Fixed Inductors Procurement Notes

Verify that the specific part number suffix matches the required tolerance code, as ordering specifications require explicit tolerance designation. Confirm lead-free status and RoHS compliance requirements against project constraints. Ensure the 0402 package dimensions align with the target PCB layout. Cross-reference the manufacturer's latest datasheet to confirm active status and availability before finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 3.9 nH is required in a compact 0402 form factor. The ceramic core construction supports operation up to 125 °C, suitable for demanding thermal environments. The 0.76 A current rating makes it appropriate for power delivery paths or RF stages requiring moderate current handling without excessive saturation.

Fixed Inductors Part Context

This part belongs to the CT0402CSF series of wire-wound chip inductors from Central Technologies. The series offers various inductance values ranging from 1.6 nH to 390 nH in the 0402 package. These components are designed for surface mount assembly and provide reliable performance for general purpose and RF applications.

Fixed Inductors Replacement Considerations

Compatible substitutes include other 0402 ceramic-core wire-wound inductors with 3.9 nH nominal inductance and ±5% tolerance. Verify that replacement parts match the 0.08 Ω DC resistance and 0.76 A current rating to ensure circuit continuity.
