The TPSC227K006A0070 is a molded tantalum capacitor from the KYOCERA AVX TPS series, rated at 220 µF with ±10% tolerance and a 6.3 V voltage rating. The 70 mOhm ESR is the key parameter for ripple current handling — at this impedance, the capacitor can absorb and deliver transient energy without excessive self-heating, making it a fit for bulk decoupling on 3.3 V or 1.8 V supply rails in power management circuits.
The molded case in a 2312 (6032 Metric) footprint (6.00 mm x 3.20 mm, seated height 2.80 mm) is a standard surface-mount size that reflows on a conventional profile without special handling.
