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.

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.

Capacitors are used in both analog and digital circuits to remove unwanted signals. The filtering performance of a capacitor or filtering circuit is commonly described in terms of insertion loss. Some of the factors that significantly affect the insertion loss performance of a filtering circuit include configuration of the filtering elements, impedance, and load current.
