UUN1H470MNQ1MS

The UUN1H470MNQ1MS is a bi‑polar aluminum electrolytic chip capacitor in an SMD radial can package, optimized for surface mounting on high‑density PC boards. It delivers 47 µF capacitance at a 50 V rating with bi‑polar construction for AC or polarity‑reversing applications across a broad temperature range.

Designed for general‑purpose use, this RoHS‑compliant capacitor targets applications that require stable capacitance, elevated operating temperature capability, and reliable ripple handling in compact surface‑mount assemblies.

Key Features

• Capacitance & Voltage — 47 µF rated capacitance at 50 V provides mid‑range energy storage for decoupling and filtering in compact circuits.
• Bi‑Polar Construction — Bi‑polarized design enables operation with polarity reversal and AC coupling applications over -55 °C to +105 °C.
• Temperature & Endurance — Rated for continuous operation from -55 °C to +105 °C with an endurance specification of 2000 hours at 105 °C.
• Ripple Handling — Frequency‑dependent ripple current capability with 130 mA at 120 Hz and 260 mA at 10 kHz helps manage AC stress in power and signal paths.
• Surface‑Mount Chip Type — Chip‑type radial can SMD package is made for high‑density PCBs and is compatible with automated mounting using carrier tape.
• Tolerance & Reliability — Capacitance tolerance ±20% and leakage current limits defined by series specifications support predictable, repeatable performance.
• Package & PCB Land Pattern — Part dimensions L: 13.5 mm × D: 12.5 mm with recommended surface mount land size of 12.8 mm × 12.8 mm for PCB layout and assembly.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC coupling and bipolar signal circuits — Bi‑polar topology supports circuits that require capacitance under polarity reversals or AC biasing.
• Power rail decoupling on compact PCBs — SMD radial can form factor and recommended land pattern make it suitable for high‑density board layouts where stable mid‑range capacitance is needed.
• Industrial and control electronics — Wide operating temperature range (-55 °C to +105 °C) and extended endurance support designs exposed to temperature extremes.
• General‑purpose filtering — Ripple current ratings at 120 Hz and 10 kHz help suppress AC ripple in power supplies and conditioning stages.

Unique Advantages

• Bi‑polar capability for AC operation: Enables use in circuits with polarity reversals or AC coupling without polarity constraints.
• Compact SMD chip form factor: Supports automated placement and efficient use of board area on high‑density PCBs.
