6.8 µF, 16 V, 1.5 Ohm ESR — bulk decoupling fit
Rated 6.8 µF at 16 V with ±10% tolerance, this molded tantalum capacitor is a common choice for bulk decoupling on 3.3 V or 5 V rails where the 16 V rating provides derating margin. The 1.5 Ohm ESR is moderate for a 1206-size tantalum — it limits ripple current to roughly 300 mA RMS before self-heating becomes a concern, so it suits low-ripple DC rails rather than high-frequency switching supplies. The 1206 (3216 metric) case is a standard footprint, compatible with automated pick-and-place assembly.
RoHS compliance and ordering
The part is listed as RoHS compliant, meeting the restriction on hazardous substances for EU and global markets.
