DUAL TERMINATOR RESISTOR VALUES – Schematic 5
Standard CTS Dual Terminator products contain 2[N-2] resistors of two different values with resistor value connected to a common buss. The part
number includes the EIA Code value of the Thevenin equivalent resistances of R
1
and R
2
. 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.]
