680 µF, 23 mOhm ESR — bulk decoupling anchor
The TPMV687K006R0023 is a molded tantalum capacitor from KYOCERA AVX's TPM series, rated at 680 µF and 6.3 V with a low 23 mOhm ESR. At this capacitance and ESR, the cap can handle several amps of ripple without self-heating past the 125 °C ceiling.
Molded 2924 case — footprint and reflow
The 2924 (7361 Metric) case measures 7.30 mm x 6.10 mm with a seated height of 3.75 mm. It is a standard large-case tantalum — the pad layout is well-documented, and the molded body gives good coplanarity for pick-and-place. The operating range from -55 to +125 °C means this cap is specified for avionics, downhole, and other high-temperature environments, not just indoor electronics.
