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.
Tantalum Capacitors Explained: How They Work, Where They Fit, and How to Use Them Safely26 June 2026
Tantalum capacitors sit in an interesting spot in the design engineer's parts bin. They pack a large amount of capacitance into a small, stable, board-friendly package, yet they carry a reputation for failing dramatically when mistreated. Both halves of that reputation are true, and neither tells the whole story. Used within their ratings, tantalum capacitors are dependable workhorses; used carelessly, they can short and overheat. This guide walks through what they actually are, how the two main families differ, how they compare with aluminum electrolytic and ceramic parts, and the engineering discipline that keeps them reliable.
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.
Ceramic Capacitor Dielectrics Explained: C0G, X7R, Y5V and How to Choose07 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.
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.
High Voltage Capacitor Safety: The Ultimate Guide21 August 2025
Have you ever wondered about the silent powerhouses behind our modern electrical grids and advanced electronic devices? High voltage capacitors are precisely that – critical components capable of storing immense electrical charges, essential for everything from industrial power supplies to medical imaging equipment. But with great power comes great responsibility, and the handling of these components demands a profound understanding of safety. Ignoring proper procedures can lead to severe consequences, including electric shock, burns, or even explosions. In this ultimate guide, we’ll delve deep into the world of high voltage capacitors, exploring their types, applications, and, most importantly, the comprehensive safety protocols required for their safe handling, testing, and storage. We’ll cover everything from safe discharge methods to essential personal protective equipment, ensuring you’re equipped with the knowledge to work confidently and securely with these powerful devices.
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.
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.
What is Universal Serial Bus (USB)?12 June 2026
Universal Serial Bus (USB) is a serial bus standard and a technical specification for input and output interfaces. It is widely used in information communication devices. The latest generation is USB4, and its transmission speed is 40Gbit/s, the three-stage voltage is 5V/12V/20V, the maximum power supply is 100W.
