UUN0J222MNJ1MS

The UUN0J222MNJ1MS from Nichicon is a chip-type, bi-polarized aluminum electrolytic capacitor designed for surface-mount assembly on high-density printed circuit boards. It delivers 2.2 mF of capacitance at a 6.3 V rating in a compact SMD can package, with a broad operating temperature range of −55 °C to +105 °C.

Targeted for general-purpose electronics, the part supports automated placement (carrier-tape compatible) and offers endurance and ripple-current characteristics suitable for designs that require higher capacitance in a surface-mount form factor.

Key Features

• Capacitance & Voltage — 2.2 mF capacitance rated at 6.3 V with a tolerance of −20% to +20% for predictable bulk-energy storage in board-level designs.
• Bi-polarized Construction — Bi-polarized design supports applications where polarity reversal may occur; explicit polarization is not required.
• Wide Temperature Range — Specified for operation from −55 °C to +105 °C, enabling use across a wide range of thermal environments.
• Surface-Mount Package — Chip-style radial can SMD package sized L: 1.65 × D: 1.8 cm with a recommended land pattern of 1.83 × 1.83 cm; compatible with automatic mounting machines fed with carrier tape.
• Endurance — Qualified for 2000 hours at 105 °C with polarity inversion every 250 hours; after this test the capacitance change is within ±20%, tan δ is ≤200% of initial specified value, and leakage current remains at or below initial specified levels.
• Ripple Current Performance — Rated ripple current of 740 mA at 120 Hz and 851 mA at 10 kHz to support AC stress conditions within the specified frequency bands.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Electronics — Suited for general-purpose circuit designs requiring a 2.2 mF, 6.3 V bi-polarized surface-mount capacitor within a −55 °C to +105 °C temperature range.
• Surface-Mount Assembly Processes — Designed for high-density PC boards and compatible with automatic mounting machines fed by carrier tape to streamline PCB assembly.
• High-Temperature Operation — Intended for use where sustained performance at elevated temperatures is required, supported by a 2000-hour endurance rating at 105 °C with polarity inversion testing.

Unique Advantages

• High Capacitance in a Chip Package: 2.2 mF capacitance in a compact SMD can delivers substantial bulk capacitance without a large through-hole footprint.
• Bi-Polarized Flexibility: Bi-polar construction removes the need for strict polarity orientation in applications that may experience polarity reversal.
• Designed for Automated Assembly: Carrier-tape compatibility and surface-mount format reduce manual handling and speed production on automated pick-and-place lines.
• Robust Thermal Endurance: 2000-hour rated life at 105 °C with defined post-test limits ensures predictable aging and stability in elevated-temperature deployments.
• Measured Ripple Capability: Specified ripple current values at 120 Hz and 10 kHz provide quantifiable behavior under AC stress for design verification.
• Regulatory Compliance: RoHS compliance supports use in designs requiring adherence to current restricted-substance directives.
