The temperature coefficient of resistance, or TCR, is one of the main used parameters to characterize a resistor. The TCR defines the change in resistance as a function of the ambient temperature. The common way to express the TCR is in ppm/C, which stands for parts per million per centigrade degree. Microhm Electronics can provide resistors with TCR as low as 1ppm/K. Positive or Negative Temperature Coefficient of Resistance? Resistors are available with a TCR that is negative, positive, or stable over a certain temperature ...

Microhm Electronics has announced the lauch of MMS5930 series of low resistance, metal alloy current sense power resistors. With values down to 200 and a corresponding power rating on standard can be up to 10W, the maximum measurable current is over 200A, and hence in most cases restricted only by the capacity of the PCB tracks. Aimed at designers of power supplies and motor drives in the industrial, automotive and medical industries, Microhm Electronics MMS5930 high power shunt resistors are ideal in the specific areas of re...

Shunt resistors make up a category of resistors that create a low resistance path, and they are widely used to measure high currents thanks to their low resistance, such as Microhm Electronics MVR series and MMS series. Current measurement is required in many applications. For example, applications like over current protection, 4-20mA systems, battery chargers, high-brightness LED control, H-bridge motor control, or metrology need to monitor current. How to Calculate Shunt Resistance The technical constraints of shunt resisto...

Precision resistor generally refers to a resistor whose value is 1 percent, 0.5 percent or even lower. The percentage will be clearly stated in an unambiguous manner. However, this is only the starting point, as the actual resistance of a 1 percent, 100-ohm resistor is guaranteed to be between 95 ohms and 105 ohms only under ideal conditions. But real-world designs must function under real-world conditions. Voltage The Voltage Coefficient of Resistance (VCR) is the change in resistance with applied voltage. This is entirely d...

In the automotive and transportation marketplace, large battery stacks provide high output power without producing harmful emissions (that is, carbon monoxide and hydrocarbons) associated with gasoline-powered combustion engines. Ideally, each individual battery in the stack equally contributes to the system. However, when it comes to batteries, all batteries are not created equally. Even batteries of the same chemistry with the same physical size and shape can have different total capacities, different internal resistances, ...

Microhm Electronics thick film technology provides a high level of performance and stability in custom resistor networks. The usual hybrid technologies for manufacturing resistors depend upon composite materials that have limitations. Traditional thick-film methods severely limit performance characteristics and thin-film methods are limited in attainable ohmic values. Microhm Electroncis resistors offer the best characteristics of both methods. These resistors bear unprecedented design efficiency, versatility, linearity, sta...
