The TPME686M025R0055: This is a molded tantalum capacitor from the TPM series, rated 68 µF at 25 V with ±20% tolerance and a 55 mOhm ESR. The low ESR is the spec that matters most for a power rail — it keeps ripple voltage down and ripple current capability up. At 55 mOhm the self-heating from ripple current stays manageable, which is why this part shows up on post-regulator bulk stages and input filters for 3.3 V, 5 V, and even 12 V rails where the voltage margin is comfortable.
Full military temperature range — avionics and downhole ready
The molded case and surface-mount 2917 (7343 Metric) footprint mean it reflows on a standard profile and fits the same pad as other 7343 tantalums — no layout surprise.
