22 µF at 35 V — bulk decoupling with thermal margin
The TPME226K035R0100 is a molded tantalum capacitor from KYOCERA AVX's TPM series, delivering 22 µF capacitance at a 35 V rated voltage in the standard 2917 (7343 Metric) case size. The 35 V rating provides a comfortable derating margin above a 24 V bus — a common practice in power-supply decoupling and hold-up circuits where tantalum caps are preferred for their volumetric efficiency. With an ESR of 100 mOhm, this part handles the ripple current typical of a switching regulator input stage without excessive self-heating. The ±10% tolerance covers the range a BOM cost engineer expects for bulk decoupling — tight enough to keep the rail within regulation, loose enough to avoid premium sorting.
Mil-temp range and surface-mount footprint
The 2917 case measures 7.30 mm x 4.30 mm with a seated height of 4.30 mm, a footprint that matches standard reflow profiles for tantalum chip caps. The manufacturer size code E identifies the case dimensions within the TPM series — useful when cross-referencing a BOM that lists the size code instead of the full package string.
