UUN1J470MNQ1MS

The UUN1J470MNQ1MS is a chip-type, bi-polarized aluminum electrolytic capacitor designed for surface mounting on high-density printed circuit boards. It delivers 47 µF at a 63 V rating with a compact SMD can-style package intended for general-purpose electronic designs.

Engineered for reliable performance across a wide temperature range, this RoHS-compliant part is suitable for automated assembly and applications that require stable capacitance and endurance under elevated temperature conditions.

Key Features

• Capacitance & Voltage — 47 µF rated capacitance with a 63 V voltage rating and ±20% tolerance at 120 Hz, 20 °C.
• Bi-polarized Construction — Designed as a bi-polarized series for operation over a wide temperature range of −55 °C to +105 °C.
• Endurance — Rated for 2000 hours at 105 °C; series endurance testing includes polarity inversion every 250 hours.
• Ripple Current — Specified ripple current: 140 mA at 120 Hz and 280 mA at 10 kHz, supporting common board-level ripple conditions.
• Leakage and Loss — Series leakage current specification: after 1 minute at rated voltage and 20 °C, leakage ≤ 0.03 C·V (µA); tangent of loss angle (tan δ) for 63 V is max. 0.10 at 120 Hz, 20 °C.
• Surface Mount Package — Chip-type radial can SMD package (L: 13.5 mm × D: 12.5 mm) with recommended land size L: 12.8 mm × W: 12.8 mm; compatible with carrier-tape automated mounting.
• Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Surface-mount, high-density PCBs — Compact chip form factor and SMD can package make the part suitable for tightly packed board layouts requiring electrolytic capacitance.
• General-purpose electronic designs — Provides bulk capacitance and ripple handling for a broad range of consumer and industrial circuits classified as general purpose.
• Automated assembly lines — Applicable to automatic mounting machines fed with carrier tape for efficient high-volume production.
