Structure, Types and Working of Dry Cell04 March 2021
A dry cell is an electrical power generator dependent on chemical reactions. The cell pushes the electrons to fluid from one end to the other when the two electrodes are bound in a closed way. The electron flow allows the electrons to flow into the closed system.
What are the Types and Dielectric of Ceramic Capacitors?19 February 2020
A ceramic capacitor is also called a monolithic capacitor, whose dielectric material is ceramic. According to the different ceramic materials, it can be divided into two types: low-frequency ceramic capacitors and high-frequency ceramic capacitors. According to the structure, it can be divided into wafer capacitor, tubular capacitor, rectangular capacitor, a chip capacitor, feedthrough ceramic capacitor and so on.
What is Semiconductor Package?06 December 2021
Semiconductor package is the process of assembling integrated circuits into chip final products. Simply put, it is to put the integrated circuit die (Die) produced by the foundry on a substrate that plays a supporting role, lead out the pins, and then fix the package into a whole.
What is NAND Flash?04 November 2021
NAND Flash is a better storage device than hard disk drives and is particularly evident in low-volume applications up to 4GB. As the quest continues for lower power consumption, lighter weight, and better performance, NAND is proving to be very attractive. Its development goal is to reduce the cost per bit of storage and increase storage capacity.
Top 10 Popular Semiconductor Companies in 202214 January 2022
The semiconductor industry is made up of businesses that design and manufacture semiconductors and semiconductor devices like transistors and integrated circuits. It was founded around 1960, when semiconductor device manufacture became a viable enterprise. Since then, the industry's yearly semiconductor sales revenue has risen to more over $481 billion in 2018. This article presents the top 10 most popular semiconductor companies in 2022.
What is the DC Bias Characteristic of a Capacitor？25 July 2022
Hello everyone, I am Rose. Welcome to the new post today. Today I will tell you what is the DC bias characteristics of a capacitor.
Circuit Breaker: Working Principle, Types and Structure04 August 2020
Circuit breaker is a switching device capable of closing, carrying and breaking the current under normal and abnormal circuit conditions within a specified time. So what's its structure and how many types are there? How does it work? Read this.
What is a 555 Timer?09 April 2025
555 Timer is an integrated circuit chip that is often used for timers, pulse generators, and oscillating circuits. 555 can be used as a delay device, a trigger, or a starting resonator element in a circuit.
What is RF Power Amplifier?14 December 2021
Hello everyone, I am Rose. Today I will introduce RF Power Amplifier to you. The radio frequency power amplifier (RF PA) is a critical component of many wireless transmitters, and its significance is self-evident.
What is CPLD (Complex Programmable Logic Device)?31 December 2021
CPLD uses CMOS EPROM, EEPROM, flash memory, and SRAM programming technology, thus constituting a programmable logic device with high density, high speed, and low power consumption. They are relatively large in scale and complex in structure and belong to the range of large-scale integrated circuits.
General PCB Layout Design Guidelines for RF and Digital-to-Analog Circuits20 January 2022
This article provides guidance and advice on radio frequency (RF) printed circuit board (PCB) design and layout, including some discussion of mixed-signal applications such as digital, analog, and RF components on the same PCB. The content is organized by topic to provide "best practice" guidelines that should be applied in conjunction with all other design and manufacturing guidelines that may apply to specific components, PCB manufacturers, and materials.
What is Time Delay Relay?11 October 2021
Hello everyone, I am Rose. Today I will introduce Time Relay to you. A Time Relay is an electrical component that is used on a circuit with a lower voltage or lower current to turn on or off a circuit with a higher voltage and bigger current or to regulate a higher voltage or larger power. This article will introduce some basic knowledge of Time Relay.
