The TPSB686K006R0250 is a 68 µF molded tantalum capacitor rated at 6.3 V, ±10% tolerance — a common decoupling value for low-voltage digital supply rails where voltage derating keeps the failure rate negligible. With a 250 mOhm ESR, this cap can handle a few hundred mA of ripple current before self-heating becomes a concern; the ESR also sets the output ripple amplitude in a buck converter's output filter.
Package and footprint — two case sizes in one order code
Listed as 1411 (3528 Metric) / 1210, this cap fits either pad layout — the 3.50 mm x 2.80 mm footprint with a seated height of 2.10 mm means it drops into a standard 1210 land pattern without a board spin.
