A ceramic MLCC of the same capacitance would have an ESR below 10 mOhm, but it would also lose 80% of its capacitance under DC bias — this tantalum holds its value across the full 6.3 V rated voltage. If you are replacing a ceramic with this part, the higher ESR means the self-heating under ripple is real; check the ripple current derating against the ambient temperature. ## Temperature range and board placement It can sit next to a hot MOSFET on a motor drive or inside a sealed outdoor telecom enclosure without a capacitance roll-off curve — the solid electrolyte construction keeps the dielectric constant stable across the band. The 1206 case is a standard footprint; the 1.80 mm seated height fits under a 2 mm board-to-board clearance. The TPS series is a standard catalog line from KYOCERA AVX.","metaTitle":"TPSA685M006R1800 KYOCERA AVX Molded Tantalum Capacitor 6.8","metaDescription":"TPSA685M006R1800 KYOCERA AVX TPS series molded tantalum capacitor, 6.8 µF ±20%, 6.3 V, 1.8 Ohm ESR, 1206 case, -55°C to 125°C.
