LAQ2P221MELA25ZB

The LAQ2P221MELA25ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series, offering 220 µF capacitance at a 220 V rated voltage in a compact φ25 × 25 mm can. Designed for general-purpose electronic equipment, it provides polarized bulk capacitance in a radial snap-in package suitable for board-mounted power designs.

Key value propositions include robust ripple-current handling (900 mA at 120 Hz and 1.08 A at 10 kHz), a wide operating temperature range of −25°C to +105°C, low leakage current (660 µA), and a 2000-hour endurance rating at 105°C — all supplied in tray packing and in mass production.

Key Features

• Capacitance & Tolerance — 220 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage — 220 V DC for higher-voltage general-purpose applications.
• Temperature Range & Endurance — Operates from −25°C to +105°C with a rated life of 2000 hours at 105°C under specified test conditions.
• Ripple Current Handling — 900 mA at 120 Hz (low frequency) and 1.08 A at 10 kHz (high frequency) to manage AC stress during operation.
• Low Leakage & Safety — Leakage current 660 µA and built-in pressure-relief venting as described for the LAQ series to support safer operation.
• Package & Mounting — Radial, can-type snap-in terminal; compact footprint φ25 × 25 mm; supplied in tray packing for production assembly.
• Regulatory Status — RoHS compliant and available in mass production.

Typical Applications

• General-purpose power supplies — Bulk smoothing and decoupling where a polarized 220 µF, 220 V capacitor is required.
• Industrial power modules — Local energy buffering and ripple attenuation in equipment operating up to 105°C.
• Electronic assemblies with snap-in mounting — Board-mounted radial applications that benefit from a compact φ25 × 25 mm snap-in can.

Unique Advantages

• High-voltage capability: 220 V rating supports designs that require elevated DC bus voltages.
• Compact snap-in form factor: φ25 × 25 mm radial can saves PCB space while providing secure mechanical mounting.
• Robust ripple tolerance: Dual-frequency ripple ratings (900 mA at 120 Hz, 1.08 A at 10 kHz) help manage thermal and electrical stress under AC loading.
• Extended high-temperature endurance: 2000 hours at 105°C with specified retention limits gives predictable performance in elevated-temperature applications.
• Low leakage and safety venting: Low leakage current (660 µA) combined with pressure-relief vent behavior supports reliable long-term operation.
• Production-ready supply: RoHS compliant, tray-packed and in mass production for streamlined procurement and assembly.
