Unless you have been living under a rock for the last 12 months, the following news will not be new to you - yet affecting your life tremendously, especially if you are working as an engineer or a supply chain manager: Back at the beginning of 2017, major manufacturers of ceramic chip capacitors began to realise that the demand for MLCCs was stronger than expected.
According to the MLCC: FY 2018 Global market Outlook, this situation has even intensified due to a rising demand for high capacitance MLCC, as next generation products in multiple segments were viewing MLCC in the 100, 220 and 330 range as standard parts.
The most cost effective solution had been and probably would continue to be for the next ten years; the stacking of ceramic, but anywhere that other dielectrics can be employed, demand will grow as manufacturers have no choice but to distance themselves from such a tremendous reliance on Ceramics.
Polymer electrolytic capacitors are mainly used in power supplies of integrated electronic circuits as buffer, bypass and decoupling capacitors, especially in devices with flat or compact design.
Especially the SP-CAPs and POS-CAPs with their small size factor and cubical form are the go to products when it comes to the replacement of MLCCs.
