With the continuing supply shortage for multi-layer ceramic capacitors (MLCCs), designers are being forced to consider alternatives. In this article, we will look at the factors to be considered if you’re thinking about using polymer capacitors as a replacement. There has been a supply shortage of MLCCs since the end of 2016 and there are no signs of immediate improvement.

Depending on what units we express l and A in we get different units of r. A common way is by expressing l in m(eter) and A in mm2 r then gets the unit W´mm2/m. If we instead choose l in m and A in m2, the unit for r will be W´mm2/m, which usually is transformed to Wm. That unit often is used for non-metallic materials. If we know the value of r expressed in W´mm2/m, that value has to be multiplied by the factor 10-6 to give the value in Wm. Thus, 10-6 x W×mm2/m = 1 Wm.

MLCC capacitors are dominating today’s capacitor market enabling high grade of electronics miniaturization. The continuous downsizing and use of higher and higher dielectric constant materials for MLCC class II capacitors have however resulted in worsening of some electrical parameters stability such as capacitance drop at operating conditions. Thus, in consequence, what can be considered as an enabling technology for consumer and wearable applications may pose some risk if used in critical applications such as automotive, safety, medical or industrial sector, that are also in need for continuous miniaturization.

Würth Elektronik Webinar

For automotive application, need a design engineer more information about the used passive component in compared with an industrial application. However, what means if manufacturer declares AEC-Q200? Is that certified? Is that enough for the application? Where is the trust level for such “certificates”? We will answer these and your personal questions...
