150 µF bulk decoupling at 16 V with 100 mOhm ESR
The TPSE157K016R0100 is a 150 µF tantalum capacitor rated at 16 V, packaged in the standard 2917 (7343 Metric) case with manufacturer size code E. The 100 mOhm ESR is the key parameter for ripple handling in power rail decoupling — a lower ESR means less self-heating and better filtering of switching noise at the output of a buck converter or LDO. The ±10% tolerance is typical for tantalum electrolytics and sufficient for bulk storage and decoupling applications where the exact capacitance value is not critical to circuit timing.
Temperature range and construction
Rated for -55°C to +125°C operation, this capacitor suits industrial and automotive environments where the ambient temperature inside the enclosure can exceed 85°C. The molded case construction provides mechanical protection and consistent thermal performance during reflow soldering. The general-purpose feature set means no special low-ESR or high-reliability screening — it is a standard-grade tantalum for typical decoupling, filtering, and hold-up capacitor roles on a mixed-signal PCB.
