Capacitance and voltage — the BOM-fit numbers
The TAJC335K035TNJ is a 3.3 µF tantalum capacitor rated at 35 V. That voltage rating gives you headroom on a 24 V rail or a 12 V bus with margin for transients — the 35 V ceiling means it survives a 24 V system's load-dump spike without derating anxiety.
Package and polarity — board-fit checklist
Supplied in Tape & Reel packaging, the TAJC335K035TNJ is a surface-mount tantalum chip. Tantalum caps are polarised — the anode band on the body marks the positive terminal, and the cathode is the larger pad side. Reversing the polarity on a tantalum cap can cause a short and a fire risk, so the orientation mark is the one thing to get right before the reflow oven.
RoHS compliance — regulatory gate cleared
The TAJC335K035TNJ is RoHS compliant, which means it meets the EU Restriction of Hazardous Substances directive for lead, mercury, cadmium, and other restricted materials. No exemption paperwork needed for a standard commercial or industrial design.
