LAQ2P331MELZ40ZB

The LAQ2P331MELZ40ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LAQ series. It delivers 330 µF capacitance at a 220 V rating in a compact φ22 × 40 mm can designed for general-purpose applications.

Engineered for high-temperature endurance and reliable ripple handling, this polarized radial snap-in capacitor targets power assemblies and equipment that require robust bulk capacitance in a compact, serviceable package.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with ±20% tolerance at 220 V rated voltage, specified at 120 Hz and 20°C.
• High-Temperature Endurance — Rated for operation from -25°C to +105°C with an endurance specification of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Performance — Low-frequency ripple current of 1.2 A (120 Hz) and high-frequency ripple current of 1.44 A (10 kHz), supporting sustained ripple handling in power circuits.
• Low Leakage — Typical leakage current specified at 800 µA; datasheet also specifies leakage limits and post-test leakage behavior.
• Snap-In Radial Can Package — Snap-in terminal, radial can construction (φ22 × 40 mm) for secure mechanical retention and easy assembly into power modules or chassis-mounted boards.
• Safety Design — Pressure relief vent designed to operate under abnormal conditions without dangerous flames or dispersion of casing parts, per series safety performance guidance.

Typical Applications

• General-purpose power assemblies — Designed for general-purpose capacitor roles in power equipment where 220 V, 330 µF bulk capacitance is required.
• Industrial and commercial electronics — Suitable for applications that require a compact snap-in electrolytic capacitor with specified ripple and high-temperature endurance.
• Mass-production assemblies — Supplied in tray packing for production volumes and repeatable assembly processes.

Unique Advantages

• Compact, high-capacitance form factor: 330 µF in a φ22 × 40 mm can provides substantial bulk capacitance while minimizing board footprint.
• Rated for elevated temperatures: 2000-hour endurance at 105°C offers predictable performance in high-temperature operating environments.
• Defined ripple capability: Specified ripple currents at both low (1.2 A at 120 Hz) and high (1.44 A at 10 kHz) frequencies enable reliable performance under different ripple spectra.
• Reliable leakage characteristics: Leakage current specified (800 µA) with established post-test limits helps designers budget standby and loss currents accurately.
• Snap-in mounting for secure installation: Radial snap-in terminals simplify mechanical retention and are suitable for power module assemblies.
• Manufacturing-ready packaging: Tray packing supports automated handling and high-volume production workflows.
