LAQ2P181MELA25

The LAQ2P181MELA25 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAQ series, offering 180 µF capacitance at a 220 V rating. Designed for general‑purpose high‑voltage applications, it combines a compact φ25 × 25 mm can with snap‑in mounting for secure PCB installation and efficient use of board space.

Key performance characteristics include a wide operating temperature range of −25°C to 105°C, a rated endurance of 2000 hours at 105°C, and RoHS compliance, making it suitable for sustained operation in demanding commercial and industrial equipment.

Key Features

• Core Electrical — 180 µF nominal capacitance with a 220 V rated voltage and ±20% tolerance, providing energy storage and decoupling for medium‑voltage DC circuits.
• Loss and Leakage — Low loss characteristics with tanδ (DF) ≤ 0.20 measured at 20°C, 120 Hz, and a specified leakage current of 590 µA for predictable performance after voltage application.
• Ripple Current Performance — Rated ripple current of 700 mA at 120 Hz (low frequency) and 840 mA at 10 kHz (high frequency) to support filtering under AC or pulsating DC stress.
• Temperature and Endurance — Operating range −25°C to 105°C with an endurance rating of 2000 hours at 105°C under rated DC bias plus ripple current, supporting long‑term deployment in elevated temperatures.
• Package & Mounting — Radial can, snap‑in terminal package (φ25 × 25 mm) for robust board retention and ease of assembly in power modules and chassis‑mounted designs.
• Safety and Reliability — Series design includes pressure relief venting for safe operation under abnormal conditions; the product is in mass production and RoHS compliant.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling in 220 V DC rails where 180 µF capacitance and high ripple capability are required.
• Industrial equipment — Power electronics and control assemblies operating up to 105°C that require long endurance (2000 h) and stable electrical characteristics.
• Compact high‑voltage assemblies — Designs that need a smaller footprint while maintaining snap‑in mechanical retention and reliable high‑voltage performance.

Unique Advantages

• High voltage capability: 220 V rating enables use in medium‑voltage DC circuits without series stacking.
• Compact snap‑in package: φ25 × 25 mm radial can with snap‑in terminals for secure PCB mounting and space‑efficient layouts.
• Designed for elevated temperatures: Rated for −25°C to 105°C with a 2000 h endurance at 105°C for sustained performance in hot environments.
• Measured ripple performance: Defined ripple current values at both 120 Hz and 10 kHz allow designers to account for low‑ and high‑frequency stress in filtering applications.
• Predictable electrical behavior: Specified tanδ ≤ 0.20 at 20°C/120 Hz and a documented leakage current value support predictable circuit design and sizing.
• Production readiness and compliance: Mass production status and RoHS compliance simplify procurement and regulatory tracking.
