Active production — a molded tantalum for 35 V rails
The TPSB105K035H2000 is a molded tantalum capacitor in the TPS series from KYOCERA AVX, rated 1 µF at 35 V with ±10% tolerance and 2 Ω ESR. The 2 Ω ESR is the key design constraint: for a 1 µF bulk decoupling cap on a 35 V rail, the ripple current capability is limited by that ESR, so verify the ripple current budget before committing the BOM position.
Package and footprint — 1411 / 1210, 3.50 mm × 2.80 mm
Package size is 0.138" × 0.110" (3.50 mm × 2.80 mm) with a seated height of 0.083" (2.10 mm), fitting the 1411 (3528 Metric) and 1210 footprints. The B-size code matches the standard tantalum case code — confirm the pad geometry against the manufacturer's recommended land pattern for reflow assembly. Supplied in Tape & Reel (TR), ready for automated pick-and-place. The molded construction and surface-mount package are standard for reflow soldering; no special handling beyond typical MSL precautions is expected.
The part is currently in the KYOCERA AVX catalog and can be ordered against an RFQ for the BOM quantity.
