Wirewound Resistors Features

Wirewound Resistors Features

Wirewound resistors are common seen in power supplies and other equipment where lots of power is dissipated. A high-resistance wire is wound on an insulating form usually a ceramic tube and attached to electrodes at each end. These are made to dissipate a lot of power in sizes from one-watt to hundreds of watts. Wirewound resistors are usually intended to be air cooled, but some styles have a metal case that can be attached to a heatsink or metal chassis to get rid of undesired heat. Microhm Nual Series are metal clad wirewou...

Current Sampling Resistors

Current Sampling Resistors

In the circuits, low value resistors sense when the current is too high so that measures can be taken upstream before the excess current causes damage. Wirewound resistors are a popular choice for these applications. They are inexpensive, available in low resistance values, have low temperature coefficients and good surge-handling capability. Microhm has served this application for years with their power resistors. Now, Microhms new NS series resistors add an additional application advantage. We designed them for PC board su...

Through Hole Resistors' Usages and Edges

Through Hole Resistors' Usages and Edges

A through-hole resistor is a two terminal passive element that comes with a long, flexible lead that can be inserted into a PCB board. The technology used to insert resistors in PCBs is of two types, i.e. axial type and radial type. Through hole resistors find applications in alternative energy, consumer electronics, computers, and telecommunications. Rise in technology advancements, and increased usage of high configuration systems drives growth of the through-hole resistors market. Through hole resistors provide high mechan...

Why Choose Low Inductive Resistors?

Why Choose Low Inductive Resistors?

Since resistors are made of conductive materials, they, too, exhibit inductance as an unwanted, parasitic effect. This effect is especially noticeable if the resistor is made out of wire formed into a coil shape. Depending on the application, resistor inductance might be easily disregarded, especially in DC circuits. However, parasitic resistor inductance can be a significant factor in high-frequency AC applications. The reason for this is that the impedance of a resistor rises with the applied voltage frequency due to the in...

Precision Shunt MMS8420 for Current Sensing

Precision Shunt MMS8420 for Current Sensing

Precision shunts are very precise resistors placed on a circuit in order to measure the current flowing through that circuit. MMS8420 will handle a full-scale current of 600 amps with resistance 0.1m, power at 36 watts. The shunt does this by providing a very small voltage drop across its resistance proportional to the current flowing through the shunt. This can be clarified using Ohms Law, which states that the voltage will be equal to the current multiplied by the resistance (E=IR). Shunts are typically rated according to ...

Resistors for Wind Power Generation Systems

Resistors for Wind Power Generation Systems

Load test resistors one of the most important applications is wind-form installation. Utilizing the wind is one of the cleanest, most sustainable ways to generate electricity. Wind power produces no toxic emissions and will not bring negativie impact on global temperature. Meanwhile, wind power is one of the most abundant and increasingly cost effective energy resources makes it a viable alternative to burning coal or oil. Pre-insertion resistors, neutral earthing resistors, dynamic braking resistors, Microhm load test resis...
