With their high power density, the devices can be used instead of larger high power components or multiple lower power devices. This reduces board space requirements and placement costs, while enabling smaller and lighter end products. In addition, RCWK0306 series resistors provide higher reliability than larger thick film devices by reducing the coefficient of thermal expansion (CTE) mismatch with the PCB, thereby lowering solder joint stress.
The resistors’ four-terminal Kelvin connection enables greater measurement accuracy with extremely low resistance values from 0.01-0.1Ω, and tolerance of 1%. RoHS-compliant and halogen-free, the devices feature a metal glaze thick film on high quality ceramic. They are optimised as current sensing resistors in DC/DC converters, voltage regulation modules, and inverters in mobile phones, computers, air conditioners, and heat pumps.
