Frequently Asked Questions

Q: What inductance range does this adjustable ferrite core inductor cover?

A: This 26T adjustable ferrite core inductor covers a tunable inductance range of 1µH to 6.3µH. You can dial in the exact value you need by adjusting the ferrite screw core, making it versatile for a wide variety of high-frequency circuit applications.

Q: What types of circuits and projects are these inductors suitable for?

A: These inductors are well-suited for high-frequency applications such as RF circuit design, AM/FM radio tuners, oscillator circuits, bandpass filters, and switching power supplies. Their adjustable core makes them especially useful during the prototyping and tuning stages of a project.

Q: How many inductors come in a pack, and how do I adjust the inductance value?

A: Each order includes 10 inductors. To adjust the inductance, use a non-metallic trimmer tool (ferrite core adjustment tool) to carefully turn the ferrite screw core. Turning the core in increases inductance toward 6.3µH; turning it out decreases inductance toward 1µH. Always use a proper non-metallic tool to avoid cracking the core.

Q: Why choose a ferrite core inductor over an air-core inductor for high-frequency work?

A: Ferrite core inductors offer higher inductance values in a smaller package compared to air-core designs. The ferrite material efficiently concentrates the magnetic field, reducing core losses at high frequencies and providing a stable, tunable inductance — advantages that make them a popular choice in RF and switching circuit design.
