1. When ordering, please specify termination and packaging coded:
B0727-BLD
Termination: L =RoHS tin-silver over tin over nickel over phos bronze.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Packaging:D
=13″ machine-ready reel. EIA-481 embossed plastic tape
(175 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 D instead.
2. Inductance measured at 10 kHz, 0.1 Vrms, 0 Adc with windings connected in series.
3. Leakage inductance measured at 100 kHz, 0.1 Vrms, 0 Adc from pins 1 to 5 with
pins 4 and 2 connected and all chip side pins shorted.
4. Capacitance measured at 100 kHz, 0.1 Vrms, 0 Adc from chip side to line side.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
