15 µF, 6.3 V, 0805 — BOM fit for this tantalum
The TAJR156K006RNJ is a molded tantalum capacitor from KYOCERA AVX's TAJ series, rated at 15 µF capacitance with ±10% tolerance and a 6.3 V DC voltage rating. The 0805 case size (2.05 mm x 1.30 mm footprint, 1.20 mm seated height) is a common PCB footprint, making it a drop-in candidate for many low-voltage decoupling or bulk storage positions.
In a 6.3 V rail, this part can handle moderate ripple; for higher ripple applications, a lower-ESR tantalum or polymer capacitor would be needed.
