1 When ordering, please specify packaging code: e.g.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 (2500 parts per full reel).
2 Inductance measured between secondary at 100 kHz, 0.1 Vrms, 0 Adc.
3 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Maximum volt-time product for the secondary, based on 2000 gauss.
5 Primary current of 20 A causes approximately 25°C temperature rise above 25°C ambient (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 (Ohms) = Vout × Nsec / Iin.
7 Ambient temperature range: −40°C to +125°C
8 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +165°C (ambient + temp rise)
10 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
11 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
