I am Kevin Chen, I graduated from University of Electronic Science and Technology of China in 2000. I am an electrical and electronic engineer with 23 years of experience, in charge of writting content for ICRFQ. I am willing use my experiences to create reliable and necessary electronic information to help our readers. We welcome readers to engage with us on various topics related to electronics such as IC chips, capacitors, resistors, inductors, circuit breakers, diode, transistor, module, relay, opticalcoupler, connectors, PCBs, etc. Please feel free to share your thoughts and questions on these subjects with us. We look forward to hearing from you!
Image of mobile home source Bob Vla One way of protecting your home from the dangers associated with electricity is by installing a circuit breaker. People refer to them using different names such as breaker boxes, service panels load centers among other. One thing is common is they are designed for safety and functionality. Circuit…
Imae source Skar Audio After buying your amplifier, the next thing to focus on is the wire selection. You should always use the right gauge of wire for your amplifier. Amplifiers are usually rated by their wattage while wire are rated by their sizes(gauge) In this case, we are looking at the 1200 watt amp.…
Open and closed circuit diagram. Source EdrawMax Open and closed circuits. What do they mean and why should I know about them? Just as the name suggests, the difference is based on the possibility of electric current to flow or not to flow. An open current will allow the current to flow. A closed circuit,…
You have two button cell batteries to choose, CR1220 and BR1220. Which one should you choose? This dilemma is quite common among most buyers. This is because the two batteries are similar in many aspects and at the same time are used in the same application areas. To make the right choice, you will have…
Image source : circuits today There are different types of resistors used for the electronics applications. They are usually ranked according to the type of material used, or the resistive material. These materials include tungsten, brass, Nichrome and platinum. Due to the fact that these metals have less resistivity, carbon has always proven to be…
Image source: Elecrow WS2811 and WS2812 are two major LED drivers or ICs that have dominated the LED market. Most of the LED fixtures today are run by these chips. They are called drivers because they are designed to control the intensity and behavior of the LED lighting fixtures. Despite being used for the same…
Image source: safety capacitors All about circuits I know I need a capacitor for my electric circuit. But do I really need a safety capacitor? As long as you want to be assured the safety of your electric circuit, getting a safety electronic component will always be necessary. Even if it means getting yourself a…
Image source: battery equivalents SR626SW is small button cell battery that is commonly used in watches, medical devices, cameras, among an array of portable electronic devices. The small size of the battery allows it to fit into compact and portable devices. Despite the small size, it delivers adequate power to run these devices, not forgetting…
Image source: circuit digest Pull up and pull down resistor are two types of resistors designed to create a stable voltage on the signal line. These resistors rectify or correct the input voltages of the digital signals and stop them from staggering randomly in cases where there is a no input bias. We all know…
Image source: Support Articles We are in the digital era where image matters. Billions of images are posted everyday on various web platforms. In fact, image has evolved to be a critical format of passing messages. But, have you ever thought of the process of getting that image to the form that it is? How…
