33 µF, 300 mOhm ESR — bulk decoupling ceiling
A 300 mOhm ESR at 33 µF means the cap can absorb a few hundred mA of ripple before self-heating becomes a concern; above that, you parallel two or step to a lower-ESR polymer tantalum.
The molded case and the TPS series construction handle the thermal cycling without cracking the dielectric.
Active production — standard sourcing
The 2312 (6032 Metric) case and C size code are common footprints, so the supply base is broad.
