LAQ2P471MELC25ZB

The LAQ2P471MELC25ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAQ series, specified for 220 V operation with 470 µF capacitance. It combines high ripple handling, a compact φ35 × 25 mm can, and an extended 2000‑hour endurance at 105°C for demanding general‑purpose power applications.

Designed for equipment exposed to voltage fluctuation and elevated temperatures, this polarized, radial snap‑in capacitor is optimized for smoothing, filtering and energy‑buffering roles in industrial and power‑electronics systems.

Key Features

• Rated Capacitance and Tolerance — 470 µF nominal capacitance with ±20% tolerance at 20°C and 120 Hz, providing predictable bulk energy storage for power systems.
• High Voltage Rating — 220 V rated voltage suitable for a range of industrial and power‑supply designs that require higher DC bus voltages.
• High Ripple Current Capability — 1.45 A at 120 Hz (low frequency) and 1.74 A at 10 kHz (high frequency), allowing effective filtering under real ripple conditions.
• Thermal and Endurance Performance — Rated for operation from −25°C to +105°C with endurance of 2000 hours at 105°C under DC bias plus rated ripple current, supporting long‑term operation in elevated temperature environments.
• Electrical Loss and Leakage — Low dissipation factor (tan δ) of 0.20 max at 20°C/120 Hz and a typical leakage current specified at 960 µA, enabling efficient charge/discharge behavior and controlled leakage under rated conditions.
• Snap‑in Radial Can Package — φ35 × 25 mm can with snap‑in terminals and tray packing for secure board mounting and assembly in high‑current power modules.
• Series Safety and Compliance — LAQ series features pressure relief venting and improved safety performance under abnormal voltage; the series is listed as compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk smoothing and filtering on high‑voltage DC rails where 220 V rated capacitance and sustained ripple current are required.
• DC/DC Converters and Inverters — Energy buffering and ripple attenuation in converters that operate at elevated temperatures and experience voltage fluctuation.
• Uninterruptible Power and Backup Systems — Capacitor banks and filtering stages that benefit from extended high‑temperature endurance and robust ripple handling.
• General Electronic Equipment — Applications requiring a compact, high‑voltage polarized capacitor for smoothing, decoupling or energy storage in industrial and commercial systems.

Unique Advantages

• High DC Voltage Handling: 220 V rating enables use on higher‑voltage rails without compromising capacitor life when applied within rated conditions.
• Strong Ripple Performance: Specified ripple currents of 1.45 A (120 Hz) and 1.74 A (10 kHz) reduce heating and improve lifecycle performance in high‑ripple environments.
• Compact Snap‑in Form Factor: φ35 × 25 mm can with snap‑in terminals provides a space‑efficient solution for board‑level power modules and assemblies.
• Long Endurance at Elevated Temperature: 2000 hours at 105°C under rated conditions provides predictable long‑term behavior for designs exposed to heat and continuous load.
• Controlled Electrical Losses and Leakage: tan δ ≤ 0.20 and specified leakage current (960 µA) support efficient operation and predictable standby losses.
• Series Safety Features: Pressure relief venting and design considerations for abnormal voltage enhance operational safety in fielded equipment.
