UUN1A222MNQ1MS

The UUN1A222MNQ1MS is a chip‑type, bi‑polarized aluminum electrolytic capacitor designed for surface mounting on high‑density PCBs. It provides 2.2 mF capacitance at 10 V in a compact radial can SMD package and is intended for general‑purpose applications that require wide temperature operation and automated PCB assembly.

Key attributes include bi‑polar construction, RoHS compliance, operation from −55°C to +105°C, and a rated endurance of 2000 hours at 105°C, delivering stable performance in demanding thermal environments.

Key Features

• Bi‑Polar Construction Designed for bipolar operation to suit AC‑coupling and circuits requiring polarity reversal within the specified endurance test conditions.
• High Capacitance, Low Voltage 2.2 mF rated capacitance at 10 V for bulk decoupling and energy storage in compact, surface‑mount form.
• Wide Temperature Range Rated for operation from −55°C to +105°C to cover a broad set of environmental use cases.
• Endurance Specified lifetime of 2000 hours at 105°C with polarity inversion every 250 hours; capacitance change is within ±20% after the test (per datasheet series endurance specification).
• Ripple Current Capability Low‑frequency ripple current rating of 830 mA at 120 Hz and high‑frequency rating of 954.5 mA at 10 kHz, suitable for applications with significant ripple stress.
• Surface‑Mount Chip Package Radial can SMD package sized L: 2.15 × D: 1.8 cm with recommended land size L: 1.83 × W: 1.83 cm for automated placement.
• Assembly‑Friendly Applicable to automatic mounting machines and carrier‑tape fed processes for efficient high‑volume assembly.
• RoHS Compliant Conforms to RoHS directives (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• General‑Purpose Electronics Use where a compact, surface‑mount bi‑polar electrolytic capacitor (2.2 mF, 10 V) is required for bulk decoupling or energy buffering.
• High‑Density PCB Assemblies Suited to circuits with limited board area needing a high capacitance in a chip‑type SMD can that supports automated placement.
• Designs Requiring Wide Temperature Operation Appropriate for systems that must maintain capacitance and reliability across −55°C to +105°C environments.
• Automated Production Lines Carrier‑tape compatible for efficient pick‑and‑place operation in volume manufacturing.

Unique Advantages

• High Capacitance in a Compact SMD Can Enables significant bulk storage (2.2 mF at 10 V) without requiring through‑hole components, simplifying board layout.
• Bi‑Polar Operation Removes polarity constraints for AC‑coupled or polarity‑reversing circuits, increasing design flexibility.
• Robust Thermal Endurance 2000‑hour rating at 105°C with specified limits on capacitance change supports long‑term reliability in elevated temperatures.
• Measured Ripple Performance Rated ripple currents at 120 Hz and 10 kHz provide quantifiable margins for power filtering and decoupling design calculations.
• Assembly Efficiency Designed for carrier‑tape feeding and automatic placement to reduce PCB assembly time and handling cost.
• Regulatory Compliance RoHS compliance supports use in products that must meet restricted substance requirements.
