UUN1J470MNJ1MS

The UUN1J470MNJ1MS is a chip-type, bi-polarized aluminum electrolytic capacitor designed for surface mounting on high-density printed circuit boards. Its 47 µF capacitance and 63 V rated voltage provide mid-range energy storage for general-purpose SMD designs that require non-polarized capacitor solutions.

Built for broad temperature operation from −55 °C to +105 °C and compatible with automated carrier-tape mounting, this part addresses applications that need stable performance across wide environmental conditions and efficient assembly integration.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, suitable for general-purpose energy storage in non-polarized circuits.
• Bi-Polarized Construction — Bi-polarized design enables use where polarity is not fixed, supporting AC-coupling or bipolar signal paths.
• Surface Mount Chip Package — Chip-type radial can SMD package (L: 1.35 × D: 1.25 cm) optimized for high-density PCB layouts; surface-mount land size 1.28 × 1.28 cm.
• Wide Operating Temperature — Rated for −55 °C to +105 °C to maintain capacitance and performance across demanding temperature ranges.
• Endurance at Elevated Temperature — Qualified for 2000 hours at 105 °C with polarity inversion every 250 hours, providing predictable aging and reliability data for thermal stress conditions.
• Ripple Current Capability — Specified ripple current of 140 mA at 120 Hz and 280 mA at 10 kHz (series-level frequency coefficients apply), enabling AC ripple handling appropriate to its capacitance class.
• Manufacturing & Compliance — Applicable to automatic mounting machines fed with carrier tape and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose SMD circuits — Energy storage and decoupling on high-density surface-mount boards where a non-polarized capacitor is required.
• Bi-polar signal paths — Where polarity-independent operation is needed, the bi-polarized construction supports AC-coupling and bipolar circuits.
• Automated assembly environments — Designed for carrier-tape feeding to support high-volume surface-mount manufacturing processes.

Unique Advantages

• Bi-polarized flexibility: Eliminates polarity constraints for designs that handle AC or reversible-polarity signals.
• Wide temperature range: −55 °C to +105 °C rating supports designs that must operate reliably across harsh thermal conditions.
• Documented endurance: 2000 hours at 105 °C with defined test conditions gives clear expectations for life performance under elevated temperature stress.
• Assembly-ready package: Chip-type SMD footprint and carrier-tape compatibility streamline automated placement and reduce handling overhead.
• RoHS compliance: Meets 2011/65/EU and (EU)2015/863 requirements for restricted substances, simplifying regulatory acceptance in compliant products.
• Rated ripple handling: Specified ripple current values at both low and high frequencies align with the needs of SMD power and signal circuits in its capacitance class.
