Electromagnetic interference (EMI) refers to instances where undesirable electric currents interrupt or adversely affect the current that a particular electronic device is supposed to receive. These disruptions come in the form of electromagnetic noise, that of which may be externally sourced or caused by other components located within the device. Depending on the magnitude of EMI, the disruption can range from poor signal reception to outright component malfunctions and failure. In countless electrical systems and devices, it is important to have protection against EMI in order to maintain optimal operating conditions. In this blog, we will discuss EMI power line filters, allowing you to better understand how protection is upheld.

Transistors are common semiconductor devices found in numerous electronic assemblies, featuring three terminals that allow them to amplify or switch electronic signals and power. As a basic building block of modern electronics, transistors aid the operation of radios, calculators, computers, and other everyday devices that we rely on. Generally, transistors may be classified as either Bipolar Junction Transistors (BJT) or Field Effect Transistors (FET), each of which varies in its characteristics and functionality. To help you understand the use of transistors and their types, we will discuss them briefly.

While the design of a particular electronic device is paramount to its proper functionality, one of the most important aspects of design is to ensure that a device is capable of turning on. Without the ability for a device to properly switch on and be powered, all the advanced materials and components within the assembly are little more than paperweights. In order for a steady supply of voltage to be provided to a circuit and all of its connected components, printed circuit boards (PCB) utilize what are known as power planes.
