UUJ1J221MNJ6MS

The UUJ1J221MNJ6MS is a chip-type aluminum electrolytic capacitor intended for surface mounting on high-density PC boards. It delivers 220 µF capacitance at a 63 V rating in a compact radial can SMD package designed for automatic mounting with carrier tape.

Designed for demanding environments, this part is AEC-Q200 qualified, RoHS compliant, and specified for operation from -55 °C to 105 °C with a published 5000-hour lifetime at 105 °C.

Key Features

• Electrical Performance — 220 µF capacitance at 63 V with a tolerance of -20% to +20% and polarized construction for DC applications.
• Thermal and Lifetime — Rated for an operating temperature range of -55 °C to 105 °C and specified for 5000 hours at 105 °C.
• Ripple Current Capability — Ripple current ratings of 385 mA at 120 Hz and 577.5 mA at 10 kHz for AC and switching applications within specified limits.
• Package and Mounting — Chip-type radial can SMD in a 2.1 × 1.25 cm footprint (L × D) with a recommended land size of 1.28 × 1.28 cm; compatible with automatic mounting machines fed with carrier tape.
• Reliability and Standards — AEC-Q200 qualified and RoHS (2011/65/EU, (EU)2015/863) compliant for regulated applications.
• Series Capability — Part of the UUJ series offering higher capacitance in larger chip case sizes (φ12.5, φ16, φ18) for designs requiring elevated energy storage in SMD format.

Typical Applications

• Automotive power electronics — Suitable for power smoothing and decoupling in automotive systems, supported by AEC-Q200 qualification and 105 °C endurance data.
• DC–DC converters and power rails — 220 µF at 63 V and rated ripple currents make this capacitor appropriate for bulk capacitance and transient handling on intermediate rails.
• Embedded and industrial control — Surface-mount chip form factor and carrier-tape compatibility simplify assembly for compact, high-density control boards.

Unique Advantages

• AEC-Q200 Qualified: Provides a documented reliability baseline for use in regulated and demanding environments.
• High-temperature endurance: 5000 hours at 105 °C supports long-term stability under elevated thermal stress.
• Compact SMD can package: Delivers relatively large capacitance in a chip-type radial can SMD footprint for space-constrained layouts.
• Carrier-tape compatible: Designed for automatic mounting, reducing manual handling and easing high-volume assembly.
• Measured ripple ratings: Published ripple current values at both 120 Hz and 10 kHz allow designers to size capacitors using application-specific AC stress data.
• Regulatory compliance: RoHS compliance supports use in designs requiring restricted-substance adherence.
