Fixed Inductors Procurement Notes

Verify the specific suffix 'SF' against the manufacturer's latest datasheet to confirm lead-free status and RoHS compliance details. Ensure the ordering code matches the required tolerance and packaging configuration. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a compact surface-mount inductor with moderate current handling is required. The 1812 package offers a balance between size and power dissipation. Consider the 520 mA rated current limit and 360 mOhm resistance for thermal management. Verify that the unshielded nature does not interfere with nearby sensitive components due to potential magnetic field emission.

Fixed Inductors Part Context

This part belongs to the CTMC series of wirewound chip inductors from Central Technologies. The series includes various inductance values and package sizes, such as the CTMC1210 and CTMC1812F variants. The CTMC1812SF-R56K specifically denotes the 1812 form factor with a 560 nH value, fitting within the broader family of molded or drum-core passive components.

Fixed Inductors Replacement Considerations

Direct substitutes include other 1812 package inductors with similar 560 nH inductance and current ratings. Check for equivalent DC resistance and Q-factor specifications. Alternative manufacturers may offer shielded versions if EMI suppression is critical, though magnetic characteristics will differ.
