Shunt resistors have been integrated in the parallel form with the component or instrument in order to divert the electrical current. Such kinds of resistors are designed to give alternative path for current in case there is a failure. They can be used to reduce input sensitivity coming from the input lines proceeding directly to the ground.Current shunt resistors were generally low in resistance and passive electronic devices used to measure AC (alternating current) and DC (direct current) going through the voltage drop in which currents created throughout resistance.
Shunt resistor electrical specifications include power rating, temperature coefficient of the resistance, resistance tolerance, current rating, ohms, and power rating. Ohm is measuring the opposition of the material to the electricity circuit flow while the TCR or temperature coefficient of resistance is referring to resistance change with temperature change.
Surface Mount Resistors
PCR or the power coefficient of resistance is referring to a temperature. This temperature rises because of self-heating. In terms of current-sensing shunts, resistance is usually ranging in between 100 µO and 500 mO. A shunt resistor can be applied in current conversion. This is the aspect in which high precision has been required.

Shunt resistors’ physical specifications come in different forms. But these include the lead type as well as the resistor materials. A shunt resistor can be surface mounted, chassis mounted, through-hole mounted, and bolted. Through-hole technology (THT) and surface mount technology (SMT) have been the other typical and well-known mounting styles. Other lead types available are axial leads, radial leads, gull-wing leads, screw terminals, J-leads and tab terminals.
There is also a shunt resistor that has no leads. These are the wire wound, thick film, metal alloy, thin film, ceramic, metal film, metal oxide and carbon film. Carbon shunt resistors were composed of resistive, ceramic, solid and high temperature materials that were bonded by metal contacts.
DC Current Shunts
Metal alloy shunt resistors got more than two metallic elements. On the other hand, a wire wound shunt resistor contains thin wire winding in the ceramic rod. Each shunt resistor becomes unique in the area of packing because of passive electronic components that were packed in tape reel assemblies. This includes carrier tape which had embossed cavities for individual component storage. Others have been packed in trays (or trails) and they had been made up of carbon-power and fiber materials as they molded in rectangular outlines containing uniformly spaced matrices of pockets. Some of them have been packed in a tray (trail) and were comprised of both fiber and carbon-power materials. At the same time, these are molded in a rectangular form that has numerous pockets which were uniformly spaced.
