Aside from it being a scummy company, it’s not even a good price! For the same price, you can get name-brand resistors from Digikey for example. |

You're not seriously thinking about using umpteen resistors in parallel here..... |

If you're lucky, you'll find one with 1%, which is already very accurate for a current clamp, but costs much more than a current shunt, which is even more accurate. --- End quote --- Finding <1% accurate current clamps is not difficult, it is just that finding accurate AND cheap wont happen. ;D Hioki CT6846A 1000A current clamp is 0.2% accurate but about 3000 usd/eur :P |
| Martin72:
That's clear... There is one more question, which is: How exactly does it have to be and why? |
| BillyO:
Yeah, we know practically nothing about the use case. |
