The TPSD227M006R0050 is a molded tantalum capacitor from KYOCERA AVX's TPS series, rated at 220 µF capacitance with a 6.3 V DC voltage rating and a low 50 mOhm ESR.
It suits designs that must operate reliably in avionics, satellite, downhole drilling, or outdoor telecom equipment where ambient extremes are the norm rather than the exception.
