The TPME687K006R0018 is a molded tantalum capacitor from KYOCERA AVX's TPM series, delivering 680 µF capacitance at 6.3 V with an ESR of just 18 mOhm in the 2917 (7343 Metric) case size. The 18 mOhm ESR is the headline number here — it keeps ripple heating low and supports higher ripple current than standard tantalum capacitors in the same footprint, which matters for point-of-load converters and FPGA core rail decoupling.
The molded case (Type Molded) provides mechanical stability and moisture resistance compared to conformal-coated tantalums, reducing the risk of silver migration in high-humidity environments.
