Surviving the Shortage of MLCCs

Electronic devices need capacitors - a lot of them!

Capacitors are widely used to store energy, suppress filter noise, sense changes in capacitance, start motors, as well as for suppression, coupling and decoupling circuits. Multi-layer ceramic capacitors (MLCCs) have previously been the capacitors of choice, and since the back end of 2016 there’s been a significant jump in the requirement for these capacitors. For example, some mobile phones now require double the number of capacitors than their previous versions. This continued rise in demand ultimately places a great deal of pressure on the MLCC supply chain, causing production lead times to be pressed and prices to continue increasing for all MLCC product lines in the market. Deficiencies like this impact a number of industries, and unfortunately this shortage is forecast to continue for some time with no sign of resolution.

But, there is a solution – Polymer Capacitors!

Polymer capacitors meet the needs for high reliability, long life, stable performance, low ESR and low cost in a number of markets; such as enterprise, commercial, consumer, medical, aerospace, and now automotive as well. They can provide a viable alternative for various designs currently using MLCCs, and can even provide direct drop-in replacements for low capacitance, non AEC-Q200 compliant designs.

Find out all you need to know for updating your MLCC designs with Polymer capacitor replacements below and achieve:

  • Higher delivered capacitance for high current (≥ 1Amp) applications
  • MLCC acoustic noise reduction
  • Lower piece count leading to BOM cost reduction
  • Improved voltage stability
