When ordering, please specify packaging code: Typical Circuit CU8965-ALC 4 1 Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic tape (600 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ( 25 charge). Pri Sec I I R V in out T out (1 turn) (100 turns) B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C. 3 2 + D = 13 machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2500 parts per full reel). 2. Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc. 3. For specific questions regarding frequency range, please contact us at cst coilcraft.com. 4. Volt-time product is for the secondary, between pin 1 and 2. 5. 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). 6. Terminating resistance (RT) value is based on 1 Volt output with 20 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: RT = Vout Nsec / Iin. 7 Electrical specifications at 25C.
