1 When ordering, please specify termination code: e.g. HA4060-AL
  Termination: L = RoHS compliant tin-silver over tin over nickel over phos bronze
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 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B impedance analyzer or equivalent.
3 Ipk: Peak primary current drawn at minimum input voltage.
4 DCR is at 25°C with the windings connected in parallel. For other operating temperatures, use this DCR at Temperature calculator.
5 Leakage inductance is for both windings of the primary with the secondary windings shorted.
6 Turns ratios are with the primary and secondary windings connected in parallel.
7 Ambient temperature range: −40°C to +85°C
8 Storage temperature range: Component: −40°C to +85°C
Packaging trays: −40°C to +80°C
9 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.
