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.

Req=R1R2/(R1 + R2)

Examples:

753095131A R1=220 Ohms R2=330 Ohms Req=132 Ohms

753095191A R1=330 Ohms R2=470 Ohms Req=194 Ohms

753095131C R1=180 Ohms R2=470 Ohms Req=130 Ohms

Pin #1 is common to R2 and Pin N is common to R.
