Automotive-grade tantalum for under-hood and chassis electronics
Its AEC-Q200 qualification (cite:) places it in the automotive reliability track — suitable for engine control units, transmission modules, and sensor interfaces that see under-hood ambient temperatures. The 2.1 Ohm ESR at 100 kHz (cite:) is the figure to budget for ripple current and self-heating in a DC-link or bulk decoupling role — higher ESR than a ceramic MLCC, but the tantalum construction delivers stable capacitance under DC bias, which Class II ceramics lose.
Package and footprint — size code B in 1411 metric
The capacitor uses the manufacturer size code B (cite:), which corresponds to a 1411 (3528 Metric) case (cite:) — 3.50 mm x 2.80 mm footprint with a seated height of 2.10 mm max (cite:,). Surface-mount reflow profile follows standard tantalum recommendations; the molded body is compatible with both reflow and wave soldering processes.
