The ±10% tolerance keeps the actual capacitance within 29.7 µF to 36.3 µF over the production spread. ## 900 mOhm ESR and the ripple-current ceiling The 900 mOhm ESR at 25°C sets the self-heating under ripple current: a 100 kHz switching regulator with 500 mA ripple current dissipates about 225 mW in the capacitor, which raises the internal temperature by roughly 10-15°C above ambient. Budget this rise when operating near the 125°C upper limit. The TAJ series is a standard molded-tantalum line from KYOCERA AVX, and this case size C (2312 metric) is a common footprint.","metaTitle":"TAJC336K025RNJ KYOCERA AVX 33 µF 25 V Molded Tantalum","metaDescription":"TAJC336K025RNJ: 33 µF, 25 V, ±10% tolerance, 900 mOhm ESR, -55°C to 125°C.
