LAQ2P391MELC25ZB

The LAQ2P391MELC25ZB is a Nichicon LAQ series aluminum electrolytic capacitor in a snap-in terminal (radial can) package. It delivers 390 µF capacitance at a 220 V rating with ±20% tolerance and is designed for general-purpose power applications.

Built for durability and ripple-heavy environments, this part offers rated ripple current handling, extended 2000-hour endurance at 105°C, and a compact φ35 × 25 mm footprint for space-conscious assemblies and mass-production workflows.

Key Features

• Form Factor & Mounting — Snap-in terminal (radial, can - snap-in) package in tray packing, sized φ35 × 25 mm for robust mechanical retention and automated assembly.
• Capacitance & Voltage — 390 µF nominal capacitance with ±20% tolerance at a 220 V rated voltage for medium-voltage DC applications.
• Temperature Range & Endurance — Operates from −25°C to +105°C with an endurance rating of 2000 hours at 105°C when exposed to rated DC bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current of 1.35 A at 120 Hz (low frequency) and 1.62 A at 10 kHz (high frequency) to handle AC ripple on DC rails.
• Leakage Current — Specified leakage current of 0.87 mA after application of rated voltage.
• Safety & Series-Level Features — LAQ series includes improved safety features for abnormally excessive voltage (pressure relief vent behavior) and is listed as RoHS compliant in datasheet information.

Typical Applications

• General-purpose power filtering — Smoothing and bulk energy storage on 220 V DC rails where ripple handling and extended high-temperature endurance are required.
• Equipment subject to voltage fluctuation — LAQ series design and safety features suit applications operating in areas with voltage variation or transient stress.
• High-ripple DC bus sections — Use where rated ripple currents (1.35 A at 120 Hz / 1.62 A at 10 kHz) are necessary to maintain stable DC bus voltage.
• Production assemblies — Tray-packed, snap-in format supports mass-production placement and secure PCB retention for medium-voltage power assemblies.

Unique Advantages

• High ripple tolerance: Specified ripple currents at both low and high frequencies allow reliable operation in ripple-intensive circuits.
• Extended high-temperature life: 2000 hours at 105°C provides predictable performance and longevity under elevated operating temperatures.
• Compact snap-in package: φ35 × 25 mm can and snap-in terminals combine a small footprint with secure mounting for production environments.
• Built-in safety features: Series-level pressure relief and abnormally excessive voltage protections help mitigate hazardous failure modes.
• Compliance-conscious: Datasheet indicates RoHS directive compliance to support regulatory alignment in many markets.
