The 2.5 Ohm ESR is the equivalent series resistance at 100 kHz — it sets the ripple current the part can handle before self-heating becomes a derating factor. For a 35 V rail that sees a 100 mV pk-pk ripple at 100 kHz, the ripple current is about 40 mA RMS; at 2.5 Ohm ESR the internal dissipation is roughly 4 mW, well within the part's thermal budget at 85°C ambient. No last-time-buy window is in effect, and no successor has been announced. The molded case provides mechanical protection and moisture resistance consistent with a general-purpose surface-mount tantalum. Dimensions are 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. The 2.10 mm height is a constraint for low-profile assemblies — confirm the board-to-cover clearance before committing.","metaTitle":"TPSB155M035S2500 KYOCERA AVX Molded Tantalum Capacitor 1.5","metaDescription":"TPSB155M035S2500 active molded tantalum capacitor, 1.5 µF ±20%, 35 V, 2.5 Ohm ESR, -55°C to 125°C.
