Fixed Inductors Procurement Notes

Verify the specific tolerance code suffix 'G' corresponds to the required ±2% accuracy during ordering. Confirm that the package dimensions and terminal configuration match the target PCB layout. Ensure the operating environment remains within the specified -40 °C to 125 °C range to maintain performance integrity. Cross-reference the datasheet for the exact DC resistance and current ratings relevant to the specific application load.

Fixed Inductors Selection Notes

Select this component when a 4.7 µH inductance value with tight ±2% tolerance is required for high-frequency applications. Consider the 0.26 A current rating and 4 Ω DC resistance limits for power handling requirements. The 1008 package size offers a balance between footprint constraints and electrical performance. Verify compatibility with the target circuit's impedance and frequency range against the 390 MHz self-resonant frequency specification.

Fixed Inductors Part Context

This part belongs to the CT1008CSF series of SMD wirewound chip inductors manufactured by Central Technologies. The series provides values ranging from 3.9 nH to 10,000 nH. The 'G' suffix indicates a ±2% tolerance, distinguishing it from standard tolerance variants. The product line is engineered for reliable performance in general-purpose and RF applications using ceramic core technology.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include CT1008CSF-472J (±5%) or CT1008CSF-472K (±10%), provided the tolerance relaxation is acceptable. Other manufacturers offering 1008 package 4.7 µH ceramic core inductors may be considered if electrical parameters align. Verify pinout and thermal characteristics before substitution.
