18650 battery is the originator of lithium-ion batteries-a standard lithium-ion battery model set by SONY in Japan in order to save costs, where 18 means a diameter of 18mm, 65 means a length of 65mm, and 0 means a cylindrical battery.
What is a Switched Reluctance Motor?09 July 2024
Switched reluctance motor is a type of speed-regulating motor developed after DC motor and brushless DC motor. Product power levels range from several watts to hundreds of kilowatts, and are widely used in household appliances, aviation, aerospace, electronics, machinery, and electric vehicles.
Antenna: Principles, Performance Parameters and Classification15 November 2021
An antenna is a transducer that takes a guided wave propagating on a transmission line and transforms it into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa. It is a component used in radio equipment to transmit or receive electromagnetic waves.
What is an Electrical Connector?19 November 2025
Electrical Connector is an electromechanical component that connect the electrical circuit. It is composed of a fixed female contact (socket), and a free male contact (plug). According to the shape, there are circular electrical connector and rectangular electrical connector, and each type can be subdivided based on the connection method...
How Many do You Know About the 12 Components Included in the Circuit Board?12 February 2022
We are lucky to live in an era where electronic devices are readily available. These electronic devices, on the other hand, come to us thanks to the incredible components on the circuit board, and we frequently wonder what makes electronic devices operate, how they achieve such massive success, and how they accomplish it. Electronic devices are incredible things; you can't see what's going on within them, but you can see what they're capable of. We'll talk about the wonders of PCBs and how to get past them to construct the circuit board in this article.
Dismantling and Analyzing Each Component in the Switching Power Supply16 February 2022
Switch Mode Power Supply (SMPS for short), also known as switching power supply, switching converter, is a high-frequency power conversion device and a type of power supply. Its function is to convert a level of voltage into the voltage or current required by the user through different forms of architecture.
What is speaker?08 October 2021
Hi, fellas. Welcome back to the new post today. The speaker is a type of transducer that converts electrical signals to auditory signals. The sound quality is greatly influenced by the speaker's performance. This article introduces some basic knowledge of the speaker.
Basics of Phase Change Memory05 February 2021
Phase change memory (PCM) is an advanced non-volatile memory technology recently sold in a computer system as storage-class memory. For non-von Neumann computing, such as in-memory computing and neuromorphic computing, PCM is also being investigated.
New Crisis in Semiconductors: Neon Gas Prices Soar 9 Times21 March 2022
According to MoneyDJ, the war between Russia and Ukraine has halted the operations of the Ukrainian industry, which supplies half of the world's neon gas, and the price of neon has soared nearly nine times in China. Neon is a key raw material for chip manufacturing, which has cast a shadow over the global semiconductor supply.
RF Modulator: Working Principle and Development Trend21 April 2021
An RF modulator is an electronic device that provides a baseband signal, which is used to convert radio frequency resources.There are many RF modulators available, but all functions work in a similar way.
What is Brushless DC Motors (BLDC) ?03 April 2025
Brushless DC (BLDC) motors represent a significant advancement in electric motor technology, combining high efficiency with superior performance characteristics. Unlike their brushed counterparts, BLDC motors eliminate mechanical commutation components in favor of electronic commutation systems, resulting in enhanced reliability and operational longevity. These motors have become increasingly prevalent across various industries due to their excellent torque-to-weight ratio, improved electrical efficiency, and precise control capabilities (Miller & Hendershott, 2022).
What is UWB (Ultra-wideband)?04 June 2021
UWB (Ultra-wideband) technology is a wireless carrier communication technology, which does not use a sinusoidal carrier, but uses the non-sinusoidal narrow pulse of the nanosecond level, so the spectrum range is wide.
