UWT1A220MCL1GB

The UWT1A220MCL1GB is a chip-type aluminum electrolytic capacitor from Nichicon's UWT series. It delivers 22 µF at 10 V in a compact surface-mount radial can package designed for high-density PC boards and automated assembly.

Engineered for wide temperature operation and long-term endurance, this part is RoHS compliant and AEC-Q200 qualified, making it suitable for demanding environments and automotive-class designs that require stable performance across -55°C to +105°C.

Key Features

• Capacitance & Voltage: 22 µF rated capacitance at 10 V with a tolerance of ±20% (120 Hz, 20°C).
• Wide Operating Temperature: Rated for -55°C to +105°C to support a broad range of environmental conditions.
• Endurance: Specified lifetime of 1000 hours at 105°C with defined limits for capacitance change, tan δ and leakage current after the endurance test.
• Package & Mounting: Chip-type radial can SMD, dimension L: 5.4 × D: 5 mm; surface-mount land size L: 5.3 × W: 5.3 mm; compatible with automatic mounting machines fed with carrier tape.
• Electrical Characteristics: Polarized capacitor with leakage current specified as not more than 0.01CV or 3 µA (whichever is greater) after 2 minutes at 20°C; tan δ max 0.24 at 10 V, 120 Hz.
• Ripple Current: 27 mA at 120 Hz and 40.5 mA at 10 kHz for filtering and decoupling applications.
• Compliance & Qualification: RoHS directive compliant and AEC-Q200 qualified.

Typical Applications

• Automotive electronics — AEC-Q200 qualification and wide temperature range make this part suitable for automotive modules and systems requiring robust capacitors.
• High-density PCB assemblies — Chip-type surface-mount can fits compact layouts where board space is constrained.
• Automated production — Carrier-tape compatibility enables efficient pick-and-place assembly in high-volume manufacturing.

Unique Advantages

• Wide environmental range: Operation from -55°C to +105°C enables use across thermal extremes without changing capacitor selection.
• Automotive-grade qualification: AEC-Q200 status provides a defined qualification baseline for automotive applications.
• Compact SMD can form factor: Small L × D footprint (5.4 × 5 mm) and matched land pattern optimize board area and simplify layout.
• Defined high-temperature endurance: 1000 hours at 105°C endurance rating supports long-term stability in hot operating conditions.
• Manufacturing-ready packaging: Designed for carrier-tape feeding to streamline automated assembly and reduce handling complexity.
• Predictable electrical behavior: Specified leakage current, tan δ, and ripple current figures provide measurable parameters for design margin calculations.
