LAQ2P331MELA30ZB

The LAQ2P331MELA30ZB is a Nichicon LAQ series aluminum electrolytic capacitor in a snap-in terminal package. It delivers 330 µF nominal capacitance at a 220 V rating with a polar design and compact φ25×30L form factor.

Engineered for general-purpose applications, this capacitor offers a combination of high ripple handling, defined endurance at elevated temperature, and stable electrical characteristics suitable for industrial and commercial equipment designs that require reliable bulk capacitance on a 220 V rail.

Key Features

• Electrolytic Core: 330 µF capacitance with ±20% tolerance (120 Hz, 20°C), providing predictable bulk energy storage for high-voltage rails.
• Voltage Rating: 220 V rated voltage suitable for applications within the LAQ series rated range.
• Snap-in Mounting: Radial, can-type snap-in package for secure mechanical retention in through-hole assemblies.
• High Ripple Capability: 1.2 A ripple current at 120 Hz (low frequency) and 1.44 A at 100 kHz (high frequency), supporting designs with significant AC ripple on DC rails.
• Low Loss: tan δ ≤ 0.20 at 20°C, 120 Hz, for controlled dissipation and thermal behavior under AC conditions.
• Leakage Current: Specified leakage current of 800 µA, enabling predictable standby and leakage behavior after voltage application.
• High-Temperature Endurance: Rated for 2000 hours at 105°C under DC bias plus rated ripple current, with defined limits for capacitance change, tan δ, and leakage.
• Temperature Range: Operates from −25°C to +105°C to accommodate a wide range of environmental conditions.
• Compact Dimensions: φ25 × 30 mm size (L: 3.0 cm × D: 2.5 cm) for space-conscious power assemblies.

Typical Applications

• General-purpose equipment: Designed for systems that require a 220 V, 330 µF snap-in electrolytic with robust ripple handling and 2000 h endurance at 105°C.
• Power rail bulk capacitance: Provides bulk energy storage and smoothing where sustained ripple currents (1.2 A @120 Hz / 1.44 A @100 kHz) are present.
• Industrial and commercial assemblies: Suitable where a compact, snap-in, polar aluminum electrolytic is needed with defined leakage and loss-angle characteristics.

Unique Advantages

• Rated for 220 V operation: Enables use on higher-voltage DC rails within the LAQ series rating set.
• Measured ripple performance: Dual-frequency ripple ratings (120 Hz and 100 kHz) give designers clear limits for both low- and high-frequency applications.
• Long-term thermal reliability: 2000 hours endurance at 105°C under specified conditions supports sustained operation in hot operating environments.
• Predictable electrical behavior: ±20% capacitance tolerance and tan δ ≤ 0.20 at 20°C, 120 Hz provide stable, specified performance for design margining.
• Snap-in package convenience: Radial snap-in can simplifies PCB retention and mechanical assembly for through-hole designs.
