electronica China, lasting for three days, ringed down the curtain on Mar.22,2019 successfully. Microhm prepared elaborately and exhibited full range of resistors in the site. Customers from all over the world visited Microhm E5 - 5606, consulted resistors and experienced. Our staffs introductions of the features, applications and merits were brief and to the point. Customers not only stayed for a time in front of the reception to learn more about products, but also streamed into Microhms booth to have a close look of the mat...

Special resistors are a relatively rare type in our daily lives and are usually found in specific products. However, we also classify varistors and thermistors as special resistors. These two resistors are often seen on the power module, so what role do these two special resistors play in the power module? The power module circuit usually has AC-DC circuit design. The application of varistor and thermistor in this road is very important. Lets analyze the specific effects of these two resistors. First, the role of the thermist...

New energy vehicles use batteries as the power source. The operating current of the electronic control system of the car body is mostly between 1-100A. In special cases, there will be a short-time 200-300A current, and the starting current of the vehicle is even as high as 1500A. . In such a working environment, the milliohm resistance in the automotive electronic system is required to instantaneously receive high load power, which is a test of the performance of the resistor. Many automotive resistors use an etched alloy foi...

Resistance is the most abundant component in electrical equipment, but it is not the component with the highest damage rate. The most common resistance damage is open circuit, and it is rare for the resistance to become larger or smaller. Commonly there are carbon film resistors, metal film resistors, wirewound resistors and alloy resistors. How can we judge whether they are damaged in the circuit? What are the characteristics after they are damaged? This is the problem engineers encountered. Today we will study what features...

The resistors in the circuit always give us the feeling that it is always dull and boring, making people feel that the resistors are unpredictable. However, it is the resistors that are constantly transforming our lives. We are no longer sighing the magic of the resistors all the time. Sometimes we feel the fun of it without knowing it. Water heaters are already the electrical products commonly used in our homes. It brings convenience to peoples lives. Many often use but dont know how it works. R1 is the temperature-regulatin...

Many types of power products that come into contact with life use various types of resistors, including chip resistors and plug-in resistors, some of which are high-precision resistors and very inexpensive. In circuit design engineering, the resistors are typically derated in the power line design for customers safety. The derating of the resistor can improve the reliability of the product and achieve the full life of the resistor. The derating of resistors has its own rules in many product designs. Too much derating of resis...

New energy automotive technology generally includes battery management system ( BMS ), vehicle charger, inverter, vehicle controller VCU/HCU, pedestrian warning system, DC/DC, etc. As the core components of new energy vehicles, battery management, inverters (motor control, precision resistors, shunts) and vehicle controllers must have high safety and reliability. Sampling resistors have been around since the invention of electronic components in the last century, but applications have been limited initially due to process lev...

Color ring resistors are produced using different materials, and their functions and applications are different, but they are all labeled with the same color ring recognition method. In the absence of a resistor manufacturers instructions, how to correctly identify the type of resistance is very difficult for line engineers and maintenance personnel. Today we will talk about the method of distinguishing the carbon film resistance from the metal film resistance in the color ring resistance. First of all, we need to understand ...

Robots have entered our lives, and with the rise of AI artificial intelligence, more and more robots have entered our lives. There is now such an intelligent robot entering the parking lot of our daily production. This robot does not need to be in the car plate or the parking frame, it can be rotated, transferred and transported at the bottom of the vehicle to achieve the advantage of minimum area crossing. With the development of AI technology and intelligent hardware, namely precision shunt and resistor technology, the flex...
