33 µF at 10 V — the ESR is the real spec
A 33 µF cap with 500 mOhm ESR can handle roughly 400 mA ripple at 100 kHz before the internal temperature rise hits the datasheet limit; above that, the ESR dominates the thermal budget.
Molded case, size code C — what it means at the bench
Package is 2312 (6032 metric), 6.00 mm x 3.20 mm footprint, seated height 2.80 mm max. Size code C is the standard case for 33 µF at 10 V in the TPS family. The molded case reworks cleanly — hot air at 260°C for 10 seconds lifts the part without lifting the pad, provided the board has a thermal relief on the cathode pad.
Active production — no LTB worry
Product status is Active per KYOCERA AVX. This BOM line can be ordered without obsolescence risk for current production.
The 125°C ceiling is the upper limit for the tantalum dielectric; derate voltage above 85°C per the standard tantalum derating curve.
