What is a jumper resistor? Is the resistance value of a 0 ohm resistor with 5% accuracy and 1% accuracy the same? 1

Crossover resistor, commonly referred to as 0 ohm resistor or zero ohm resistor, is a special type of FM1208S-200CC resistor. Its nominal resistance is 0 ohms, mainly used as a connection or jumper circuit on circuit boards (PCBs) to meet specific layout requirements of the circuit. Although ideally, the resistance value of a jumper resistor should be zero, in reality, due to manufacturing limitations, all resistor components will have a certain resistance value, including a 0 ohm resistor.diode

The resistance of a jumper resistor is very small, usually in the milliohm (m Ω) range. They are widely used in the manufacturing of electronic products, allowing designers to design circuit layouts more flexibly without adding additional wires. In addition, jumper resistors can also be used to replace the originally planned placement of other components on printed circuit boards. The advantage of doing so is to maintain consistency in circuit board design while leaving room for future upgrades or modifications.diode
