UUN1A471MNJ1MS

The UUN1A471MNJ1MS is a chip-type, bi-polarized aluminum electrolytic capacitor designed for surface mounting on high-density PC boards. With a 470 µF capacitance at a 10 V rating and a compact radial can SMD package, it targets general-purpose electronic circuits that require higher capacitance in a small footprint.

This component offers wide temperature operation from −55 °C to +105 °C and is RoHS compliant, providing a reliable option for designs that need bidirectional polarity handling and frequency-dependent ripple performance.

Key Features

• Capacitance & Voltage — 470 µF capacitance at a 10 V rated voltage with a tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Bi-Polar Construction — Bi-polarized design suitable for circuits requiring no fixed polarity, supporting alternating or inverted voltage conditions as specified for the series.
• Wide Temperature Range — Rated for operation from −55 °C to +105 °C, enabling use across a broad set of environmental conditions.
• Surface-Mount Chip Package — Radial can SMD package sized L: 1.35 × D: 1.25 cm with a recommended land size of 1.28 × 1.28 cm for high-density PCB assembly and automatic mounting.
• Ripple Current Performance — Rated ripple current of 340 mA at 120 Hz and 510 mA at 10 kHz, supporting both low- and high-frequency ripple handling in power and signal circuits.
• Endurance & Reliability — Specified lifetime of 2000 hours at 105 °C with polarity inversion every 250 hours, with post-test limits for capacitance, tan δ and leakage current defined by the series endurance specification.
• RoHS Compliance — Manufactured in compliance with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Power Filtering — Acts as a bulk decoupling or smoothing capacitor in circuits where a bi-polarized capacitor and higher capacitance are required.
• AC-Coupled Circuits — Suitable for circuits that experience polarity inversion or alternating voltages due to its bi-polarized construction and defined endurance under inverted polarity.
• Compact, High-Density PCB Designs — Designed for automatic surface-mount assembly and tight board layouts where higher capacitance must fit within a small radial-can SMD footprint.

Unique Advantages

• High Capacitance in a Compact SMD Can — 470 µF in a chip-type radial can SMD allows designers to achieve higher energy storage without increasing board area significantly.
• Bi-Polar Operation — Eliminates polarity constraints in applications that encounter alternating or inverted voltages, reducing the need for polarity-specific design workarounds.
• Wide Thermal Operating Window — −55 °C to +105 °C capability supports use across diverse environmental conditions and thermal profiles.
• Frequency-Responsive Ripple Handling — Specified ripple current at 120 Hz and 10 kHz (340 mA and 510 mA respectively) gives predictable performance for both low- and higher-frequency ripple environments.
• Endurance-Defined Reliability — 2000 hours at 105 °C with polarity inversion intervals provides a measurable reliability baseline for high-temperature applications.
• RoHS-Compliant Manufacture — Conforms to current RoHS requirements for material and environmental compliance.
