Molded tantalum for rail decoupling in harsh environments
The TPSB685K016R1200 is a molded tantalum capacitor from KYOCERA AVX's TPS series, offering 6.8 µF capacitance with ±10% tolerance at a 16 V rating. On a 5 V rail with 100 mV p-p ripple, the capacitor sees roughly 83 mA ripple current, producing about 8 mW of internal heat, well within the molded case's dissipation limit.
KYOCERA AVX lists the TPSB685K016R1200 as Active. The B-size case (1411 / 3528 Metric) is a common tantalum footprint, so no unusual pad geometry or stencil aperture is required.
Case size and footprint fit
The 1411 (3528 Metric) / 1210 case code measures 3.50 mm × 2.80 mm with a seated height of 2.10 mm max. The B-size land pattern is standard across the TPS series — confirm the pad dimensions against your PCB layout before committing the BOM.
