When ordering, please specify packaging code: Typical Circuit CST2010-200LD 11 2 + Packaging: D = 13 machine-ready reel. EIA-481 embossed plastic tape (300 parts per full reel). B = Less than full reel. In an effort to simplify our part Pri Sec numbering system, Coilcraft is eliminating the need I I in out R V T out (1 turn) (N turns) for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D. 2. Inductance measured between secondary pins at 1 kHz, 0.1 Vrms, 0 Adc. 3. For specific questions regarding frequency range, please contact us at 12 4 cst coilcraft.com. 4. Volt-time product is for the secondary, between pin 2 and 4. 5. Primary current of 47 A causes approximately 40C 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 40 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.
