The CSNL Series of SMD metal element chip resistors are now available in 1206, and 2010 sizes as well as the previous 2512 size. In addition, the CSNL 2, which is the 2512 size, has an improved resistance value range down to 0.5 milliohms and up to 10 milliohms. This 100% RoHS compliant product series is available in 1% or 5% tolerances and with a TCR of 50 ppm.
This expansion greatly improves our existing current sensing chip resistor in that the CSNL can now be used for higher power or high current designs. These higher power and higher current designs are rapidly increasing. The higher the current or power supplied, the lower the resistance value must be to avoid significant power loss during the sensing, thereby reducing the efficiency of the power circuit itself.
