UAS2D181MHD6

The UAS2D181MHD6 is a miniature aluminum electrolytic capacitor from Nichicon’s UAS series, configured as a radial‑lead polarized device with a rated capacitance of 180 µF and a rated voltage of 200 V. It combines a compact φ18 × 25 mm can with a wide operating temperature range and series-level safety features to meet general‑purpose electronic requirements.

Designed for applications that require elevated ripple handling and extended high‑temperature endurance, this part offers specified ripple currents at both low and high frequencies and a lifecycle rating of 2000 hours at 105°C. Packaging options include bulk (no terminal forming) and bag packing, and the product is RoHS compliant and in mass production.

Key Features

• Electrical Performance — 180 µF capacitance at a rated voltage of 200 V with a tolerance of −20% to +20% and a dissipation factor (tanδ) of 0.15 (measured at 20°C, 120 Hz).
• Ripple Current Capability — Rated low‑frequency ripple current of 600 mA at 120 Hz and high‑frequency ripple current of 960 mA at 10 kHz, supporting demanding AC ripple conditions within specified frequencies.
• Leakage and Polarization — Polarized aluminum electrolytic design with a specified leakage current of 1540 µA (measured after 1 minute at 20°C under rated voltage conditions as per series specifications).
• Mechanical & Lead Details — Radial lead package in a φ18 × 25 mm can with lead spacing of 7.5 mm (±0.5 mm), suitable for through‑hole mounting and manual or automated insertion processes.
• Temperature & Endurance — Wide operating temperature range from −40°C to +105°C and an endurance rating of 2000 hours at 105°C under DC bias plus rated ripple current.
• Safety & Series Design — UAS series design includes improved safety features for abnormal overvoltage conditions and a pressure relief vent intended to operate without hazardous flame or dispersion under fault conditions.
• Compliance & Availability — RoHS compliant, available in bulk or bag packing, and currently in mass production.

Typical Applications

• General‑Purpose Power Supplies — 200 V rating and 180 µF capacitance provide energy storage and smoothing for a wide range of electronic power rails and DC link circuits.
• Industrial Electronics — Wide temperature range (−40°C to +105°C) and 2000‑hour endurance at 105°C make it suitable for industrial equipment where sustained thermal performance is required.
• High‑Ripple Environments — Specified ripple currents (600 mA at 120 Hz and 960 mA at 10 kHz) address circuits subject to significant AC ripple across the capacitor.

Unique Advantages

• Compact, High‑Voltage Form Factor — φ18 × 25 mm can provides a space‑efficient option for a 200 V, 180 µF electrolytic capacitor.
• Frequency‑Aware Ripple Performance — Separate low‑ and high‑frequency ripple current specifications allow designers to match capacitor selection to the operating ripple spectrum.
• Robust High‑Temperature Endurance — 2000 hours at 105°C under rated conditions supports reliable operation in thermally demanding installations.
• Safety Features from Series Design — UAS series includes measures for permissible abnormal voltage and a pressure relief vent to reduce risk in abnormal conditions.
• Through‑Hole Mounting Convenience — Radial lead configuration with defined lead spacing simplifies placement in legacy and mixed‑technology boards.
• Regulatory Compliance — RoHS compliance supports environmental and regulatory requirements for many designs.
