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.

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.
