Automotive-grade molded tantalum for harsh environments
ESR and ripple current — what the 1 Ohm spec means
With an ESR of 1 Ohm at 100 kHz, this capacitor handles moderate ripple currents typical of DC-DC converter output filtering. The ESR value directly sets the self-heating under ripple — keep the RMS ripple current below the manufacturer's derating curve to stay within the 125°C ceiling.
Package and footprint — size code B
Housed in the standard size B case (1411 / 3528 Metric), the part measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm. The surface-mount footprint matches the common 1210 pad layout, so it drops onto existing PCB designs without a layout change.
