Fixed Inductors Procurement Notes
Verify the exact part number against official Central Technologies documentation to confirm specifications. Ensure that the required inductance, current rating, and physical dimensions align with the design constraints. Cross-reference datasheets for any updates on compliance or mechanical changes before finalizing procurement decisions.
Fixed Inductors Selection Notes
Select this component when an unshielded wirewound inductor with 330 µH inductance is required in an 1812 package. Consider the 85 mA current limit and 14 Ohm DC resistance during circuit design. Verify that the 4 MHz self-resonant frequency meets the operational bandwidth requirements of the target application.
Fixed Inductors Part Context
This inductor belongs to the CTMC1812F series of molded chip inductors produced by Central Technologies. The series includes various inductance values within the same physical footprint, allowing for standardized board layouts across different circuit designs while maintaining consistent mechanical integration.
Fixed Inductors Replacement Considerations
The CTMC1812SF-271J is a documented alternative within the same series, offering 270 µH inductance. Designers must verify if the reduced inductance value and similar electrical characteristics are acceptable for the specific circuit function.
