Ceramic Capacitor Dielectrics Explained: C0G, X7R, Y5V and How to Choose14 July 2026
A ceramic capacitor is also called a monolithic capacitor, whose dielectric material is ceramic. According to the different ceramic materials, it can be divided into two types: low-frequency ceramic capacitors and high-frequency ceramic capacitors. According to the structure, it can be divided into wafer capacitor, tubular capacitor, rectangular capacitor, a chip capacitor, feedthrough ceramic capacitor and so on.
In-depth Analysis of the Global Semiconductor Supply Chain20 January 2022
The epidemic has led to a sudden surge in demand for digital products and technological advances. The millions of digital devices we use, from smartphones to electric cars, computers, robots, and the businesses they enable, all owe their existence to complex chips built on semiconductors. The global digital economy is estimated to account for up to 22.5% of global GDP.
What is an Oxygen Sensor?24 April 2025
The oxygen sensor is an essential component on engines using three-way catalytic converters to reduce exhaust pollution. It uses ceramic sensitive elements to measure the oxygen potential in the exhaust duct of the car. There are two kinds of oxygen sensors in practical application: zirconia oxygen sensor and titania oxygen sensor.
Types, Structure, and Packages of Integrated Circuits23 October 2025
The type of integrated circuit can be divided according to its use, function, structure, manufacturing process, integration, and conductivity type. The structure of the integrated circuit can be learned from levels from top to bottom: system level - module level - register transfer level (RTL) - gate level - transistor level. The packaging forms of integrated circuits include SOP, PGA, BGA, DIP.
An Overview of Thermal Overload Relays12 October 2020
Thermal overload relays are protective electrical appliances used for overload protection of motors or other electrical equipment and electrical circuits, The thermal overload relay is mainly used for overload protection of asynchronous motors. After the overload current passes through the thermal element, the bimetallic sheet is heated and bent to push the action mechanism to drive the contact...
How to Design Reliable High-Side Switching Circuits with P-Channel MOSFETs?22 July 2025
This article provides a comprehensive guide to designing reliable high-side switching circuits using P-channel MOSFETs, drawing from a real-world failure case shared by a Reddit user. The main issue identified was that the user's 48V system damaged the MOSFET because the gate-source voltage exceeded the device's ±20V limit (reaching -48V), and the article offers complete solutions including proper MOSFET parameter selection, using Zener diodes to clamp gate voltage, optimizing driver circuit resistor values for faster switching, and adding flyback diodes for inductive load protection, serving as a practical design roadmap for beginners in power switching applications.
Structure, Types and Working of Dry Cell04 March 2021
A dry cell is an electrical power generator dependent on chemical reactions. The cell pushes the electrons to fluid from one end to the other when the two electrodes are bound in a closed way. The electron flow allows the electrons to flow into the closed system.
What is a Fixed Inductor?15 April 2021
Fixed inductors are a classification of inductors according to their structure, and fixed inductors are commonly used inductive devices. An inductor with a fixed inductance is called a fixed inductor (or a fixed coil), and it can be a coil with a single layer, multiple layers, honeycomb type, or a magnetic core. These coils are winded on the magnetic core using a wire of corresponded diameter and they are packaged with epoxy resin or plastic according to the inductance and the maximum DC operating current.
Optical Image Stabilization (OIS) Explained: Types and Working21 May 2021
In cameras or other imaging instruments, optical image stabilization (OIS) refers to the setting of optical components to avoid or reduce instrument jitter in the process of capturing optical signals, thereby improving image quality.
What is Digital Counter?01 September 2020
Counting is one of the simplest basic operations. In digital logic and computing, the counter is the logic circuit that realizes this kind of operation. In the digital system, the counter mainly counts the number of pulses to realize the functions of measurement, counting, and control.
What Determines the Maximum Operating Frequency of a Diode?29 June 2022
Hello, wish you a wonderful day. In this essay, we first pose the following query: what determines the diode's maximum operating frequency? In regards to the solution, the first thing we need to understand is that the junction capacitance and the reverse recovery time of the diode are two distinct concepts. The charging and discharging times of the junction capacitance cannot match the reverse recovery time. You say that, why? Let's start by taking a look at these facts.
