In 1952 the IEC (International Electrotechnical Commission) decided to define the resistance and tolerance values into a norm, to ease the mass manufacturing of resistors. These are referred to as preferred values or E-series, and they are published in standard IEC 60063:1963. These standard values are also valid for other components like capacitors, inductors and Zener diodes. The preferred values for resistors were established in 1952, but the concept of the geometric series was already introduced by army engineer Renard in...

The electronics industry has evolved at a remarkable rate over the past two decades. New techniques and advances have helped shrink equipment size and have put pressure on manufacturers of discrete components, such as manufacture resistors, to develop devices that approach the ideal in performance. Naturally, not every engineer needs an entire high-performance package for their circuitry. Resistors with much poorer specifications can be used satisfactorily in many applications, so the question of need is divided into four ba...

Wirewound precision resistors have some important characteristics. First, they can have very tight resistance tolerances. 0.005% is commonly achieved, such as PWP/PWS series of Microhm Electronics. More important, they are stable maintaining their precision over time because they are made with stable materials. Their TCR (Temperature Coefficient of Resistance) is low (10ppm/C) and can be controlled by selecting special wire alloys. In the past, the bulk of the resistor market went to carbon composition products. They are not...

A wide range of precision shunts, designed for use with kilowatt-hour meters and other high-current applications where a high level of accuracy is required, is now available from Microhm Electronics. Current shunts are low resistance precision resistors used to measure AC or DC electrical currents by the voltage drop those currents create across the resistance. Sometimes called an ammeter shunt, it is a type of current sensor. The interchangeable shunts (FL) are used to multiply the measuring range of measuring instrument an...

Resistance measurement applications, for example using string pots to measure movement, measuring thermistors/RTDs for temperature, measuring the resistance on test samples, and many more applications, are often mentioned by users. This article involves resistors ultilizing in low resistance measurement. Microhm Electronics MPR series (LFS series), NMS series, MMS series are often seen in low resistance measurement situation. First, lets consider the cables which are connecting the device to be measured to the instrument: If ...

Current shunt resistors are low resistance precision resistors used to measure AC or DC electrical currents by the voltage drop those currents create across the resistance. For example. A current shunt whose resistance is 0.001 Ohms having a current of 50 Amps flowing through it will produce a voltage of 0.001 50 = 0.05 Volts or 50 mV (milliVolts). So by inserting a current shunt into a circuit whose current you want to measure your can find the current by measuring the voltage drop across the shunt. Then knowing the resista...
