The TAJB107K010RNJ is a 100 µF ±10% molded tantalum capacitor rated at 10 V DC, built in the industry-standard B case size (1411 / 3528 Metric). With an ESR of 1.4 Ohm at 100 kHz, this capacitor handles moderate ripple currents typical of linear regulators and low-frequency switching converters, but the ESR limits its use in high-frequency, high-ripple designs where a low-ESR polymer or ceramic would be a better fit.
This makes it suitable for avionics, satellite, downhole drilling, and other applications where the ambient temperature exceeds the industrial 85°C limit.
