MMS5930 is ideal for current sensing in industrial, medical and automotive applications

MMS5930 is ideal for current sensing in industrial, medical and automotive applications

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 selection for engineers' design

Shunt resistors selection for engineers' design

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...

Considerations for choosing precision resistors

Considerations for choosing precision resistors

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...

Resistors for  Passive Balancing in Battery-Powered System

Resistors for Passive Balancing in Battery-Powered System

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, ...

Resistors Ensure  the Accurate of Medical Apparatuses

Resistors Ensure the Accurate of Medical Apparatuses

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...

Choose Right Resistor for Different Applications

Choose Right Resistor for Different Applications

One of the most common components that every professional or hobbyist circuit designer encounters is to choose trusty electrical resistors from resistor manufactures as Microhm Electronics. A resistors job is to convert electrical energy, either DC or AC, into thermal energy by having higher resistance than the typical electrical conductor used in a circuit. By doing so, they can control the current flow through or voltage drop across them, offering a handy way to manipulate such things in an electronic circuit. In fact, its ...

Current Detection of 5W Shunt Resistors in Automotives

Current Detection of 5W Shunt Resistors in Automotives

Resistors in current detection applications are typically used to detect overcurrent conditions or remaining battery level. And although current sense resistors have been widely adopted in the automotive and industrial sectors, the recent trend towards greater sophistication and computerisation has increased current requirements, leading to a need for high power components. This includes a demand for high accuracy resistors with superior temperature coefficient of resistance (TCR) for stable operation in extreme temperature e...
