Definition of Terms
Ratio: This is the turns ratio, expressed as “Primary:Secondary”. The term “CT” designates a center tapped winding.
OCL:
L
C
CD Pri: This is the distributed capacitance.
DCR:
The minimum primary inductance and the maximum distributed capacitance satisfy the transmitter output and receiver
input impedance requirements of CCITT I.430 for both TE and NT.
The maximum distributed capacitance allows sufficient margin for the capacitance of the IC and a protection diode
network. It is consistent with the overall maximum value specified and permitted length of the basic access TE cord.
Flammability – Materials used in the products are recognized UL94-VO. Products meet the requirements of
IEC 695-2-2 (needle flame test).
