The TPSA226K006R0300 is a molded tantalum capacitor from the TPS series, offering 22 µF capacitance with ±10% tolerance at a rated voltage of 6.3 V. This part is a standard choice for bulk decoupling on 3.3 V and 5 V power rails in industrial and telecom equipment, where the 6.3 V rating provides adequate derating margin for 5 V rails (typically derated to 80% of rated voltage per tantalum application guidelines).
300 mOhm ESR and 2000-hour endurance at 125°C
With an ESR of 300 mOhm at 100 kHz, this capacitor handles ripple current with moderate self-heating — suitable for output filtering in low-power DC-DC converters and POL regulators.
The 1206 (3216 Metric) case size is widely stocked across the supply chain, so lead times are typically short for active parts in this package.
