A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The nominal resistance at 25°C is typically between 0.001 mΩ and 0.1 mΩ, depending on the model. The exact value should be confirmed with the manufacturer.
The resistance tolerance is ±0.1%, which ensures high accuracy in current measurement. This is a standard specification, but always verify with the datasheet.
The maximum continuous current capacity is between 10 A and 100 A, depending on the model and power rating. For higher currents, a lower resistance value may be required.
The temperature coefficient is between ±15 and ±50 ppm/°C, meaning the resistance changes slightly with temperature. This is important for applications with varying temperatures.
