Dual Terminator Overview
Standard CTS Dual Terminator products contain (2N-2) resistors of two different values with each resistor
value connected to a common buss. The part number includes the EIA Code value of the Thevenin equivalent
resistances of R1 and R2. The Thevenin equivalent resistance is calculated in the following way: The suffix
letter relates only to the sequence of variations that equal the same equivalent resistance. Reference chart.
