Notes
- When ordering, please specify testing code: e.g. ST448RFT474BLZ.
- Inductance is for each winding, measured at test frequency using a Voltech AT3600 or equivalent.
- Current that causes a 20°C temperature rise from 25°C ambient.
- DCR is specified per winding.
Termination:
- L= RoHS compliant matte tin over nickel over phos-bronze
Testing:
- Z = Unscreened
- H = Group A screening per Coilcraft CP-SA-10001
Custom screening also available.
