LAQ2D181MELA20

The LAQ2D181MELA20 is a Nichicon LAQ series snap-in terminal aluminum electrolytic capacitor specified at 180 µF and 200 V. Designed for general-purpose power applications, this radial can provides compact bulk capacitance with high ripple-handling capability in a smaller-sized snap-in package.

Key value comes from a combination of high voltage rating, robust ripple current performance (different values at low and high frequency), low leakage, and a 2000-hour endurance at elevated temperature for reliable operation in sustained-power environments.

Key Features

• Capacitance & Tolerance — 180 µF with ±20% tolerance at 120 Hz, 20°C, suitable for bulk energy storage and smoothing in power circuits.
• Rated Voltage — 200 V DC rating to support higher-voltage power rails and filtering applications.
• Snap-in Radial Package — Snap-in terminal, radial can package sized φ25 × 20 mm (diameter × length) for secure mounting and compact board footprint.
• Ripple Current Capability — 700 mA at 120 Hz (low frequency) and 840 mA at 10 kHz (high frequency) to handle AC ripple across a range of operating conditions.
• Low Leakage — Rated leakage current of 0.56 mA, supporting predictable bias behavior in power designs.
• Wide Operating Temperature — Rated for −25°C to +105°C to meet temperature demands in many industrial and commercial environments.
• Endurance — 2000 hours at 105°C under DC bias plus rated ripple current with capacitance change within ±20% and leakage current meeting initial specification after the test.
• Safety Vent — Pressure relief vent design specified to operate under abnormal conditions to prevent hazardous failures.

Typical Applications

• Power supply smoothing — Bulk filtering and energy storage on medium- to high-voltage rails where 200 V rating and 180 µF capacitance are required.
• General-purpose power electronics — Decoupling and bulk capacitance in industrial and commercial power circuits that require robust ripple handling.
• Standby/hold-up support — Short-term energy storage to support hold-up or transient conditions in power systems.

Unique Advantages

• High-voltage capability: 200 V rating enables use on elevated DC rails without parallel components.
• Dual-frequency ripple performance: Specified ripple current at both 120 Hz (700 mA) and 10 kHz (840 mA) provides predictable behavior across common ripple spectra.
• Compact snap-in form factor: φ25 × 20 mm package gives substantial capacitance in a smaller footprint for space-constrained assemblies.
• Long endurance at elevated temperature: 2000-hour endurance at 105°C under rated conditions supports sustained reliability in higher-temperature environments.
• Controlled leakage: Low leakage current (0.56 mA) helps maintain bias stability and predictable discharge characteristics.
• Safety-focused construction: Pressure relief venting reduces risk during abnormal voltage or thermal events.
