CT1008CSF-102J

Fixed Inductors Overview

The CT1008CSF-102J is a surface-mount wirewound inductor manufactured by Central Technologies. It features a ceramic core and offers a nominal inductance of 1 µH with a ±5% tolerance. The component has a maximum DC resistance of 1.8 Ω and a rated current of 0.65 A. It operates within a temperature range of -40 °C to 125 °C and exhibits a self-resonant frequency of 350 MHz.

Fixed Inductors Feature Summary

• Wirewound construction on a ceramic core for stable RF performance
• Surface-mount chip design suitable for automated assembly
• High Q-factor measurement at 350 MHz ensures efficient signal handling

Fixed Inductors Applications

• RF filter circuits
• General purpose inductive applications
• Signal processing components

Fixed Inductors Procurement Notes

Verify the specific suffix 'F' indicates RoHS compliance and lead-free status, as standard CT1008CS variants are explicitly noted as non-compliant and leaded. Confirm the manufacturer's official datasheet for the exact package dimensions and terminal configuration to ensure compatibility with the target PCB footprint. Cross-reference the part number against the latest Central Technologies catalog to validate availability and any potential revisions to the electrical specifications or testing frequencies.

Fixed Inductors Selection Notes

Select this component when a 1 µH inductance value is required with tight ±5% tolerance for precision RF applications. The wirewound architecture provides higher Q-factors compared to general-purpose types, making it suitable for filtering tasks. Ensure the operating environment stays within the specified -40 °C to 125 °C range. The 1.8 Ω DC resistance and 0.65 A current rating must align with the circuit's power dissipation and load requirements to prevent saturation or overheating.

Fixed Inductors Part Context

This part belongs to the CT1008CS series of SMD ceramic core inductors from Central Technologies. While the base CT1008CS line includes non-RoHS compliant variants, the CT1008CSF designation specifically denotes a lead-free, RoHS-compliant version. The series covers a wide inductance range, typically from 3.9 nH to 10,000 nH, serving various general-purpose and RF needs in compact surface-mount form factors.

Fixed Inductors Replacement Considerations

Direct substitutes include other 1 µH ±5% SMD wirewound inductors in similar footprints, such as the CT1008CSF-102K if tolerance flexibility is acceptable. Verify that alternative parts match the 1.8 Ω max DCR and 0.65 A current rating. Ensure the replacement also meets RoHS standards if environmental compliance is mandatory for the assembly process.
