150 µF bulk decoupling — 6.3 V rail, 250 mOhm ESR
The TPSC157M006R0250 is a molded tantalum capacitor from the TPS series, rated 150 µF at 6.3 V with a maximum ESR of 250 mOhm. This combination suits it for output filtering on low-voltage DC-DC converters or as bulk decoupling on a 3.3 V or 1.8 V rail where the ripple current and voltage margin align with a 6.3 V rated part. The 250 mOhm ESR limits the self-heating under ripple current — a lower ESR would run cooler, but this value is typical for a C-case tantalum at this capacitance and voltage. Check the ripple current derating curve in the TPS series datasheet against your load profile.
The 2312 (6032 Metric) case size, 6.00 mm x 3.20 mm footprint with a seated height of 2.80 mm, fits standard PCB layouts for C-case tantalum capacitors. The molded package is compatible with reflow soldering profiles.
