330 µF bulk decoupling on a 4 V rail
The TPSX337M004R0100: The molded case construction provides mechanical protection and moisture resistance during reflow, and the 2917 (7343 Metric) footprint is a standard large-case tantalum size that mates with common PCB layouts for power input filtering or output bulk capacitance on POL converters.
Temperature range and derating margin
Rated for -55°C to 125°C operation, the TPSX337M004R0100 covers the full industrial temperature envelope and the lower end of automotive ambient. The ±20% tolerance is standard for tantalum electrolytics; the actual capacitance at 125°C will drift higher, so the minimum capacitance at temperature still meets the decoupling target if the rail is designed for the -20% low end at 25°C.
Active lifecycle — no LTB pressure
The TPS series is a long-running molded tantalum family from KYOCERA AVX, so the risk of sudden obsolescence is low for a production BOM.
