1. When ordering, please specify turns ratio and packaging codes:
Dimensions are in
HTX7045-184ARC
Turns ratio: A = 1:1 C = 1:2
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (350 parts per full reel). Quantities less than full
reel available: in tape (not machine ready) or with
leader and trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (1500 parts per
full reel).
2. Inductance measured at 100 KHz, 0.1 Vrms, 0 Adc
3. Leakage inductance measured at 100 kHz, 0.1 Vrms with secondary
pins shorted.
4. 2800 Vrms, 4000 VDC; one minute isolation (hipot) measured between
primary and secondary.
5. Capacitance measured from pin 1 to pin 3, 250 KHz, 0.1 Vrms.
6. Insulation level may be Functional, Basic, or Reinforced depending on
application variables such as working voltage, pollution degree, OVC,
and altitude. Please contact Coilcraft for full details.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
