Capacitor/MLCC: A Complete Guide to Function, Types, and Applications

In the world of electronics, one of the most important components is the Capacitor/MLCC. Whether you are using a smartphone, laptop, TV, or even a car, you are directly depending on capacitors to make your device work smoothly. A Capacitor/MLCC (Multilayer Ceramic Chip Capacitor) is widely used in modern electronics because of its reliability, compact size, and efficiency.

This article explains what a Capacitor/MLCC is, how it works, its different types, advantages, challenges, and applications across industries.

What is a Capacitor/MLCC?

A capacitor is an electronic component that stores electrical energy temporarily and releases it when needed. It consists of two conductive plates separated by a dielectric material.

The term MLCC (Multilayer Ceramic Chip Capacitor) refers to a special type of capacitor that uses multiple ceramic layers stacked together to increase capacity in a very small size. Today, MLCCs are found in Interface - Sensor and Detector Interfaces almost all consumer and industrial electronics.

Simple Example:

• In a smartphone, Capacitor/MLCC helps maintain voltage stability.
  
  
• In computers, it ensures smooth power supply to processors.
  
  

How Does a Capacitor/MLCC Work?

The working principle of a capacitor is simple:

1. Charging – When a voltage source is applied, the capacitor stores energy in the form of an electric field.
   
   
2. Storage – Energy remains stored until the capacitor is needed.
   
   
3. Discharging – The stored energy is released to power the circuit when required.
   
   

In the case of Capacitor/MLCC, multiple ceramic layers are stacked, which increases energy storage while keeping the size very small.

Types of Capacitor/MLCC

Capacitors come in many forms, and MLCC is one of the most widely used. Below is a comparison:
