Alloy resistance is a kind of patch resistance, mainly current-limiting function.

Alloy resistance according to the material can be divided into several categories:

First: manganese copper alloy, this kind of products are relatively high stability, mainly concentrated in the resistance value below 0.004R. Good stability.

Second: ferrochrome aluminum alloy, ferrochrome aluminum alloy is mainly concentrated in 0.004R and above the resistance value. Good stability.

Third: copper alloy, conventional alloy resistance value can be.

Fourth: nickel copper alloy, conventional alloy resistance value can be.

Fifth: nickel chromium alloy, conventional alloy resistance value can be.

Sixth: Karma alloy, conventional alloy resistance value can be, this material cost is the highest, so few manufacturers.

Seventh: ceramic alloy, 0.001R below the size can not be produced, but can do high resistance value, know 0.75R can, the specific volume corresponding to the resistance value will be different.

Alloy resistance Due to the strong conductivity of the metal, so the resistance is generally low such as 1 milliohm, 10 milliohm, 100 milliohm, etc. So it is often used to sample the current in the circuit. Used to feedback the changing current in a circuit in order to further control or influence the change in current. Mainly used products such as: battery protection board, power supply, frequency converter, lamps, motors, etc.
