What does a zero-ohm resistor do?
Using zero ohm resistors reduce the cost of jumper wires insertion. For mass production, it’s important to keep the cost down. Using an additional machine for jumper wires results in a separate setup and process cost. Therefore, a zero-ohm resistor is the perfect alternative that saves cost and time in assembly.
What is the resistance of a zero-ohm resistor?
The resistance is only approximately zero; only a maximum (typically 10–50 mΩ) is specified. A percentage tolerance would not make sense, as it would be specified as a percentage of the ideal value of zero ohms (which would always be zero), so it is not specified.
Where is the resistance value on a resistor?
A resistor limits electrical current. Resistance is in ohms, often denoted by the omega symbol. In a schematic, the resistance value is usually included near to the symbol (shown). Click here to learn about reading resistor color codes.
What can a zero ohm resistor be used for?
A zero ohm resistor is often used for similar purposes and is essentially a link that can be machine placed. You might find that different variants of the board will have it in place while others have it removed, or on some boards they can be removed by the user for different operation.
Where do you find resistance in a schematic?
Resistance is in ohms, often denoted by the omega symbol. In a schematic, the resistance value is usually included near to the symbol (shown). Click here to learn about reading resistor color codes. A potentiometer, also known as a variable resistor, has a resistance value determined by the position of an internal wiper (shown by the arrow).
