Caddock CD2520FC Series

  • Caddock

Product Features

  • Low resistance precision flip-chip surface-mount resistor
  • Utilises the proven Caddock Micronox® resistance films to achieve the unique low resistance range
  • Pedestal terminal design helps maintain precision and its copper core provides heat spreading which enhances the high power handling capabilities
  • Chip size of 2520
  • Bare ceramic back surface
  • Inductance of less than 5nH typical
  • Maximum chip temperature of +150°C
  • Operating temperature range of -55°C to +150°C



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).
