PCB Components: A Comprehensive Technical Guide to Passive, Active, and Electromechanical Parts

This article provides an in-depth overview of the various PCB components that make up electronic circuits – from passive elements like resistors and capacitors to active semiconductors and electromechanical devices. Introduction Printed circuit boards (PCBs) are the foundation of modern electronic devices, and PCB components are the building blocks mounted on these boards. In every electronic gadget – from smartphones and computers to automobiles and industrial machines – you will find a PCB populated with various electronic components. These components are broadly classified into three categories:  1. Passive PCB components, such as resistors and capacitors, regulate electrical signals without amplification or switching functions.  2. Active PCB components, including transistors and integrated circuits (ICs), […]
