Current Sense Resistor Networks

The 1787 current sense resistor network series from Caddock offers 3 or 4 resistance values in a single through-hole package, ranging from R_A = 99.9Ω, R_B = 9.9Ω and R_C = 0.9Ω up to R_A = 1kΩ, R_B = 100Ω, R_C = 10Ω and R_D = 1Ω. Caddock offers 12 standard models of the 1787 series with 5 network arrangements, providing the specific accuracy and resistance values required for a wide range of current measuring instruments and circuits. They can offer maximum power ratings of up to 0.75W or 1W depending on the model.

• Through-hole current sensing resistor network
• 12 standard models in 5 network arrangements
