When ordering, please specify packaging code: Typical Circuit SCS-200LD Packaging: D = 13 machine-ready reel. EIA-481 embossed plastic tape (200 parts per full reel). B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ( 25 charge), use code letter C instead. 2. Inductance measured between secondary pins at 10 kHz, 0.06 Vrms, 0 Adc. 3. Primary DCR is measured with the windings connected in parallel. 4. Maximum volt-time product is for the secondary, based on 2000 Gauss. 5. Primary current of 30 A causes less than 25C temperature rise from 25C ambient. Higher current causes a greater temperature rise (see Temperature Rise vs Current curve). 6. Terminating resistance (R ) value is based on 1 Volt output with 30 Amps T flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: R = V N / I T out sec in. 7. Electrical specifications at 25C. Refer to Doc 362 Soldering Surface Mount Components before soldering. Specifications subject to change without notice.
