The TAJR334K020RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 0.33 µF with a 20 V working voltage and ±10% tolerance. The 0805 (2012 Metric) case size and 25 Ohm ESR make it a fit for general-purpose decoupling and filtering on boards where tantalum's stable capacitance over voltage bias is preferred over X5R/X7R ceramics.
The evidence does not list a RoHS compliance statement. Confirm with the datasheet or request a certificate of compliance at quote time.
A 0.33 µF 20 V X7R or X5R ceramic in 0805 is a functional alternative for decoupling, but the tantalum's ESR (25 Ohm) and DC bias stability differ. Ceramics lose capacitance under DC bias; tantalum does not. Verify the ripple current and ESR requirements of your node before substituting.
