In tape, but not machine ready. To have a leader and trailer added ( 25 charge), use Pri Sec I in R V T out code letter C instead. (1 turn) (100 turns) D = 13 machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2500 parts per full reel). 3 1 2. Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc. 3. Maximum volt-time product is for the secondary, based on 2000 Gauss. 4. Primary current of 20 A causes less than 25C temperature rise from 25C ambient. Higher current causes a greater temperature rise (see Temperature Rise vs Current curve). 5. Terminating resistance (R ) value is based on 1 Volt output with 20 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. 6 Electrical specifications at 25C. Refer to Doc 362 Soldering Surface Mount Components before soldering. Specifications subject to change without notice.
