To meet high current and very low resistance requirements, the Bourns® Model CSM2F series has resistance values as low as 50 milliohms (μΩ), continuous current up to 1000 A, and power ratings up to 50 W. To increase design flexibility, new elements The device is available in three different package sizes: 8518, 7036, and 6918 metrics. These high-power current-sense resistors also provide extremely low resistance drift and temperature, with low resistance over a temperature range of 20°C to 60°C. The temperature coefficient (TCR) is 50 PPM / °C.
Compared with other technologies, current-sense resistors are becoming more and more popular due to their high measurement accuracy and relatively low cost. By measuring the voltage of the component, the current flowing through the component can be obtained by using Ohm's law conversion. Current-sense resistor It has become the best solution for most market applications, especially for battery management systems in automotive, industrial and electronic calculator designs.
The Bourns® CSM2F series consists of three series: CSM2F-8518 series, CSM2F-7036 series and CSM2F-6918 series. All products in the whole series are available and RoHS compliant*.
