LAQ2P181MELZ25

The LAQ2P181MELZ25 is an aluminum electrolytic capacitor from Nichicon's LAQ series featuring a snap-in terminal radial can. It provides 180 µF capacitance at a 220 V rating in a compact φ22 × 25 mm package intended for general-purpose electronic applications.

Designed for elevated-temperature operation, this part offers 2000 hours endurance at 105°C, combined with specified ripple current performance and low leakage for reliable bulk capacitance and smoothing in a range of systems.

Key Features

• Capacitance and Tolerance — 180 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C) for predictable bulk energy storage.
• Rated Voltage — 220 V DC rating suitable where higher-voltage bulk capacitance is required.
• High-Temperature Endurance — Qualified for 2000 hours at 105°C under rated conditions, with defined limits for capacitance change, tan δ and leakage after endurance testing.
• Ripple Current Capability — 700 mA at 120 Hz (low frequency) and 840 mA at 10 kHz (high frequency) to handle AC ripple on DC buses within specified limits.
• Low Leakage — Specified leakage current of 0.59 mA after rated voltage application, supporting efficient system idle-current characteristics.
• Snap-in Radial Can — Snap-in terminal mounting for secure board retention and straightforward assembly in mass-production trays.
• Operating Temperature Range — Rated for −25°C to +105°C to support higher ambient and internal case temperatures.
• Built-in Safety Vent — Pressure relief vent designed to operate under abnormal conditions, reducing risk of flame or dispersion of parts.

Typical Applications

• General-purpose electronic systems — Provides bulk capacitance and smoothing where a 180 µF, 220 V polarized capacitor is specified.
• Power modules and supplies — Used where elevated-temperature endurance (2000 h at 105°C) and defined ripple current handling are required.
• Industrial equipment — Suitable for designs that require compact, snap-in high-voltage capacitance in a radial can package.

Unique Advantages

• Compact high-voltage bulk capacitance: 180 µF at 220 V in a φ22 × 25 mm can saves board space while delivering substantial charge storage.
• Robust high-temperature performance: 2000-hour endurance at 105°C supports long-term stability in hot operating environments.
• Defined ripple handling: 700 mA (120 Hz) and 840 mA (10 kHz) ratings provide clear design margins for filtering and smoothing tasks.
• Low leakage current: 0.59 mA leakage specification helps preserve system efficiency and predictable behavior after voltage application.
• Secure snap-in mounting: Radial snap-in terminals aid reliable mechanical retention for mass-production assembly.
• Safety-focused construction: Pressure relief vent operation reduces the risk associated with abnormal voltage events.
