What is a 18650 Lithium Battery?15 December 2021
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.
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...
Detailed Explanation About Twenty Kinds of Capacitor08 November 2021
Hello everyone, I am Rose. Today I will introduce 20 kinds of capacitor to you. I will illustrate them in three or four aspects: Structure, features, Usages, advantages and disadvantages.
What are Fiber Optic Patch Cables?11 February 2022
Hello everyone, I am Rose. Today I will introduce fiber optic patch cables to you. Optical fiber communication, as an emerging technology, has become one of the main pillars of modern communication and plays a critical role in modern telecommunication networks, thanks to the rapid growth of traffic data.
What are Varactor Diodes?04 August 2020
Varactor Diodes, also known as "variable reactance diodes", are made using the characteristic that the junction capacitance varies with the applied voltage when the PN junction is reverse biased. When the reverse bias voltage increases, the junction capacitance decreases, on the contrary, the junction capacitance increases.
Introduction to Optical Amplifier27 March 2025
An optical amplifier is a subsystem product that can amplify optical signals in optical fiber communication systems. The principle of the optical amplifier is basically based on the stimulated radiation of the laser, which realizes the amplification effect by converting the energy of the pump light into the energy of the signal light.
Diode Basis: Symbol, Types and Applications25 February 2022
Hello everyone, I am Rose. Today I will introduce diode to you. A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). It has unidirectional conductivity, that is, when a forward voltage is applied to the anode and cathode of the diode, the diode conducts. When a reverse voltage is applied to the anode and cathode, the diode is turned off.
What is RF Filter?09 December 2021
Hello, I am Rose Welcome to the new post today. The radio frequency filter is a filter circuit made up of capacitors, inductors, and resistors that is used to filter the signal frequency in communication channels. The filter allows signals that meet a specific frequency to pass while suppressing unwanted frequency signals.
An Overview of Digital Signal Processor23 July 2020
A digital signal processor (DSP) is a processor composed of large-scale integrated circuit chips to complete digital signal processing tasks. Digital signal processing is the theory and technology of representing and digitally processing signals. Digital signal processing and analog signal processing are a subset of signal processing.
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.
An Overview of Photoelectric Sensors12 June 2020
The photoelectric sensor is a key component of photoelectric conversion in various photoelectric detection systems. It is a device that converts optical signals (visible and ultraviolet laser light) into electrical signals. There are many types of photoelectric sensors that use photoelectric elements as sensitive elements, and they are widely used. Photoelectric devices include photocells, photomultiplier tubes, photoresistors, photodiodes, phototransistors, photocells, etc.
Solid State Relay Basics: Working, Features and Structure17 September 2020
Solid State Relay (SSR) is a non-contact switch composed of microelectronic circuits, discrete electronic devices, and power electronic power devices. The isolation device is used to realize the isolation between the control end and the load end. The input terminal of the solid state relay uses a tiny control signal to directly drive a large current load.
