UUN1H470MNJ1MS

The UUN1H470MNJ1MS is a chip-type, bi-polar aluminum electrolytic capacitor in Nichicon’s UUN series, designed for surface mounting on high-density PC boards. It provides a 47 µF capacitance at a 50 V rating with bi-polar operation and is targeted at general-purpose surface-mount applications where wide temperature performance and automated assembly compatibility are required.

This part is specified for operation across a wide temperature range of −55 °C to +105 °C, and is supplied in a tape-fed format suitable for automatic mounting machines. The device is RoHS compliant.

Key Features

• Capacitance & Voltage — 47 µF capacitance rated at 50 V with a tolerance of ±20% (120 Hz, 20 °C).
• Bi‑Polar Construction — Bi-polarized design allowing operation with polarity inversion as specified for the UUN series.
• Wide Temperature Range — Operating temperature from −55 °C to +105 °C supports use in thermally demanding environments.
• Endurance — Rated lifetime of 2000 hours at 105 °C with polarity inverted every 250 hours, meeting the UUN series endurance specification.
• Ripple Current Performance — Rated ripple current of 130 mA at 120 Hz and 260 mA at 10 kHz for a 47 µF device, with frequency coefficients defined in the series datasheet.
• Surface-Mount Chip Package — Chip-type radial can SMD package sized L: 1.35 × D: 1.25 cm with recommended solder land 1.28 × 1.28 cm for SMT assembly.
• Assembly Ready — Designed for automatic mounting machines and supplied for carrier-tape feed processing.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose Surface-Mount Circuits — Provides bi-polar capacitance in compact chip format for general electronic assemblies on high-density PCBs.
• Automated SMT Production — Tape-fed format and chip SMD package support high-volume automatic mounting workflows.
• Systems Requiring Wide Temperature Operation — Suitable for designs that need capacitor performance from −55 °C up to +105 °C.

Unique Advantages

• Bi‑polar operation: Enables use where polarity reversal or AC coupling is required within the specified endurance conditions.
• Compact chip SMD package: Delivers higher capacitance in a board-space-efficient form factor for high-density assemblies.
• Frequency-aware ripple handling: Specified ripple current values at 120 Hz and 10 kHz allow designers to evaluate performance across application frequencies.
• High-temperature endurance: 2000-hour rating at 105 °C (with polarity inversion per specification) supports longer-term reliability in elevated-temperature applications.
• SMT assembly compatibility: Tape-fed format and recommended land pattern dimensions simplify integration into automated production lines.
• RoHS compliant: Meets applicable RoHS directives for environmental and regulatory requirements.
