UWT1H220MCL1GB

The UWT1H220MCL1GB is a chip‑type aluminum electrolytic capacitor designed for surface mounting on high‑density PC boards. It offers a 22 µF capacitance at a 50 V rating in a compact SMD radial-can package optimized for automated assembly.

Engineered for demanding temperature environments, this part operates from −55 °C to +105 °C, is RoHS compliant, and carries AEC‑Q200 qualification for applications requiring proven component reliability and endurance.

Key Features

• Electrical Rating — 22 µF capacitance, rated voltage 50 V with ±20% tolerance.
• Wide Temperature Range — Specified for operation from −55 °C to +105 °C to support systems exposed to wide thermal extremes.
• AEC‑Q200 Qualified — Qualified per AEC‑Q200 to meet automotive-grade reliability requirements.
• Surface Mount Chip Type — Designed for surface mounting on high‑density PC boards and compatible with carrier‑tape automated mounting.
• Compact Package — Case dimensions L: 5.4 × D: 8 mm; surface mount land size L: 8.3 × W: 8.3 mm; radial can SMD construction with black top marking.
• Endurance — Rated for 1000 hours at 105 °C with the rated voltage applied; for 25 V and higher parts capacitance change remains within ±20% after test.
• Low Leakage and Loss — Leakage current after 2 minutes at 20 °C: ≤ 0.01CV or 3 μA (whichever is greater). Tan δ (120 Hz, 20 °C) for 50 V: max 0.14.
• Ripple Current — 51 mA at 120 Hz and 76.5 mA at 10 kHz, suitable for typical decoupling and filtering tasks in compact assemblies.

Typical Applications

• Automotive electronics — For electronic modules and control units that require AEC‑Q200 qualified capacitors across a wide temperature range.
• High‑density PCB assemblies — Chip package and carrier‑tape compatibility simplify placement in space constrained boards assembled with automated pick‑and‑place.
• RoHS‑compliant designs — Fits designs that require environmental compliance under the RoHS directive.

Unique Advantages

• Wide operating temperature capability — −55 °C to +105 °C rating supports use in harsh thermal environments without derating design targets.
• Automated assembly ready — Carrier‑tape compatibility and surface‑mount format reduce manual handling and speed production throughput.
• Automotive‑grade reliability — AEC‑Q200 qualification provides documented reliability for demanding system requirements.
• Proven endurance — 1000 hours at 105 °C with rated voltage applied gives predictable long‑term behavior for high‑temperature applications.
• Controlled electrical performance — Specified tan δ, low leakage current, and published ripple current figures allow straightforward thermal and circuit design calculations.
• Compact footprint — Small L: 5.4 × D: 8 mm package and defined land pattern (8.3 × 8.3 mm) enable dense BOM implementations.
