  Title: Understanding Disc Capacitors – Structure, Working & Applications Disc capacitors are among the most commonly used passive components in electronic circuits due to their reliability, compact size, and cost-effectiveness. Whether you're a student, hobbyist, or engineer, understanding disc capacitors is essential for building and analyzing electronic systems. 📌 What is a Disc Capacitor? A disc capacitor is a type of ceramic capacitor shaped like a small, flat disc. It is made by coating both sides of a ceramic disc with conductive metal layers and attaching two wire leads for connection. The entire unit is often coated with an insulating layer, usually made of epoxy resin. ⚙️ Construction and Working Dielectric Material : Ceramic (usually made from barium titanate or similar materials) Shape : Flat, circular disc Electrodes : Metal plates on both sides of the disc Encapsulation : Protective epoxy coating Leads : Two metal leads extend from the sid...

Understanding Ceramic Capacitors – A Key Component in Modern Electronics Ceramic capacitors are among the most widely used types of capacitors in modern electronic circuits. Whether you're repairing a smartphone, designing a microcontroller-based project, or building a power supply circuit, you’re almost certain to come across ceramic capacitors. But what makes them so popular? Let’s explore what ceramic capacitors are, how they work, their types, and their common applications. 📘 What is a Ceramic Capacitor? A ceramic capacitor is a non-polarized capacitor that uses a ceramic material as the dielectric. It stores electrical energy between two conductive plates, separated by this insulating ceramic material. The ceramic dielectric can be composed of various materials like titanium dioxide or barium titanate, which determine the capacitor’s electrical properties. ⚙️ How Does It Work? When a voltage is applied across the terminals of a ceramic capacitor, an electric field is...

  Understanding Electrolytic Capacitors: Types, Applications, and Benefits In the world of electronics, capacitors are essential components that store and release electrical energy. Among the various types of capacitors, electrolytic capacitors stand out for their high capacitance values and compact size, making them a popular choice in power supply circuits and audio equipment. Let’s dive into what electrolytic capacitors are, how they work, their types, applications, and advantages. 🔌 What is an Electrolytic Capacitor? An electrolytic capacitor is a polarized capacitor that uses an electrolyte (a conductive liquid or gel) to achieve higher capacitance values compared to other capacitors of similar size. It has two terminals: positive (anode) and negative (cathode) . The anode is usually made of aluminum or tantalum and is coated with an insulating oxide layer that acts as the dielectric. 🛠 How Does It Work? The working principle of an electrolytic capacitor is simila...
