulk energy storage and smoothing in systems that require a high-voltage polarized capacitor.
• Equipment operating in fluctuating-voltage environments: Designed for use in applications where supply voltage may vary, leveraging the series' enhanced safety under abnormal voltage.
• High-temperature installations: Suitable for systems that must operate reliably up to 105°C with specified endurance under rated ripple and bias conditions.

Unique Advantages

• High-voltage, compact solution: 220 µF at 400 V in a smaller case size supports high-voltage designs where board space is limited.
• Rated high-temperature endurance: 2000 hours at 105°C under rated ripple current provides predictable lifetime behavior for thermal-stressed applications.
• Frequency-aware ripple performance: Published ripple current ratings at both 120 Hz and 10 kHz help designers size components for real-world AC ripple spectra.
• Snap-in mounting reliability: Radial snap-in terminals enable secure mechanical and electrical connection on PCBs for robust assembly.
• Safety under abnormal voltage: Series-level pressure relief and improved safety features reduce the likelihood of hazardous failure modes when exposed to excessive voltage.
• RoHS-compliant series: Meets RoHS directive requirements as documented for the LAQ series, supporting environmental compliance objectives.
