How to Distinguish MOSFET? Is it N-Channel or P-Channel?23 December 2021
Hello everyone, I am Rose. Today I will teach you how to define N-channel and P-channel in MOSFET. Metal Oxide Semiconductor Field Effect Transistor (MOSFET) is a basic component of modern electronic goods and is abbreviated as FET.
What Is An Intrinsic Semiconductor?03 November 2020
An intrinsic semiconductor is a single crystal made from a pure semiconductor through a certain process. Intrinsic semiconductors are semiconductors with complete crystal lattices without any impurities. Its conductivity is not affected by any impurities or lattice defects, and is only determined by the nature of the semiconductor material itself.
Introduction to Potential Transformers21 September 2020
A potential transformer is a device used to transform voltage. The purpose to transform the voltage is mainly for measuring instruments, as the power supply of relays, measure the voltage, power, and energy of the line, or protecting the valuable equipment, motors, and transformers in the line when the line fails.
STM32U5: The Most Complex Low-power MCU19 January 2022
In March 2021, STMicroelectronics (ST) announced the STM32U5, and in September the first STM32U5 models were officially mass-produced, meaning that ST gave birth to the first ultra-low-power microcontroller to achieve both PSA Level 3 and SESIP 3 safety certifications.
Basic Introduction to Film Capacitors22 October 2025
The film capacitor is also called a plastic film capacitor. It uses plastic film as the dielectric. Depending on the medium, there are many types of capacitors, such as electrolyte capacitors, paper capacitors, film capacitors, ceramic capacitors, mica capacitors, and air capacitors. Film capacitors are widely used in analog signal cross-linking, power supply noise bypass (reverse cross-linking), and other places.
Tunnel Diode: Definition, Features and Tunneling Process25 August 2020
Tunnel diode, also known as Ezaki diode, is a crystal diode with tunnel effect current as the main current component. The tunnel diode is a semiconductor diode made of a mixture of gallium arsenide (GaAs) and gallium antimonide (GaSb).

Various Reasons for the Failure, Explosion and Burning of Tantalum Capacitors02 June 2022
Hello, Wish you have a wonderful day. Many clients frequently discuss tantalum capacitor explosions, particularly in switching power supplies, LED power supplies, and other industries. Tantalum capacitor burning or explosion is the most frustrating problem for R&D personnel, leaving them perplexed. Many R&D technicians are no longer willing to employ tantalum capacitors due to the risk of tantalum capacitor failure mechanisms. In truth, if we thoroughly comprehend the characteristics of tantalum capacitors, we can determine the causes of tantalum capacitor failure (burning or explosion). Tantalum capacitors aren't as frightening as they appear. After all, tantalum capacitors have a lot of advantages. The reasons for tantalum capacitor failure can be classified into two categories: tantalum capacitor quality issues and circuit design issues. The next article will provide you with a thorough introduction.
How to Understand the Oscilloscope Bandwidth?13 December 2021
When a user selects an oscilloscope for essential measurements, the oscilloscope's key characteristics are frequently the only criteria used to determine which oscilloscope to employ. An oscilloscope's most essential index parameters are:Bandwidth, Sampling Rate, Record length
Introduction to Mass Air Flow Sensor15 September 2020
Mass air flow sensor is one of the important sensors of EFI engines. It converts the inhaled air flow into an electric signal and sends it to the electronic control unit (ECU). As one of the basic signals for determining fuel injection, it is a sensor that measures the air flow into the engine.
Emerging Storage Technologies: MRAM, RRAM, and PCRAM08 January 2026
The semiconductor industry is turning to emerging memories that offer higher storage performance, lower cost, and the ability to move toward process miniaturization. Three of these memories stand out -- MRAM, RRAM, and PCRAM.
