Fixed Inductors Procurement Notes
Verify the specific suffix code to confirm the tolerance rating, as ordering specifications require explicit tolerance designation. Confirm that the 0603 package dimensions align with the target PCB footprint. Ensure the 15 mA rated current meets the circuit requirements to prevent saturation or thermal issues during operation.
Fixed Inductors Selection Notes
Select this component when a compact 0603 form factor is required for low-current RF or general-purpose applications. The 3.9 µH value suits specific impedance matching or filtering needs. Consider the 1.7 Ω DC resistance impact on voltage drop and the 15 mA current limit for power handling capabilities in the final design.
Fixed Inductors Part Context
This part belongs to the CTML0603F series of multi-layer chip inductors manufactured by Central Technologies. The series offers a wide range of inductance values from 47 nH to 2200 nH, utilizing ferrite cores for stable performance.
