LAQ2P181MELA25ZB

The LAQ2P181MELA25ZB is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It combines a compact 25 mm × 25 mm can with a 220 V rated voltage and 180 µF capacitance to deliver bulk energy storage and filtering in equipment that requires robust ripple handling and high-temperature endurance.

With an operating range from −25°C to +105°C and 2000 hours endurance at 105°C, this capacitor is intended for applications that demand stable performance under continuous thermal and electrical stress.

Key Features

• Electrical Performance: 180 µF capacitance at 220 V rated voltage; capacitance tolerance ±20% (120 Hz, 20°C), suitable for bulk filtering and energy storage.
• High Ripple Capability: Rated ripple current 700 mA at 120 Hz and 840 mA at 10 kHz, enabling effective suppression of AC ripple in power circuits.
• Leakage and Loss Characteristics: Low leakage current (specified 0.59 mA) and tangent of loss angle (tan δ) ≤ 0.20 at 20°C, 120 Hz for predictable leakage and dissipation behavior.
• Thermal Endurance: Rated for −25°C to +105°C operation with 2000 hours endurance at 105°C when subjected to DC bias plus rated ripple current, providing long-term stability under elevated temperatures.
• Package & Mounting: Snap-in radial can (25 mm diameter × 25 mm length) for secure panel or board mounting and quick installation in mass-production assemblies; tray packing for efficient handling.
• Safety Design: Series-level safety features include a pressure relief vent that operates under abnormal conditions to reduce risk of flame or dangerous dispersion.
• Regulatory: LAQ series is stated as compliant with the RoHS directive (2011/65/EU, (EU)2015/863), addressing restricted substance requirements.

Typical Applications

• General-purpose power circuits — Bulk smoothing, decoupling and energy storage in general-purpose power supplies and control modules.
• Industrial equipment — Filtering and ripple management in industrial control and power conversion equipment where elevated temperature endurance is required.
• Stationary power electronics — Support for DC bus stabilization and transient suppression in stationary power systems and auxiliary power units.

Unique Advantages

• High-temperature endurance: 2000 hours at 105°C provides predictable life performance for designs exposed to sustained elevated temperatures.
• Robust ripple handling: 700 mA (120 Hz) and 840 mA (10 kHz) ripple ratings reduce heating and extend service life in high-ripple environments.
• Compact snap-in form factor: 25 mm × 25 mm can and snap-in terminals simplify mechanical integration while supporting secure mounting for high-volume production.
• Defined electrical characteristics: Specified tan δ, leakage, and tolerance values enable accurate design margining and predictable circuit behavior.
• Built-in safety features: Pressure relief vent design mitigates abnormal-voltage risks without introducing complex external protection schemes.
