I learned from this forum few weeks ago that the capacitance of a MLCC will be lower if a dc bias applied across it. Some of the MLCC I have are 10uF and they are quite expensive (based on the price quoted in Farnell) compared to those with values lower t...

DC Bias Characteristic The challenge lies not with spontaneous polarization, but in reversing it. When spontaneous polarization is reversed under no voltage stress (no DC bias), MLCCs achieve a high capacitance. However, if an external bias is applied to ...

Hi, im designing for an LDO vreg which specifies a X5R/X7R ceramic output filter of 10uF with less than 0.2R or ESR. When I search digikey and look at the datasheets almost no MLCCs have an ESR spec - and if they do it is a 'typical ESR curve' and does no...
