LAQ2P331MELZ40

The LAQ2P331MELZ40 is an aluminum electrolytic, snap-in terminal capacitor from Nichicon's LAQ series. It delivers 330 µF capacitance at a 220 V rated voltage in a compact φ22 × 40 mm can, designed for general-purpose power applications.

Built for equipment exposed to voltage fluctuations, this component combines elevated ripple handling, a wide operating temperature range, and series-level safety features to support robust power smoothing and filtering in production environments.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with ±20% tolerance at 220 V rated voltage.
• Ripple Current Performance — Rated ripple current of 1.2 A at 120 Hz (low frequency) and 1.44 A at 10 kHz (high frequency) to support sustained AC ripple conditions.
• Leakage Current — Specified leakage current of 800 µA for predictable DC behavior.
• Endurance & Temperature Range — Designed for 2000 hours endurance at 105°C and an operating temperature range of −25°C to +105°C.
• Package & Mounting — Snap-in radial can (φ22 × 40 mm), suited to through-hole, mechanically robust mounting; supplied in tray packing for mass-production assembly.
• Safety Features — LAQ series design includes a pressure relief vent and improved safety measures for abnormal over-voltage conditions.
• Compliance — The LAQ series is stated as compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power circuits — Bulk smoothing and filtering in equipment designated as general purpose where reliable DC bus decoupling is required.
• Equipment in voltage-fluctuating environments — Acts as a stable energy reservoir and ripple absorber in systems exposed to line or load variations.
• Production assemblies — Tray-packed snap-in format supports automated placement and high-volume manufacturing workflows.

Unique Advantages

• Robust ripple handling: 1.2 A (120 Hz) and 1.44 A (10 kHz) ratings provide margin for continuous AC ripple loads and mixed-frequency environments.
• High-temperature endurance: 2000 hours at 105°C gives predictable life performance for designs operating near elevated temperatures.
• Compact, snap-in package: φ22 × 40 mm can and snap-in terminals deliver a space-efficient through-hole solution with secure mechanical retention.
• Series-level safety design: Pressure relief venting and improved abnormal-voltage features reduce risk under overstress conditions.
• Production-ready packaging: Tray packing and mass-production availability simplify procurement and assembly planning.
• Regulatory alignment: RoHS compliance supports deployment in regions requiring restricted substances conformance.
