10 µF, 16 V, 500 mOhm ESR — molded tantalum for tight boards
The TPSB106K016R0500: This is a 10 µF molded tantalum capacitor rated at 16 V with a 500 mOhm ESR, housed in the compact 1411 (3528 Metric) / 1210 case — size code B. The molded construction gives consistent dimensions and a flat top for pick-and-place, and the ±10% tolerance covers most decoupling and bulk storage needs without overspecifying. The 500 mOhm ESR is the key thermal parameter: it limits ripple current handling.
That means it can sit in an avionics black box cycling between a cold-soaked -55°C and a hot engine bay at 125°C, or in a downhole tool where ambient exceeds 105°C. The molded case and tantalum dielectric hold capacitance and ESR across that swing better than electrolytics.
