UAS2G470MHD

The UAS2G470MHD is a radial‑lead aluminum electrolytic capacitor in Nichicon’s UAS series, specified at 47 µF and 400 V. It is a miniature, wide‑temperature type designed for general‑purpose applications that require a polarized, high‑voltage electrolytic capacitor.

Key value propositions include high ripple current capability at both low and high frequencies, a broad operating temperature range from −40 °C to +105 °C, a 2000‑hour endurance at 105 °C, and built‑in safety measures for abnormal voltage conditions.

Key Features

• Electrical Rating: 47 µF capacitance with a 400 V rated voltage and ±20% tolerance, providing a defined, high‑voltage polarized solution.
• Loss and Leakage: Maximum tan δ of 0.15 (measured at 120 Hz, 20 °C) and specified leakage current reference (product listing: 852 µA), enabling predictable loss and leakage behavior.
• High Ripple Capability: Rated ripple current of 290 mA at 120 Hz (low frequency) and 464 mA at 10 kHz (high frequency), with frequency coefficients provided in the series datasheet.
• Wide Temperature Range: Operates from −40 °C to +105 °C to support designs that span a broad thermal envelope.
• Endurance: 2000 hours at 105 °C under rated conditions, with defined limits for capacitance change, tan δ, and leakage after the endurance test.
• Safety Features: Series includes permissible abnormal voltage design and a pressure relief vent to mitigate unsafe failure modes under abnormal voltage conditions.
• Package and Mounting: Radial lead, can package in φ16×25L case with 7.5 mm lead spacing; supplied in bulk/bag packaging for production use.
• Regulatory: RoHS compliant as stated in product data and series documentation.

Typical Applications

• General‑purpose electronics: Use where a 47 µF, 400 V polarized radial electrolytic capacitor is required for general purpose circuits.
• High‑voltage assemblies: Suitable for assemblies that require a 400 V rated aluminum electrolytic component with defined ripple handling.
• Wide‑temperature environments: Applications that must operate across −40 °C to +105 °C can leverage the UAS2G470MHD’s specified temperature range and 2000‑hour endurance.

Unique Advantages

• 400 V rating for high‑voltage designs: Provides a ready‑to‑use 400 V polarized capacitor option without additional derating for voltage class.
• Dual‑frequency ripple handling: Explicit ripple current ratings at 120 Hz and 10 kHz allow designers to size components for both low‑ and high‑frequency ripple conditions.
• Long endurance at elevated temperature: 2000‑hour life at 105 °C reduces the need for frequent replacements in heat‑stressed applications.
• Wide operating temperature window: −40 °C to +105 °C supports use across a broad range of environmental conditions.
• Integrated safety considerations: Permissible abnormal voltage design and a pressure relief vent add layers of safety for abnormal operating conditions.
• Production‑friendly packaging: Supplied in bulk/bag format for streamlined handling in mass production environments.
