220 µF, 40 mOhm — why this cap gets specified
The TPME227M016S0040 is a molded tantalum capacitor from KYOCERA AVX's TPM series, rated 220 µF at 16 V with a 40 mOhm equivalent series resistance.
Temperature range and deployment
Rated from -55 to +125 °C, this cap fits avionics, downhole instrumentation, and satellite power buses where the ambient swings beyond the commercial range. The 2917 (7343 Metric) case, size code E, is a standard footprint — the same pad pattern serves many TPM-series values, so a layout change for a different capacitance keeps the same land pattern.
Active — no last-time-buy pressure
New designs can commit to this part without an obsolescence risk window.
