The TAJR335K010RNJ is a molded tantalum capacitor from the TAJ series, rated 3.3 µF at 10 V with ±10% tolerance. The 0805 case size (2.05 mm × 1.30 mm footprint) is a common chip size for automated assembly; pick-and-place equipment handles it without special nozzles, and the land pattern matches many standard tantalum capacitor footprints.
8 Ohm ESR — the limiting factor for ripple current and AC performance
With an equivalent series resistance of 8 Ohm, this capacitor's impedance at high frequency is dominated by the ESR, not the capacitance. The 8 Ohm ESR also limits the self-heating under ripple current.
The molded construction (Type: Molded) provides mechanical protection and moisture resistance across this range.
