The TAJB106M020RNJ: Rated 10 µF at 20 V with a ±20% tolerance, this Molded tantalum capacitor delivers 2.1 Ohm ESR in the compact B case (1411/3528 Metric). The 2.1 Ohm ESR limits ripple heating in a 100 kHz buck output filter — keep the RMS ripple current below the capacitor's thermal rating to stay within the 125°C ceiling.
The 20 V rating provides headroom for a 12 V rail with 50% derating per MIL-PRF-55365 guidelines.
