The majority of tantalum capacitors used today are based on a solid electrolyte cathode system, and there have been many advancements in technology to enable smaller sizes, increased capacitance, and lower equivalent series resistance (ESR). Due to the relatively large market size and multiple suppliers, product improvements and new products are regularly reported and introduced to customers worldwide.

Organic Capacitor (KO-CAP) is a solid electrolytic capacitor with a conductive polymer cathode capable of delivering ultra low ESR and improved capacitance retention at high frequencies. KO-CAP combines the low ESR of multilayer ceramic, the high capacitance of aluminum electrolytic, and the volumetric efficiency of tantalum into a single surface mount package.

The tantalum polymer SMD are solid-state capacitors that demonstrate no wear out mechanism when operated within their recommended guidelines. Unlike their MnO2 counterparts, polymer capacitors don’t need to be derated as aggressively. Under most conditions of consumer electronics devices, polymer capacitors only need about 10% derating.

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.
