• Mobile phones
• Computers and printers

Fixed Inductors Procurement Notes

Verify the specific ordering suffix to confirm the tolerance code, as variations exist within the series. Ensure the procurement documentation explicitly states RoHS compliance and lead-free status, as these are critical for regulatory adherence. Confirm the package dimensions match the required PCB footprint before finalizing orders.

Fixed Inductors Selection Notes

Select this component when a compact 0603 form factor is required for RF filtering or energy storage. The 270 nH value and 900 MHz self-resonant frequency suit high-frequency circuits. Consider the 170 mA current rating and 2.3 Ω DC resistance to ensure compatibility with the target circuit's power budget and impedance requirements.

Fixed Inductors Part Context

This part belongs to the CT0603CSF series of general-purpose wire-wound inductors manufactured by Central Technologies. The series offers various inductance values ranging from low nanohenries to hundreds of nanohenries, all sharing the same 0603 surface-mount footprint and ceramic core construction for consistent mechanical integration.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 270 nH inductance, 0603 package size, and similar current ratings. Verify that alternative components maintain comparable self-resonant frequency and DC resistance characteristics to ensure circuit performance parity.
