Multi-Layer Ceramic Capacitor (MLCC) for Flexible Electronics

Multilayer ceramic capacitors (MLCC) are very small valued capacitors consisting of multiple layers of ceramic material that act as a dielectric. MLCCs are highly preferred in satellite and military applications due to their high capacitance and low cost. Through the filtering of unwanted noise and ripples, MLCCs are used in voltage regulators and power supplies. MLCCs act as interference preventers in decoupling circuits to isolate one circuit from another. MLCCs are used to stabilize the frequency of oscillators and provide accurate timing signals in timer circuits. They are also used to tune circuits to specific frequencies and reject unwanted signals in RF filters.

Nanostructured Ceramics for Capacitors

Nanostructured ceramics have gained attention for their unique properties and potential applications in various fields, including capacitors. The term “nanostructured” refers to materials that have features at the nanometer scale, and these features can lead to enhanced electrical, mechanical, and thermal properties. Here are some aspects related to the use of nanostructured ceramics in capacitors:


In conclusion, the study of the development of MLCC has evolved from a fundamental scientific curiosity to a promising avenue for technological innovation with far-reaching implications across multiple industries. Ongoing research continues to uncover new materials and techniques, bringing us closer to unlocking the full potential of MLCC in our quest for more efficient and sustainable technologies.
