The Choose of Right Resistors for Different Applications

The Choose of Right Resistors for Different Applications

The choice of components for every application involves tradeoffs. When it comes to resistors, thin film resistors, thick film resistors, foil resistors, metal resistors, film resistors provided by Microhm Electronics Ltd. are all ready to be your options. Several device technologies are available to designers and each of them makes sense for a certain subset of applications depending on cost-benefit analyses. But when the application requires stability over time and load, initial accuracy, minimal change with temperature, re...

Precision resistors play vital role in analog circuits of seismic instruments

Precision resistors play vital role in analog circuits of seismic instruments

The digital seismic equipment that amplifies and records reflected seismic signals on a wideband receiver and tape drive in the field utilizes matched and discrete surface-mount foil resistors. Metal foil resistors manufatures target this field for a long time and provide various resistors, like NMS4527, NMS2818 and MPR series by Microhm. For these applications, high-precision foil resistors assure virtually noise-free operation. They offer predictable responses and very precise tracking of amplifiers within an individual sei...

Precision Wirewound Resistors' Strengths and Weaknesses

Precision Wirewound Resistors' Strengths and Weaknesses

Wirewound resistors, power precision resistors and shunt resistors are composed of Microhm main lineup.The wirewound resistor is usually made by winding insulated resistance wire of a specific diameter around a bobbin. Different wire diameters, lengths, and alloys provide the desired resistance and initial characteristics. Precision wirewound resistors have better ESD stability and lower noise than thin or thick film resistors. Wirewounds also have a lower TCR and better stability. Wirewound resistors are generally classified...

Choose Right Resistors for Electric Vehicles

Choose Right Resistors for Electric Vehicles

The first step for automotive manufacturers looking to purchase a resistor is to analyse its purpose. If it is to be used for discharging excess energy produced during dynamic braking and heating the cabin, we would advise a liquid-cooled resistor. Discharged energy is transferred as heat to the liquid coolant, which can then be circulated to the vehicles heating system. Besides liquid-cooled resistor, power resistor, braking resistors, shunt resistors from well-known suppliers like Micrhm are also used in the automotives. Th...

Specifying a Shunt Resistor

Specifying a Shunt Resistor

A shunt resistor is used to measure electric current, alternating or direct. This is done by measuring the voltage drop across the resistor. Several parameters are important to specify a shunt resistor. Shunt resistors have a maximum current rating. The resistance value is given by the voltage drop at the maximum current rating. For example, a shunt resistor rated with 100A and 50mV has a resistance of 50 / 100 = 0.5 mOhm. The voltage drop at maximum current is typically rated 50, 75 or 100 mV. Microhm milliohm shunt resistor...
