UUN1H471MNJ6MS

The UUN1H471MNJ6MS from Nichicon is a chip-type, bi-polarized aluminum electrolytic capacitor optimized for surface-mount applications on high-density printed circuit boards. It delivers a higher capacitance option in an SMD can-style package while maintaining compatibility with automated assembly.

Designed for general-purpose use, this 470 µF, 50 V capacitor supports wide temperature operation from −55 °C to +105 °C and is RoHS compliant, making it suitable for electronics that require robust capacitance in demanding thermal environments.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 50 V for higher energy storage in a compact SMD package.
• Bi-Polarized Construction — Bi-polarized design for applications that require polarity flexibility; series is specified as bi-polarized.
• Wide Operating Temperature — Rated for −55 °C to +105 °C to support designs exposed to broad thermal ranges.
• Endurance & Reliability — Life tested to 2000 hours at 105 °C (with polarity inversion in endurance testing) to demonstrate long-term stability under high-temperature stress.
• Ripple Current Performance — Specified ripple currents of 640 mA at 120 Hz and 960 mA at 10 kHz to support AC ripple and decoupling demands across frequencies.
• Surface-Mount, Can-Style Package — Radial can SMD package designed for surface mounting on high-density PCBs; size L: 2.15 × D: 1.8 cm with recommended land size L: 1.83 × W: 1.83 cm.
• Assembly Compatibility — Applicable to automatic mounting machines fed with carrier tape for efficient, automated PCB assembly.
• RoHS Compliant — Manufactured in compliance with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Power Conditioning — Provides bulk capacitance on surface-mount PCBs for smoothing and decoupling in general-purpose electronic equipment.
• High-Density PCB Designs — SMD can package fits automated assembly flows and saves board area in compact or densely populated layouts.
• Temperature-Variable Environments — Suited for equipment that must operate reliably across −55 °C to +105 °C.

Unique Advantages

• High Capacitance in SMD Can — 470 µF available in a chip-type radial can lets designers achieve larger capacitance without reverting to through-hole parts.
• Bi-Polarized Flexibility — Bi-polar construction supports applications where polarity can change, as reflected in the series design and endurance testing.
• Frequency-Responsive Ripple Handling — Specified ripple current ratings at both 120 Hz (640 mA) and 10 kHz (960 mA) provide predictable behavior across common ripple frequency ranges.
• Automated Assembly Ready — Compatible with carrier-tape fed automatic mounting, simplifying high-volume PCB assembly workflows.
• Designed for Harsh Thermal Conditions — Rated to operate from −55 °C to +105 °C with a 2000-hour endurance at 105 °C, supporting long-term performance in elevated temperature applications.
• Regulatory Compliance — RoHS compliance supports regulatory requirements for restricted substances.
