(2) when leads connected in parallel, dcr is half the value. when lead connected in series, dcr is twice the value (3) isat current is the saturation current at which inductance rolls off approximately 30% from its initial (zero dc) value. (4) irms equals dc current, that causes component to increase by approximately 40c from 25c ambient. (5) irated current is the rated current at which inductance rolls off approximately 10% from its initial (zero dc) value. general note tt electronics reserves the right to make changes in product specifcaton without notce or liability. all inf ormaton is subject to tt electronics own dat a and is consider ed accura te at tme of going to print. ? tt electronics plc http://www.ttelectronics.com/magnetics/customer-service-enquiry rev. 03 8.17 bi technologies a-1445, jalan tanjung api 25050 kuantan pahang darul makmur malaysia ph: +60 9 565 8888 fax: +60 9 514 3555
