Bulk capacitance for low-voltage rails
The TPSV108M004R0035: The 35 mOhm ESR keeps ripple heating low and supports higher ripple current than higher-ESR parts in the same case size. Rated operating temperature from -55 °C to 125 °C covers industrial and military-temperature environments — the same part serves a telecom base station and a downhole tool without a grade change.
ESR and ripple-current fit
35 mOhm ESR at 100 kHz is the loss figure that sets self-heating and ripple-current capability. For a 4 V rail drawing 2 A ripple, the I²R loss is 140 mW — well within the 2924 package's dissipation without derating at 85 °C.
Active lifecycle and compliance posture
Supplied in tape-and-reel packaging for automated pick-and-place assembly. The 2924 case (7.30 mm × 6.10 mm footprint, 3.75 mm seated height) is a common high-capacitance tantalum size with established land-pattern guidance.
