Product details

What this 0.47 µF 50 V tantalum capacitor is for

The TAJS474K050RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 0.47 µF with a 50 V working voltage and ±10% tolerance.

ESR and its effect on circuit design

The 9.5 Ohm ESR at 100 kHz is a mid-range value for a 0.47 µF tantalum in this package — it sets the ripple current capability and self-heating under AC load. For decoupling a 50 V rail where ripple is under 100 mA, the ESR is acceptable; for high-ripple switching supplies, the power dissipation (I² × ESR) may push the part above its rated temperature if not derated.

Frequently asked questions

How can I order TAJS474K050RNJ or check current pricing?

Submit an RFQ for TAJS474K050RNJ with your target quantity. The part is Active, so no last-time-buy constraints apply.

Is TAJS474K050RNJ polarized?

Yes, as a tantalum capacitor it is polarized. The positive terminal is marked on the molded body. Reversing the voltage can cause catastrophic failure — observe the polarity marking during placement.
