Ceramic Capacitors

Category Introduction

A capacitor is a passive electronic device that stores electric charge. Ceramic capacitors consist of two or more alternating layers of ceramic material as the dielectric and metal layers acting as the non-polarized electrodes. Applications include automotive, bypass, decoupling, filtering, RF, and ESD protection. Through-hole versions are often disc or "blob" shaped with two wire leads.

About Ceramic Capacitors

What are Ceramic Capacitors?

Ceramic Capacitors

Ceramic capacitors are a type of fixed-value capacitor where the ceramic material acts as the dielectric. They are widely used in electronic circuits for their ability to store and release electrical energy. The basic operating principle involves two conductive plates separated by a ceramic dielectric. When a voltage is applied, an electric field is created across the dielectric, causing a charge to accumulate on the plates. This stored charge can then be released when needed, making ceramic capacitors essential for filtering, buffering, and timing applications in electronic devices.

Types of Ceramic Capacitors

1. Multilayer Ceramic Capacitors (MLCCs)

MLCCs are the most common type of ceramic capacitors, consisting of multiple layers of ceramic and metal. They are known for their high capacitance per unit volume, making them ideal for applications requiring compact size and high performance. MLCCs are used in a wide range of applications, from consumer electronics to automotive systems, due to their reliability and efficiency.

2. Ceramic Disc Capacitors

These capacitors are characterized by their disc-shaped ceramic dielectric. They are typically used in high-voltage applications and are known for their stability and low cost. Ceramic disc capacitors are often found in power supply circuits and radio frequency applications.

3. High Voltage Ceramic Capacitors

Designed to handle high voltage levels, these capacitors are used in applications such as power transmission and distribution systems. They are built to withstand high electric fields and are often used in industrial equipment and medical devices.

How to choose Ceramic Capacitors?

When selecting ceramic capacitors, consider the following key parameters:

Capacitance Value: Determine the required capacitance based on the application needs.
Voltage Rating: Ensure the capacitor can handle the maximum voltage in the circuit.
Temperature Coefficient: Choose a capacitor with a suitable temperature coefficient for the operating environment.
Size and Form Factor: Consider the physical size constraints of the application.
Dielectric Type: Select based on the desired performance characteristics, such as stability and tolerance.

To evaluate product quality and reliability, review supplier certifications, customer reviews, and test reports. Consider environmental factors like humidity and temperature, and ensure proper installation to avoid mechanical stress and thermal expansion issues.
