Shunt resistors have been integrated in the parallel form with the component or instrument in order to divert the electrical current. These types of resistors provide alternative current paths in case there have been problems or failure and these are used for complete reduction of input sensitivity from the input lines through the ground.A current shunt resistor is a low resistance and passive electronic device that is used to measure AC (alternative current) and DC 9direct current). This is directly proceeding to the voltage drop in which currents created all throughout the resistnace.
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.
Current Sense Resistors
The power coefficient of resistance or PCR is the temperature that arise because of self-heating. In terms of current-sensing shunts, resistance is usually ranging in between 100 µO and 500 mO. Shunt resistors have been utilized in the applications of current conversion in which high precision has been required. The physical specifications for the shunt resistors involve resistor materials and lead type. The shunt resistors may be bolted, surface mounted, through-hole mounted, and chassis mounted.

Surface mount technology (or SMT) and through-hole technology (or THT) were both common styles of mounting. The other kinds of lead are screw terminals, J-leads, and tab terminals. There are also gull-wing leads, radial leads, and axial leads available. Shunt resistors without leads are also available and they can be wire wound, metal film, metal oxide, carbon film, ceramic, metal alloy, thin film, and thick film. Carbon shunt resistors were composed of resistive, ceramic, solid and high temperature materials that were bonded by metal contacts.
Wirewound Resistors
Metal allow shunt resistors have 2 or more elements while a wirewound shunt resistor has thin wire winding in a ceramic rod. Shunt resistors differ in terms of packing methods because some passive electronic elements are packed in the reel tape assemblies along with a carrier tape which embossed cavities for storing individual component. Some were packed in trails (trays) have been composed of fiber and carbon-power materials while they have been molded in a rectangular outline containing matrices of pockets that are uniformly spaced.
