Sampling PTC Heater in Resistance Heating Method

Sampling PTC Heater in Resistance Heating Method

The resistor needs to be heated during use. Our resistance heating is the technology that generates heat when the current passes through the resistor. The heat is transferred to the object to be heated by heat conduction. The resistance heating method is widely used in semiconductors and automobiles, agriculture, national defense, household appliances and other industries. The correct resistance heating method can make the resistance heating uniform, the thermal efficiency is high, and the environmental pollution is less, whi...

Why should the Resistor be Derated When Applied to the Power Line?

Why should the Resistor be Derated When Applied to the Power Line?

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...

Method for Distinguishing Metal Film Resistance from Carbon Film Resistance

Method for Distinguishing Metal Film Resistance from Carbon Film Resistance

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 ...

Does the Change in the Power Battery Industry Change the Demand for Resistors?

Does the Change in the Power Battery Industry Change the Demand for Resistors?

The power battery industry is changing, and whether it will set off a multi-bone Nomi effect in the industrial chain. Upstream supply systems, including precision resistors , capacitors, shunts, lamination machines, and drying equipment, are quietly diverging. Taking lithium batteries as an example, the future development of enterprises that enter the top ten power battery customers will be relatively comfortable, especially for lithium battery suppliers that bind large customers and become their main suppliers. According to ...

Factors Affecting the Rated Power

Factors Affecting the Rated Power

In the specifications of all Microhms resistors, power derating curve is a must. It shows the relationship between rated power and terminal temperature. Higher ambient temperatures can significantly reduce the rated power. This effect is called derating. The rated power of a resistor means the max amount of energy it can dissipate without failing or degrading. The maximum power rating of Microhm s shunts is 36W, precision resistor MVR can reach 50W. What will affect the rated power of resistors .Lets figure it out. 1. The Res...

What is a shunt in electronics?

What is a shunt in electronics?

Microhm Electronics Ltd. is professional in SHUNTS for your diverse applications. A shunt is an element that is used in a circuit to redirect current around another part. The areas of application vary widely. For some applications, electrical devices other than resistors can be used. A few examples are given to illustrate the diversity of shunts. Shunt resistors, some time called ammeter shunt or Current shunt resistors, are low resistance precision resistors used to measure AC or DC electrical currents by the voltage drop t...
