The TPSE158M004R0075 is listed as Active by KYOCERA AVX — no last-time-buy clock, no end-of-life notice. This is a current-production part you can spec into a new design without worrying about an imminent EOL.
1500 µF at 4 V — the bulk decoupling workhorse
The 75 mOhm ESR is low enough to handle ripple current without excessive self-heating, but high enough to avoid the low-ESR oscillation issues that can plague ceramic-only decoupling networks.
Temperature range and field-fit
Rated for -55 °C to 125 °C — this is the full military/industrial temperature band. It survives cold-soak in an outdoor base station and the under-hood heat of an engine bay ECU. The molded case in 2917 (7343 Metric) footprint is a standard SMT package. No special handling beyond normal tantalum precautions — polarity is clearly marked on the case, and the reflow profile follows standard JEDEC MSL-3 guidelines. Size code E is the largest case in the TPS series — it packs the highest capacitance into the 2917 footprint, which means fewer parallel capacitors to hit your target bulk value.
Tolerance and sourcing reality
Tape & Reel packaging means it feeds straight into a pick-and-place line. No manual handling required for volume assembly.
