The component has a maximum DC resistance of 2.8 Ohms and a saturation current rating of 290 mA. It utilizes a nonstandard package size measuring 10.10 mm by 10.10 mm. The device is RoHS compliant and lead-free, designed for general-purpose applications requiring high inductance values.

Fixed Inductors Feature Summary

• Shielded construction to minimize electromagnetic interference
• Surface-mount design for automated assembly
• RoHS compliant and lead-free manufacturing

Fixed Inductors Applications

• General-purpose power supply filtering
• DC-DC converter input or output stages
• Signal processing circuits requiring high inductance

Fixed Inductors Procurement Notes

Verify the suffix 'TF' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the specific package dimensions match the target PCB footprint, noting the nonstandard 10.10mm x 10.10mm size. Ensure the application current does not exceed the 290 mA saturation rating to maintain inductance stability. Cross-reference the datasheet revision date for any updates to electrical characteristics.

Fixed Inductors Selection Notes

Select this component when a high inductance value of 1000 µH is required in a compact surface-mount form factor. Consider the 2.8 Ohm DC resistance for efficiency calculations in low-current applications. The shielded design makes it suitable for environments sensitive to magnetic field leakage. Evaluate the 290 mA saturation limit against peak load currents to prevent performance degradation.

Fixed Inductors Part Context

This part belongs to the CTSLF1045 series of shielded power inductors from Central Technologies. The series offers various inductance values ranging from microhenries to millihenries. The '1045' designation refers to the case size, while '102M' specifies the 1000 µH inductance value. The 'T' suffix typically denotes tape-and-reel packaging availability.

Fixed Inductors Replacement Considerations

Direct substitutes include other parts within the CTSLF1045 series with equivalent inductance and current ratings. Generic replacements must match the 10.10mm x 10.10mm footprint and shielded construction. Verify that alternative components meet the same RoHS compliance standards and have comparable saturation current capabilities.
