1500 µF at 15 mOhm ESR — the low-impedance bulk cap for tight rails
The TPME158M002R0015 is a molded tantalum capacitor from KYOCERA AVX's TPM series, rated at 1500 µF with a 2.5 V voltage rating and ±20% tolerance. The 15 mOhm ESR is the standout number here — it keeps ripple current heating under control in a 2917 (7343 Metric) package that sits just 4.30 mm tall. A 1500 µF bulk cap with 15 mOhm ESR handles the ripple from a 2.5 V rail supplying a 1.8 V core regulator or a multi-GHz FPGA core — the low impedance means the capacitor absorbs the AC component without the can temperature climbing out of the derating curve.
Full military temperature band in a surface-mount case
The molded case and surface-mount 2917 footprint mean it survives the thermal cycling of avionics or downhole equipment without the lead fatigue of a through-hole part.
