Introduction to TRIAC and TRIAC Dimmer10 September 2020
TRIAC is developed based on ordinary thyristors. It can not only replace two thyristors connected in parallel with reverse polarity, but also only needs one trigger circuit, which is an ideal AC switching device...
Basic Introduction to the Types of Capacitors16 October 2025
A variety of capacitors are used in the manufacture of electronic devices, and they play different roles in the circuit. There are many types of capacitors, such as fixed capacitors, variable capacitors, and trimmer capacitors, and fixed capacitors can be divided into ceramics, mica, paper, film, and electrolytic capacitors according to the different dielectric.
Electronic components in a smart watch15 May 2023
One of the consumer goods categories with the greatest rate of growth is wearables, which heavily rely on electronics miniaturization. Customers are becoming more and more reliant on smartphones and smartwatches that have a wide range of services, including those that measure their daily steps, display health metrics, schedule appointments, send emails, and more.
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.
An Overview of Digital Signal Processor31 October 2025
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.
Bearing: Features, Types and Uses08 February 2022
Hello everyone, I am Rose. Today I will introduce bearing to you. Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.
What are Graphene Transistors?21 October 2025
Graphene is a two-dimensional crystal. Its structure is very stable because carbon atoms are arranged in hexagons and connected to each other to form a carbon molecule.
What is a PIN Diode?04 February 2021
While diodes with a simple PN junction are by far the most common type of diode in operation, in a variety of applications, other forms of diode may be used. The PIN diode is one type that is used for a number of circuits. In a variety of places, this diode type is used. For RF switching, the PIN diode is very fine, and the PIN structure in photodiodes is very useful as well.
What are the Different Types of Fingerprint Sensors?16 December 2020
A fingerprint sensor is a key device to realize automatic fingerprint collection. Fingerprint sensors are classified into optical fingerprint sensors, semiconductor capacitive sensors, semiconductor thermal sensors, semiconductor pressure-sensitive sensors, ultrasonic sensors, and RF sensors according to the sensing principle.
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.
Silicon Carbide (SiC): The Third-generation Semiconductor Material30 August 2021
Silicon carbide (SiC) is the main development direction of the power semiconductor industry. It is the semiconductor material to make power devices. In the foreseeable future, new energy vehicles are the main application for silicon carbide power devices.
What are Varactor Diodes?24 November 2025
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.
