LAQ2D181MELA20ZB

The LAQ2D181MELA20ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAQ series designed for general‑purpose power electronics. It combines a 200 V rated voltage with 180 µF capacitance in a compact 25 mm × 20 mm can, delivering high ripple handling and long endurance for demanding thermal environments.

Engineered for systems that require reliable bulk filtering, smoothing and energy buffering, this polarized radial snap‑in capacitor offers a long 2,000‑hour life at 105°C, low leakage, and defined loss characteristics for predictable performance in assemblies.

Key Features

• Rated Performance — 180 µF capacitance at 200 V DC with ±20% tolerance, suitable for general‑purpose power applications.
• High Temperature Endurance — Rated for 2,000 hours at 105°C to support extended operation in elevated ambient conditions.
• Snap‑In Radial Can Package — 25 × 20 mm (φD × L) snap‑in terminal format for secure mounting and straightforward PCB integration.
• Ripple Current Handling — 700 mA at 120 Hz (low frequency) and 840 mA at 10 kHz (high frequency), enabling effective ripple smoothing across frequencies.
• Low Leakage and Loss — Leakage current of 0.56 mA and tan δ (DF) ≤ 0.20 at 20°C, 120 Hz for stable leakage and dissipation characteristics.
• Polarized, General‑Purpose — Polarized construction intended for DC power circuits and a wide operating range of −25°C to +105°C.
• Safety Design — Pressure relief venting per series specifications to mitigate abnormal conditions without dangerous failure modes.
• Production Ready Packaging — Tray packing and mass production availability for ease of manufacturing scale‑up.

Typical Applications

• General‑Purpose Power Electronics — Bulk energy storage and smoothing in power supply rails where a 200 V rating and 180 µF capacitance are required.
• Industrial Control Equipment — Filtering and ripple suppression in control power subsystems operating across a wide temperature range up to 105°C.
• Power Conversion Modules — DC link and smoothing duties benefitting from high ripple current capability at both low and high frequencies.

Unique Advantages

• Compact High‑Voltage Solution: 200 V rating in a 25 × 20 mm package permits space‑efficient design without sacrificing voltage margin.
• Designed for Elevated Temperatures: 2,000 hours life at 105°C provides predictable long‑term behavior in hot operating environments.
• Frequency Versatility: Specified ripple currents at 120 Hz and 10 kHz support use in both line‑frequency and switching environments.
• Stable Electrical Characteristics: Low leakage (0.56 mA) and controlled tan δ (≤ 0.20) yield reliable dissipation and predictable circuit performance.
• Robust Mounting: Snap‑in radial can construction simplifies assembly and secures the capacitor in high‑vibration or high‑current PCBs.
