UUN0J222MNQ6MS

The UUN0J222MNQ6MS is a chip‑type, bi‑polar aluminum electrolytic capacitor optimized for surface mounting on high‑density PC boards. It provides a high capacitance of 2.2 mF at a rated voltage of 6.3 V for general purpose electronic applications that require bipolar operation across a wide temperature range.

Designed for automated assembly and long‑life operation, this SMD radial can delivers robust capacitance stability and ripple handling for circuits that need reliable AC or polarity‑inverting performance in compact layouts.

Key Features

• Capacitance & Voltage — 2.2 mF nominal capacitance with a rated voltage of 6.3 V and tolerance of ±20% for bulk energy storage and decoupling in polarity‑reversing circuits.
• Bi‑polarized Construction — Built for bipolar operation; endurance testing specified with polarity inversion provides suitability for circuits where voltage polarity can change.
• Wide Operating Temperature — Specified operating range of −55°C to +105°C to support use across demanding thermal environments.
• Endurance & Reliability — Lifetime rating of 2000 hours at 105°C (with polarity inversion per endurance test conditions) and capacitance change within ±20% after endurance testing.
• Ripple Performance — Rated ripple current of 740 mA at 120 Hz and 851 mA at 10 kHz to handle AC components and switching noise in power and signal circuits.
• Surface Mount Chip Package — Radial can SMD chip type designed for high‑density PCBs and compatible with carrier‑tape automated mounting.
• Board Land Footprint — Recommended surface mount land size: 1.63 × 1.63 cm for reliable placement and solder joints.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General purpose electronics — Bulk decoupling and energy storage where a bipolar electrolytic capacitor is required on a compact PCB layout.
• Circuits requiring bipolar operation — AC‑coupling and signal circuits or designs where polarity can reverse during operation.
• High‑density PCB assemblies — Surface‑mount radial can form factor suited for automated assembly on tightly packed boards.

Unique Advantages

• High capacitance in an SMD chip — 2.2 mF nominal capacitance provides significant bulk storage while remaining compatible with surface‑mount assembly and compact board designs.
• Bipolar capability for flexible circuit design — Eliminates the need for polarity‑specific capacitors in applications with reversing voltages, simplifying BOM and layout choices.
• Wide temperature range — −55°C to +105°C rating supports operation in varied thermal environments without specification changes.
• Engineered for automated production — Carrier‑tape compatibility and SMD packaging streamline pick‑and‑place and reflow workflows for volume manufacturing.
• Measured ripple handling — Specified ripple current values at 120 Hz and 10 kHz give clear guidance for AC and switching noise mitigation in power and signal domains.
• RoHS compliant — Conforms to current RoHS requirements for environmental and regulatory conformity.
