Small electronic components are essential parts used in various electronic devices. They include items like resistors, capacitors, and transistors, which help control electrical signals. These components are often found on printed circuit boards (PCBs) and play a crucial role in the functioning of gadgets such as smartphones, computers, and televisions. These components are typically measured in millimeters and can be made from materials like silicon and metal. Their small size allows for compact designs in modern technology, enabling the development of lightweight and portable devices. Understanding these components is vital for anyone interested in electronics and engineering.
