How to Understand the Oscilloscope Bandwidth?13 December 2021
When a user selects an oscilloscope for essential measurements, the oscilloscope's key characteristics are frequently the only criteria used to determine which oscilloscope to employ. An oscilloscope's most essential index parameters are:Bandwidth, Sampling Rate, Record length
Lattice FPGA vs Competitors A Comprehensive Comparison09 June 2025
Compare Lattice FPGA with competitors like Xilinx and Intel. Discover its low power, compact size, and cost-effective solutions for IoT and automation.
Network Interface Card: Types, Functions and Buying Guide17 August 2021
Network Interface Card (NIC, also known as a network interface controller) is one of the most basic components in the local area network. It is the hardware device connecting the computer and the network. Whether it is a twisted pair connection, a coaxial cable connection, or an optical fiber connection, data communication must be realized with the help of a network interface card.
VRLA Battery: Working Principle, Capacity and Maintenance12 March 2021
VRLA batteries, which means Valve Regulated Lead Acid Battery was born in the 1970s. By 1975, a considerable scale of production had been formed in some developed countries, and industrialization was soon formed and put on the market in large quantities. Although this battery is also a lead-acid battery, it has many advantages compared with the original lead-acid battery, and is very popular with users, especially for those who need to install battery supporting equipment together (or a workshop). , Such as UPS, telecommunications equipment, mobile communication equipment, computers, motorcycles, etc.
Characteristics, Types, and Functions of Electrolytic Capacitors17 October 2025
Inside the electrolytic capacitor is an electrolyte material that stores electric charge. It has positive and negative polarity, which is similar to a battery, and it cannot be reversed. The positive electrode is a metal substrate with an oxide film. The negative electrode is connected to the electrolyte (solid and non-solid) through the metal electrode plate.
Wireless Charging Explained: Working and Standards26 May 2021
Wireless charging technology originates from wireless power transmission technology, which can be divided into low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method for charging mobile phones. High-power wireless charging often uses resonance (most electric vehicle charging uses this method) from the power supply equipment (charger) to transfer energy to the device that uses electricity.
Basic Introduction to Power Amplifier09 January 2026
Power amplifier refers to an amplifier that can generate the maximum power output to drive a certain load (such as a speaker) under a given distortion rate. The power amplifier plays a pivotal role of "organization and coordination" in the entire audio system, and to a certain extent dominates whether the entire system can provide good sound quality output.
Capacitor Signs: Decoding Symbols & Markings14 August 2025
Capacitor signs, symbols, and markings with our ultimate guide. Learn to identify polarity, decode value codes, and avoid common mistakes for safe and effective circuit work.
Introduction to Lead Acid Battery: Construction, Working Principle and Types04 March 2021
The rechargeable and secondary batteries category includes lead acid batteries. Despite the battery's low energy-to-volume and energy-to-weight ratios, it can deliver higher surge currents. This refers to the fact that lead acid cells have a high power-to-weight ratio.
SAW Filter: Introduction, Features and Applications30 December 2020
The Surface Acoustic Wave (SAW) filter is a passive band-pass filter made by using the piezoelectric effect and the physical characteristics of surface acoustic wave propagation. Its role is to filter and delay electrical signals. It has the advantages of small size, stable performance, strong overload capacity, low phase distortion, and no need to adjust, so it is used in televisions, video recorders, wireless data transmission systems and other fields.
Photocoupler Basis: Description, Applications and Working Principle29 September 2021
Hello, everyone. I am Rose. Welcome back to the new post today. Photocoupler is also known as optocoupler. To communicate electrical impulses, optocouplers employ light as a channel. It is frequently utilized in many circuits because it provides an excellent isolation effect on input and output electrical signals. After reading this article, you will have a clear understanding of Photocoupler.
How do We Select Automotive Relays?30 September 2020
A relay is an automatic control device whose output will have saltatory change when the input (electricity, magnetism, sound, light, heat) reaches a certain value. Automotive relays are relays used in automobiles. Such relays have high switching load power, high shock resistance and vibration resistance. Most power supplies in automobiles use 12V, and most of the coil voltages are designed to be 12V...
