The term CT designates a center tapped winding. OCL: Open Circuit Inductance, measured 20 KHz, 100 mV. L Sec: Leakage Inductance measured across the primary with the respective secondary winding short circuited. L C : Winding capacitance, formed by the primary and secondary wire. These wires form the Plates of this W/W capacitor. Measured at 100 KHz, 20 mV. CD Pri: This is the distributed capacitance. DCR: This is the resistance of the windings when measured in DC conditions. I : The maximum specified unbalanced DC current capability of the device. DC 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). U.S.A: TEL 619 674 8100 EUROPE: TEL 44 1483 401700 ASIA: TEL 886 7 821 3141 WEB:
