Caddock CD2520FC Series

The CD2520FC low resistance precision flip-chip surface-mount resistor series from Caddock offers resistance values from as low as 0.01Ω up to 0.2Ω making it ideal for current sensing applications. The CD2520FC 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. For general applications, the CD2520FC series has a power rating of 1.5W (at +70°C).
