Electrical specifications at 25ºC. Operating temperature range: -40ºC to +130ºC. Meets UL 94V-0. To determine the terminating resistor use the following formula to determine Rb. Eo=Ip(Rb/TR) Eo - output voltage Ip - primary current Rb - terminating resistor TR - turns ratio Add designator to end of p/n C = Center Tap Secondary N = Non-Center Tap Secondary Specifications subject to change without notice. 800.729.2099 tel www.icecomponents.com 86 (02/08) CT03-1
