OCL (primary inductance) is measured at the primary winding. Turns ratio is specified primary: Octal SMT IC Mfr. IC Part Number Comments secondary. STD Temp EXT Temp B. To make a 1CT:1 ratio from a 1CT:2CT ratio, use only one-half of the secondary (2CT) winding. C. It is possible to use the same transformer model for the three impedance levels of T1 (100 W) and CEPT Mindspeed BT8510 T1/E1 T1071NL - (75 & 120 ). For specific connection information and resistor values, refer to IC vendors data (Conexant) BT8510 T1/E1 T1071NL - book. D. Dual Ratio Transformer (T1071NL and T1145NL) - These transformers have tapped secondary windings CN8380 T1124NL T1114NL to provide two turns ratios (T/R).

Extended Temperature Range Models - For extended temperature range transformers (-40C to +85C (Siemens) operating temperature range), OCL (Open Circuit Inductance) for the primary winding) is specified PEB2256 3.3 V E1/T1/J1 T1142NL T1231NL at both -40C and +25C. At -40C, OCL is 600 H minimum. All other parameters are specified at +25 C Intel LXT 300/301 T1065NL T1105NL only. Standard temperature range is 0C to +70C.
