1 When ordering, please specify termination code: e.g. B0570-BL
  Termination: L = RoHS compliant tin-silver over tin over copper.
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
2 Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc
3 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Leakage inductance measured at 100 kHz, 0.1 Vrms.
5 Isolation tested between primary and secondary and between primary and auxiliary windings for one minute.
6 Ambient temperature range: −40°C to +85°C
7 Storage temperature range: Component: −40°C to +85°C
Packaging trays: −40°C to +80°C
8 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.
