Fixed Inductors Procurement Notes

Verify the specific datasheet version from Central Technologies to confirm RoHS compliance status and exact pinout configurations. Ensure that the 27 mA rated current and 217 ohm DC resistance parameters align with the thermal requirements of the target application environment before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when high inductance values are required in an axial form factor. Consider the 217 ohm DC resistance impact on power dissipation, which is approximately 158 mW at rated current. Verify that the 370 kHz self-resonant frequency meets the operational bandwidth needs of the circuit design.

Fixed Inductors Part Context

This part belongs to the CTS4HTF series of shielded axial inductors from Central Technologies. The series offers various inductance values tailored for general-purpose electronic applications. The CTS4HTF-473J specifically provides a 47 mH value, distinguishing it from lower inductance variants like the CTS4HTF-6R8J within the same product family.

Fixed Inductors Replacement Considerations

Cross-reference with other axial shielded inductors offering 47 mH ±5% tolerance. Verify that substitute components match the 217 ohm DCR limit and 27 mA current rating to ensure equivalent performance in switching regulator or filtering applications.
