Lithium-ion Battery: Structure, Working Principle and Package08 November 2025
Hello everyone, I am Rose. Welcome to the new post today. Lithium battery is a kind of battery with lithium metal or lithium alloy as positive/negative material and non-aqueous electrolyte solution.
What is RF Power Amplifier?08 November 2025
Hello everyone, I am Rose. Today I will introduce RF Power Amplifier to you. The radio frequency power amplifier (RF PA) is a critical component of many wireless transmitters, and its significance is self-evident.
What is Amplifier?08 November 2025
Hello everyone, I am Rose. Today I want to introduce amplifier to you. An amplifier is a device that can amplify the voltage or power of an input signal, and is composed of tubes or transistors, power transformers and other electrical components. Used in communication, broadcasting, radar, television, automatic control and other devices.
Introduction to DC Amplifier07 November 2025
An amplifier that can amplify DC signals is called a DC amplifier. A DC amplifier amplifies a DC signal or an alternating signal that changes very slowly with time.
Introduction to Acceleration Sensors07 November 2025
An acceleration sensor is a sensor that can measure acceleration. It is usually composed of a mass block, damper, elastic element, sensitive element and an adaptive circuit. During the acceleration process, the sensor uses Newton's second law to obtain the acceleration value by measuring the inertial force applied to the mass. According to the different sensitive elements of the sensor, common acceleration sensors include capacitive, inductive, strain, piezoresistive, and piezoelectric type.
Power Semiconductor Procurement After the Nexperia Shake-Up—NXP for Stability, ON for Technology, or Nexperia for Value?04 November 2025
The recent supply chain turmoil surrounding Netherlands-based Nexperia has sent shockwaves through the global semiconductor industry, forcing procurement professionals to re-evaluate their sourcing strategies.
Characteristics and Working Principle of IGBT31 October 2025
IGBT, Insulated Gate Bipolar Transistor, is a composite fully controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and IGFET, (Insulated Gate Field Effect Transistor). It has the advantages of both the high input impedance of MOSFET and the low on-voltage drop of GTR.
What are Weight Sensors?31 October 2025
A weight Sensor is a device that converts the quality signal into a measurable electrical signal output. When using the sensor, we must first consider the actual working environment, which is very important for the correct selection of the weight sensor. Besides, it's also related to whether the sensor can work normally, its safety and service life, and even the reliability and safety of the entire weighing instrument.
Working Principle and Development of Magnetic Sensors31 October 2025
A magnetic sensor converts changes in the magnetic properties of sensitive components caused by magnetic fields, currents, stresses, strains, temperatures, light, etc. into electrical signals, and detects devices of corresponding physical quantities in various ways.
What is an Inductive Sensor?31 October 2025
An inductive sensor is a device to realize non-electric measurement by using the change of coil self-inductance or mutual inductance. Using inductive sensors, displacement, pressure, vibration, strain, flow and other parameters can be measured. It has a series of advantages such as simple structure, high sensitivity, large output power, small output impedance, strong anti-interference ability, and high measurement accuracy, so it is widely used in the electromechanical control system.
50 World Famous Sensor Manufacturing Companies31 October 2025
In recent years, the world sensor market has been developing stably, and companies all over the world are racing to accelerate the development and industrialization of sensors. Eastern Europe, Asia Pacific and Canada have become the fastest-growing regions in the sensor market, while the United States, Germany, and Japan still occupy the largest sensor market. Here we’re going to introduce the top 50 well-known sensor manufacturing companies in Europe, North America and Asia.
What is a Capacitive Sensor?31 October 2025
Capacitive sensors use various types of capacitors as sensing elements. It is a conversion device that converts the measured physical or mechanical quantities into changes in capacitance which is actually a capacitor with variable parameters. Capacitive sensors are widely used for measurement of displacement, angle, vibration, speed, pressure, composition analysis, medium characteristics, etc.
