The CD2015WBA low resistance precision wire-bondable surface-mount resistor series from Caddock offer resistance values from as low as 0.01Ω up to 0.2Ω making them ideal for current sensing applications. The CD2015WBA series features a unique pedestal terminal design for surface-mount applications as well as low inductance of 5nH (typical) which provides excellent high frequency and pulse response, with high pulse handling and overload capabilities. The WBA variant of the CD series from Caddock is a hybrid mountable version with Copper pedestal terminals and an aluminium surface layer for wire-bonding utilising aluminium wire and a metallised back surface for solder attachment of the back surface to a heat sinking substrate.
