UUN0J222MNQ1MS

The UUN0J222MNQ1MS from Nichicon is a chip-type, bi‑polarized aluminum electrolytic capacitor designed for surface mounting on high-density printed circuit boards. It delivers a high capacitance value in a surface-mount radial can package for general-purpose electronic designs.

Engineered for wide temperature operation and automated assembly, this part supports demanding environmental ranges and manufacturing workflows while remaining RoHS compliant.

Key Features

• Capacitance & Voltage — 2.2 mF nominal capacitance at a rated voltage of 6.3 V with tolerance of −20% to +20%.
• Bi‑Polar Construction — Bi‑polarized design enables use in circuits that require non‑polar or polarity‑reversing operation across the stated temperature range.
• Wide Temperature Range — Rated for operation from −55 °C to +105 °C, supporting a broad set of environmental conditions.
• Surface Mount Package — Chip/radial can SMD package optimized for high-density PCB assembly; compatible with automated mounting machines fed by carrier tape.
• Endurance — Specified lifetime of 2000 hours at 105 °C with polarity inversion as part of the endurance test condition.
• Ripple Current Capability — Rated ripple current of 740 mA at 120 Hz and 851 mA at 10 kHz to support filtering and decoupling tasks across frequency ranges.
• Board Land Size — Recommended surface mount land size: 1.83 cm × 1.83 cm for PCB layout.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Leakage Current Specification — Series leakage guidance: after 1 minute application of rated voltage at 20 °C, leakage current not more than 0.03CV (µA), consistent with datasheet series criteria.

Typical Applications

• General-purpose surface-mount electronics — Provides high capacitance for bulk storage and decoupling on compact PCBs where SMD radial cans are required.
• Power filtering and decoupling — Supports power rail smoothing and transient handling with specified ripple current at both low and high frequencies.
• Circuits requiring bipolar capacitors — Suitable for designs that need non‑polar or polarity‑reversing capacitors within the stated temperature range.
• Automated assembly production — Designed for compatibility with carrier-tape fed pick-and-place processes for high-volume manufacturing.

Unique Advantages

• High capacitance in an SMD form — 2.2 mF nominal capacitance in a chip-type radial can lets designers consolidate bulk capacitance on space-constrained boards.
• Wide operating temperature — −55 °C to +105 °C rating enables use across demanding environmental conditions without derating design intent.
• Long endurance specification — 2000 hours at 105 °C provides a measurable reliability baseline for thermal stress in long‑life applications.
• Manufacturing‑friendly — Carrier-tape compatibility simplifies automated placement and throughput in production lines.
• Measured ripple performance — Quantified ripple current values at 120 Hz and 10 kHz help designers size capacitors for both mains-frequency and high-frequency filtering needs.
• RoHS compliant — Meets the stated environmental directive requirements for restricted substances.
