The CC2520WB low resistance precision wire-bondable surface-mount resistor series from Caddock offers resistance values from as low as 0.025Ω up to 10Ω making it ideal for current sensing applications. The CC2520WB series features low inductance of 5nH (typical) which provides excellent high frequency and pulse response, with high pulse handling and overload capabilities. The WB variant of the CC series from Caddock is a hybrid mountable version with metallised pads for wire-bonding utilising aluminium wire and a metallised back surface for solder attachment of the back surface to a heat sinking substrate.
