35 V rated, 1 µF, 0805 — fit for bypass and coupling
The TAJP105K035RNJ: This is a KYOCERA AVX TAJ series molded tantalum capacitor, 1 µF ±10% tolerance, rated 35 V DC in the compact 0805 (2012 Metric) case size. The 35 V rating gives headroom on a 24 V bus or 12 V rail, keeping the derating margin recommended for solid tantalum capacitors. The 11 Ohm ESR is typical for a small-case tantalum at this capacitance and voltage. That ESR limits ripple current handling — for a bypass cap on a low-noise analog rail or a coupling cap in audio, it is acceptable; for a high-ripple switching supply output, a lower-ESR polymer or MLCC would be a better fit.
The TAJ series is a broad molded tantalum family; if the 0805 case or 35 V rating is not available in your volume window, other TAJ size codes or voltage variants may be cross-shopped. No pin-compatible direct second source is listed.
Polarity and mounting — surface-mount 0805
This is a polarized tantalum capacitor. The anode (+) is marked on the body; reverse voltage or AC bias will damage the part. Mounting is standard 0805 reflow soldering — the 2.05 mm x 1.35 mm footprint with 1.50 mm seated height fits tight PCB layouts.
