4.7 µF, 35 V, 700 mOhm — molded tantalum for wide-temperature rails
The TPSB475M035R0700 is a molded tantalum capacitor from KYOCERA AVX's TPS series, rated at 4.7 µF with a 35 V DC voltage rating and ±20% tolerance. The 700 mOhm ESR defines the ripple current capability — for a 100 kHz buck converter output, the self-heating stays manageable when the RMS ripple current is kept below the derating curve for the 1411 (3528 Metric) B case size. The molded construction provides mechanical protection and moisture resistance compared to conformal-coated chips, though the package still requires a derating of applied voltage above 85°C per the manufacturer's application note.
Surface-mount footprint and temperature grade
Housed in a 1411 (3528 Metric) surface-mount package with B case code, the capacitor measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. The full military temperature range means the part can be deployed in engine-bay electronics or outdoor telecom cabinets without a temperature derating exception — the voltage derating still applies above 85°C, but the component itself is rated for the ambient.
