What is a Motor Starter?26 December 2025
A motor starter is an electrical system used to safely start and stop a motor. Like a relay, the motor starter turns power on/off, which offers low voltage and overcurrent safety, as opposed to a relay.
Introduction to Coupling Capacitor04 February 2021
A capacitor which is used to link one circuit's AC signal to another circuit is referred to as a coupling capacitor. Blocking the DC signal and allowing the AC signal from one circuit to another is the main feature of this capacitor. In different circuits where AC signals are used for output, these capacitors are used, while DC signals are simply used to supply power to components of the circuit, so they do not come out in the output.
MediaTek, Qualcomm Announce Joining Russia Sanctions10 March 2022
Russia and Ukraine are in a fierce war. Various countries around the world have sanctioned Russia, and many companies have responded. After TSMC announced a ban on exports to Russia in compliance with U.S. trade agreements, Taiwan's IC design leader MediaTek and U.S. Qualcomm followed suit and banned exports of chips to Russia.
RGB LED: Circuit, Difference and Application25 March 2021
White LED and RGB LED are the same in essence. They both hope to achieve the effect of white light, but one is directly presented in white light, and the other is made by mixing red, green and blue light. RGB lamps are integrated with the three primary colors. In addition, there are blue LEDs with yellow phosphors, and ultraviolet LEDs with RGB phosphors. On the whole, both have their imaging principles. The colors of some LED backlight panels are particularly clear and vivid, even to the level of high-definition TVs. This situation is exactly the characteristic of RGB, which advertises the characteristics of red as red, green as green, and blue as blue. In terms of color mixing, it has more diversified characteristics.
What's the Difference Between Operational Amplifier and Comparator?01 April 2022
Hello everyone, I am Rose. Welcome to the new post today. Today I will introduce the difference between operational amplifier and comparator to you.
Introduction to Reluctance Motor08 March 2021
This is a kind of advanced motor that, like a regular electric motor, has both a stator and a rotor. This motors use a direct spinning magnetic field (RPM) to synchronize the rotor's speed with the stator's RMF. These motors offer a high power density at a low cost, making them appealing in a variety of applications. The reluctance motor's operating theory is that if a magnetic material is placed inside a magnetic field, it often pulls itself into line in the least reluctance manner.
Introduction to BGA Package07 December 2021
BGA (Ball grid array) package is a high-density surface-mount technology. At the bottom of the package, the pins are all spherical and arranged in a grid-like pattern, hence the name BGA.
What is Solid-state Battery08 March 2021
A solid-state battery is a battery that uses solid electrodes and solid electrolytes. Solid-state batteries generally have low power density and high energy density. Because of the relatively high power and weight of solid-state batteries, it is an ideal battery for electric vehicles.
What are Comparators?03 December 2020
Comparing two or more data items to determine whether they are equal, or determining the size relationship and arrangement order between them is called comparison. A circuit or device that can realize this comparison function is called a comparator.
What is a Transmitter?12 October 2021
In industrial process control, measurement and transmission unit, actuator, and regulator are the three major components of the entire control system. Among them, the measurement and transmission unit is the transmitter, and sometimes the transmitter is actually equivalent to the sensor. The actuator is like a valve, and the regulator is the controller, which is the brain of the entire control system.
What is G.654E Fiber?24 May 2022
Hello everyone, I am Rose. Today I will introduce an optical fiber to you.
Chip Packaging Lead Time Has Grown to 50 Weeks07 April 2022
British chip design firm Sondrel warned of problems in chip packaging, revealing that package lead times had increased from about 8 weeks previously to 50 weeks or more.
