When ordering, please specify **packaging** code: | **CU8965-ALC** - **Packaging: C** = 7″ machine-ready reel. EIA-481 embossed plastic tape (600 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. - **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. ## **Typical Circuit** **==> picture [203 x 70] intentionally omitted <==** **----- Start of picture text -----**<br> 4 2<br>Iin (1 turn)Pri (100 turns)Sec RT Vout<br>3 1<br>**----- End of picture text -----**<br> 3. Maximum volt-time product is for the secondary, based on 2000 Gauss. 4. Primary current of 20 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 20 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: RT = Vout × Nsec/ I in. - 6 Electrical specifications at 25°C.
