UWT1A221MCL1GS

The UWT1A221MCL1GS is a chip-type aluminum electrolytic capacitor specified at 220 µF and 10 V, designed for surface mounting on high-density PC boards. It features a compact radial can SMD package (L: 7.7 × D: 6.3 mm) and a surface-mount land footprint of 6.6 × 6.6 mm.

Engineered for demanding environments, this part operates across a wide temperature range (−55 °C to +105 °C), is RoHS compliant, and is AEC-Q200 qualified, making it suitable for automotive electronics assemblies and automated mounting processes.

Key Features

• Electrical Performance — 220 µF nominal capacitance at 10 V with ±20% tolerance, polarized design suitable where high capacitance in a small SMD package is required.
• Wide Temperature Range — Specified operation from −55 °C to +105 °C to support designs exposed to broad thermal conditions.
• Endurance and Reliability — Rated for 1000 hours at 105 °C with defined limits for capacitance change, tan δ, and leakage current after the endurance test.
• Ripple Current Ratings — Ripple current handling specified as 105 mA at 120 Hz and 157.5 mA at 10 kHz, enabling predictable AC performance in the intended frequency bands.
• Package & Mounting — Chip-type radial can SMD package designed for high-density PCBs; compatible with automatic mounting machines fed with carrier tape.
• Compliance & Qualification — RoHS directive compliance and AEC-Q200 qualification documented in the product data.

Typical Applications

• Automotive electronic modules — Intended for use in automotive electronic assemblies that require qualified SMD aluminum electrolytic capacitance across a wide temperature range.
• High-density PC boards — Suited to compact board layouts where a small SMD can footprint and surface-mount land pattern are required.
• Automated assembly environments — Designed for compatibility with automatic mounting machines using carrier tape for efficient production.

Unique Advantages

• Wide operating temperature capability — −55 °C to +105 °C rating supports designs exposed to extreme ambient conditions.
• AEC-Q200 qualification — Provides a documented qualification path for use in automotive electronics applications.
• Compact SMD can form factor — Small footprint (L: 7.7 × D: 6.3 mm) and defined land size (6.6 × 6.6 mm) enable space-efficient board designs.
• High-temperature endurance — Specified 1000-hour life at 105 °C gives predictable long-term performance at elevated temperatures.
• Predictable ripple handling — Specified ripple current values at 120 Hz and 10 kHz help designers evaluate thermal and AC performance.
• Manufacturing-friendly — Carrier-tape feed compatibility streamlines pick-and-place assembly on automated lines.
