1 When ordering, please specify packaging code:
e.g. HPX2126LD
Packaging: D = 13" machine-ready reel
EIA RS-481 plastic tape (300 parts per full reel).
B = Less than full reel
In tape, not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead.
2 Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc.
3 DCR is for each winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Isolation is measured from primary to secondary of each transformer.
5 Current flowing through each secondary that causes a 20°C temperature rise from 25°C ambient
6 Ambient temperature: −40°C to +85°C.
7 Storage temperature: Component: −40°C to +85°C
Tape and reel packaging: −40°C to +80°C
8 Electrical specifications at 25°C.
9 Refer to Soldering Coilcraft Components before soldering.
1 When ordering, please specify packaging code: e.g. HPF2187LC
Packaging: C = 7" machine-ready reel
EIA RS-481 plastic tape (500 parts per full reel).
B = Less than full reel
In tape, not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead.
D = 13" machine-ready reel
EIA RS-481 plastic tape. Not stocked, factory order only (2000 parts per full reel).
