1. 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.

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.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
