Thick film resistors and thin film resistor , the most common types in the market, are characterized by a resistive layer on a ceramic base. Thick film resistor started to gain popularity In the 1970s. Today, these are by far the most used resistors in electrical and electronic devices. They come usually as chip resistor (SMD), and have the lowest cost compared to any other technology. The temperature coefficient of thick film resistor typically ranges from 50 ppm to 200 ppm/K. Tolerances are between 1% and 5%. Because costs ...

Wire wound resistors are the oldest type of resistors that are still manufactured today. They can be produced very accurate, and have excellent properties for low resistance values and high power ratings. A wire wound resistor is a resistor where a wire with a high resistivity is wrapped around an insulating core to provide the resistance. A wire wound resistor is an electrical passive component that limits current. The resistive element exists out of an insulated metallic wire that is winded around a core of non-conductive m...

When current is applied to a resistor, voltage drops at both end of the resistor according to Ohms law. You will get the current value applied to the resistor when you divide the voltage by resistance value. When you adjust the resistance large to make voltage drop large, heating of the resistor would be an issue. To avoid this, current sense should be achieved by using small resistance as possible. When the voltage drop is small, the voltage should be amplified by amplifying circuit. The purposes of current sense in a circu...

Though resistor marking may not display their value outright, most resistors are marked to show what their resistance is. PTH resistors use a color-coding system, which really adds some flair to circuits. Through-hole axial resistors usually indicate their value by color-band system. Most of these resistors will have four bands of color circling the resistor, five band and six band resistors are also can be found In the standard four band resistors, the first two bands indicate the two most-significant digits of the resistor...

Shunt resistors is applied with the primary purpose to measure current. However, the meaning of the term shunt in electronics is broader than that. A shunt is an element that is used in a circuit to redirect current around another part. The areas of application vary widely. For some applications, electrical devices other than resistors can be used. A few examples are given to illustrate the diversity of shunts. Protecting a circuit against overvoltage A method to protect a circuit from a too high voltage is using a crowbar ci...

Metal film resistors are axial resistors with a thin metal film as resistive element. The thin film is deposited on usually a ceramic body. The appearance of metal film resistors is similar to carbon film resistors, but their properties for stability, accuracy and reliability are considerably better. Metal film resistors are amongst the most common types of axial resistors. For a good reliability, metal film resistors are normally operated between 20 and 80 percent of their specified power rating. Reliability is generally inc...

Resistors characteristics are the features a resistor possessed, which determine the performance and application of a resistor. The main parameters consist of rated power, resistance range, resistance tolerance, nominal resistance, rated voltage and so forth. The rated power of a resistor means the max allowable power applied to the resistor in continual operation at specified ambient temperature. Usually, the type of resistor as a load is determined on the basis of the power consumption of the resistor. For instance, a squar...
