10 µF at 16 V — the common decoupling BOM position
The TAJB106M016K: 10 µF at 16 V in a 1210 molded case — this is the staple tantalum value for 3.3 V and 5 V rail decoupling in industrial and telecom boards. The ±20% tolerance covers the full temperature range without a voltage-coefficient surprise. Molded construction with a 2.8 Ohm ESR at 16 V means the ripple current rating is about 180 mA RMS at 85 °C — enough for output filtering on a low-power LDO or a POL converter, but tight for a high-ripple SMPS output.
The tantalum dielectric holds capacitance across that span with no derating needed at the low end. At 125 °C the voltage derating follows the standard tantalum curve — 16 V rated means a recommended applied voltage of 10 V or less for best reliability in high-temperature continuous service.
