Background

A zero-ohm resistor is also called a bridge resistor, and is a special purpose resistor, and a 0-ohm resistor is not a true resistor with zero value, and an ohm resistor is a resistor with a very small resistance value. Because of the resistance value, the resistance value has the same error precision index as the conventional chip resistor. Two points in the design of the circuit board can not be connected by a printing circuit, the front surface of the circuit board is often connected by overlines, which are often seen in common boards, and in order to ensure the normal work of an automatic chip mounter and an automatic component inserter, the overlines are replaced by zero resistors. Specifically, the bridge resistor may not have any function in the circuit, but may be on the PCB for debugging convenience or compatible design reasons. Can be used as a jumper wire to avoid high-frequency interference (becoming an antenna) caused by using a jumper pin. When the parameters of the matching circuit are uncertain, the parameters are replaced by 0 ohm, and when the matching circuit is actually debugged, the parameters are determined and then replaced by elements with specific numerical values. The 0 ohm resistor is actually a resistor with a very small resistance value, when the current consumption of a certain part of circuit is required to be measured, the 0 ohm resistor is connected with the 0 ohm resistor and the ammeter, so that the current consumption is conveniently measured, the bridge resistor can be used for measuring large current and other use scenes, in short, the bridge resistor is widely used in the circuit, and is an important electronic component.
