What is the resistance value of a 0Ω resistor? How much current can a 0Ω resistor pass? [Copy link]

How much current can a 0Ω resistor carry? This question must have been asked by every hardware engineer. And there is another related question, which is how big the resistance of a 0Ω resistor is?

These two questions are simple, and the answers should be clear, but netizens gave different answers. Some said 0Ω resistance is 50mΩ, while others said it is only 20mΩ; some said it can only pass 1A current, while others said it can pass 1.5A...

Can you guys come and explain your doubts and share your understanding and opinions? ? ?

The actual resistance of a general 0 ohm resistor is around 50 milliohms with a deviation of 5%.
So based on the rated power, you can calculate its rated current.
Take 0402 1/16W as an example: 1/16=I*I*0.05, that is, I=1.118A
Take 0603 1/8W as an example: 1/8=I*I*0.05, that is, I=1.58A
Take 0805 1/4W as an example: 1/4=I*I*0.05, that is, I=2.236A

Current, or power, is closely related to packaging and brand

The most reliable way is to look for the device manual.

There is no such thing as 0 ohms in the world

Is the correspondence between your package and power incorrect?

Using UWB for wireless positioning can meet the needs of future wireless positioning and has considerable advantages among many wireless positioning technologies. Juheng High-Tech's actual application cases show that the accuracy of ultra-wideband positioning can reach 10cm. In addition, ultra-wideband radio positioning can easily combine positioning with communication. The rapid development of short-range ultra-wideband communication will undoubtedly drive the development of UWB in positioning technology, which is difficult for conventional radio to do. With the continuous maturity and development of UWB ultra-wideband positioning technology and the continuous increase in market demand, it is believed that ultra-wideband positioning systems will be applied to more industries.
