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. 4 Isolation is measured from primary to secondary of each transformer. 5 Ambient temperature: –40°C to +85°C. 6 Storage temperature: Component: –40°C to +85°C Packaging: –55°C to +80°C 7 Electrical specifications at 25°C. 8 Refer to Soldering Coilcraft Components before soldering.

1 When ordering, please specify packaging code: e.g. HPX2187LC 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). 2 Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc. 3 DCR is for each winding. 4 Ambient temperature: –40°C to +85°C. 5 Storage temperature: Component: –55°C to +85°C Packaging: –55°C to +80°C 6 Electrical specifications at 25°C. 7 Refer to Soldering Coilcraft Components before soldering.
