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.

Kemet Webinar

Ceramic capacitors are usually described with a 3-character designation like X7R, X5R, and C0G, but what do those designations that mean? There’s a lot behind the scenes of this simple combination of letters and number when it comes to temperature.

In this webinar, KEMET’s Wilmer Companioni (Senior Technical Marketing Manager) takes you...

Measured data collected during the study showed that the bias dependence for the same nominal part from different vendors can be very different. Moreover it was shown that bias sensitivity of X7R parts is not necessarily better than that of X5R parts, sometimes not even from the same vendor.
