Metal Foil Resistor is an important part of Microhm Electronics product linup. We offer surfact mount type, like NMS2818,NMS4527,NSR series and MPR series, as well as radial type, including To247 type resistor, To218 type resistor and MVR series. The excellent properties for precision and stability are due to a combination of several characteristics, which are following from the design principles of the metal foil resistor. Foil resistors achieve a low TCR by taking advantage of two characteristics of the foil. The resistance...

Selecting the proper method for current sensing is not a difficult thing. There are few factors need to be considered for choosing the right method, like: 1. How much accuracy is needed? 2. DC or AC measurement or both? 3. How much power consumption is required? 4. What is the current range and bandwidth to be measured? 5. Costing. Other than those, acceptable sensitivity and interference rejection are also need to be considered. A low-value resistor in series is used to sense the current. When the current flow through a low-...

Resistors are produced with a wide variety of materials and manufacturing processes. Each resistor material has its typical properties and specific areas of use. The main types that are used in electrical engineering comprise metal film, metal oxide film and foil carbon composition, carbon film and wirewound. Here is some details about wirewound resistors, metal film resistors and metal foil resistors. Metal film resistors are usually made of Nichrome, but also other materials such as tantalum nitride is used. The resistive f...

Microhm Electronics announced to extend the resistance of E-Beam Welded Shunt resistors MMS8420 from 1 mohm to 2mohm to fit more applications. MMS8420 is designed for high current stable and accurate measurement in industrial and automotive applications. The shunt is an electron beam welded resistance element, sandwiched between large copper terminals with optional tin plating. Precision applications can make use of its 1% tolerance, 100ppm/C TCR, 1V/C thermal EMF and separate ground pins to reduce errors. The low measurement...

Illustrations of the benefits of low TCR may be found within thousands of successful applications. Lets review three application examples where low TCR offers certain performance advantages here. Precision Instrumentation High-accuracy digital multimeters manufacture might need a resistor component for a new series of 8.5- and 7.5-digit units. To achieve necessary 8.5-digit accuracy, the specified resistor needed to offer extremely low TCR, high-precision, repeatability, low thermal EMF, low noise, long-term stability and min...

A potentiometer is a manually adjustable variable resistor with 3 terminals. Two terminals are connected to both ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element. The position of the wiper determines the output voltage of the potentiometer. The potentiometer essentially functions as a variable voltage divider. The resistive element can be seen as two resistors in series(potentiometer resistance), where the wiper position determines the resist...
