When ordering, please specify packaging code: CST2010-200LD Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape (300 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 D instead. 2. Inductance measured between secondary pins at 1 kHz, 0.1 Vrms, 0 Adc. 3. Maximum volt-time product is for the secondary, based on 2000 Gauss. 4. Primary current of 40 A causes less than 25°C temperature rise from 25°C ambient. Higher current causes a greater temperature rise (see Temperature Rise vs Current curve). 5. Terminating resistance (RT) value is based on 1 Volt output with 40 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: RT = Vout × Nsec / Iin. 6 Electrical specifications at 25°C.
