UUN1C471MNQ1MS

The UUN1C471MNQ1MS is a chip‑type, bi‑polarized aluminum electrolytic capacitor in the Nichicon UUN series designed for surface mounting on high‑density PC boards. It delivers a high capacitance value (470 µF) at a 16 V rating in an SMD radial can package suited for automated assembly.

Engineered for general‑purpose applications that require stable performance across a wide temperature range, this part supports operation from −55 °C to +105 °C, includes RoHS compliance, and offers long endurance under elevated temperature stress.

Key Features

• Electrical performance — 470 µF rated capacitance with ±20% tolerance and 16 V rated voltage; bi‑polarized design for AC or inverted‑polarity operation.
• Wide temperature range — Specified for operation from −55 °C to +105 °C to support designs exposed to broad ambient conditions.
• Endurance & reliability — Endurance rating of 2000 hours at 105 °C with polarity inversion every 250 hours; leakage current limit defined as I ≤ 0.03CV (µA) after 1 minute at 20 °C.
• Ripple handling & frequency response — Rated ripple current of 420 mA at 120 Hz and 630 mA at 10 kHz; frequency coefficient for 100–470 µF: 50 Hz = 0.80, 120 Hz = 1.00, 300 Hz = 1.23, 1 kHz = 1.34, ≥10 kHz = 1.50.
• Compact SMD radial can package — Physical dimensions L: 1.65 × D: 1.6 cm with recommended land size L: 1.63 × W: 1.63 cm; black top marking for easy identification.
• Assembly friendly — Chip type designed for surface mounting on high‑density PC boards and compatible with automatic mounting machines fed with carrier tape.
• Low‑temperature stability — Impedance ratios for 16 V rating: Z(−25 °C)/Z(+20 °C) = 3 and Z(−40 °C)/Z(+20 °C) = 6, per series specification.

Typical Applications

• General‑purpose electronic assemblies — Use where a high capacitance, bi‑polarized SMD electrolytic is required and operation across −55 °C to +105 °C is necessary.
• Power filtering and decoupling — Suitable for smoothing and decoupling duties in compact boards that require surface‑mount radial can capacitors with higher capacitance values.
• High‑density PC boards — Designed specifically for mounting on densely populated boards and compatible with automated carrier‑tape placement.

Unique Advantages

• High capacitance in SMD form factor — 470 µF in a chip‑type radial can provides needed capacitance without a bulky through‑hole footprint.
• Bi‑polarized operation — Enables use in AC‑coupled or polarity‑inverted circuits where non‑polar behavior is required.
• Wide ambient tolerance — Rated −55 °C to +105 °C to support a broad range of environmental conditions.
• Defined ripple and frequency behavior — Published ripple current values and frequency coefficients let designers predict performance across common frequencies.
• Manufacturing friendly — Carrier‑tape compatiblity and SMD package simplify automated placement on high‑density assemblies.
• Datasheet‑specified endurance — 2000 hours at 105 °C with polarity inversion and defined leakage/tan δ limits provide clear reliability expectations.
