Product details

2.2 µF at 10 V — what the ratings mean on your board

The TAJA225K010RNJV: This is a 2.2 µF tantalum capacitor rated for 10 V DC, in a standard 1206 (3216 metric) molded case. The 7 Ohm ESR at 100 kHz tells you it will self-heat under ripple current — in a switching regulator output, keep the RMS ripple below about 100 mA to stay within the 2000-hour lifetime at 125°C.

Temperature range and lifetime — where it survives

That makes it suitable for outdoor telecom gear, engine-bay electronics, or any environment where the board sees sustained heat. The full mil-temp range also covers avionics and downhole equipment.

Frequently asked questions

Can TAJA225K010RNJV be replaced by a ceramic capacitor?

A 2.2 µF 10 V X7R ceramic in 1206 is a functional replacement for many decoupling applications, but ceramics have different DC bias characteristics and no wear-out mechanism. Tantalum offers stable capacitance over voltage and a known failure mode (short) vs ceramic's piezoelectric noise. Test the substitution for your specific circuit.
