100 µF, 10 V, 200 mOhm — bulk decoupling in a 2917 footprint
The TPSY107K010R0200: The 200 mOhm ESR keeps ripple heating manageable in power-supply output filtering and bulk decoupling roles — a 1 A ripple current at 100 kHz dissipates 200 mW, well within the part's thermal budget when the board copper carries the heat. The -55°C to 125°C operating range covers industrial and military-temperature environments — the capacitance and ESR shift with temperature per the tantalum dielectric characteristic, but the 200 mOhm ESR at 25°C rises roughly 1.5× at -55°C and drops to about 0.8× at 125°C, so the filter corner frequency stays within 20% across the full range.
Active lifecycle, standard compliance
The part is RoHS-compliant per the TPS series standard material declaration.
Footprint and board integration
The molded body is polarity-marked with a stripe on the anode side; the cathode is the larger pad on the PCB. Surface-mount assembly with a standard reflow profile — the molded epoxy body withstands peak temperatures up to 260°C for 10 seconds per JEDEC J-STD-020.
