Frequently Asked Questions (FAQs)

What is a ferrite‑bead power inductor?

+
It is a high‑current inductor that uses ferrite material to suppress high‑frequency noise while maintaining stable inductance and efficiency.

How do ferrite‑bead inductors differ from flat‑wire inductors?

+
Ferrite‑bead inductors focus on EMI suppression and stable inductance, while flat‑wire inductors emphasize reduced AC resistance and higher current density.

What current ratings are available in the IN Series ferrite‑bead inductors?

+
Depending on the part number, saturation current ratings range from ~20 A up to 70 A.

What inductance values are offered in this series?

+
The IN Series ferrite‑bead inductors cover a wide range, from tens of nanohenries (nH) to several microhenries (µH).

How do these inductors perform thermally?

+
They are designed for continuous operation up to 125 °C, with stable inductance under heavy load conditions.

Are shielded versions available?

+
Yes, shielded models are available to reduce EMI, alongside unshielded options for cost and size efficiency.

What package sizes are offered?

+
Compact SMT footprints range from ~7 mm up to ~15 mm, with low‑profile options for space‑constrained designs.

What applications are these inductors best suited for?

+
They are ideal for CPU/GPU VRM/VRD stages, point‑of‑load converters, servers, telecom systems, and networking equipment.

How does low DCR benefit performance?

+
Low DC resistance minimizes conduction losses, improving efficiency in high‑current designs.

Are these inductors RoHS compliant?

+
Yes, all IN Series SMT ferrite‑bead inductors are manufactured to meet RoHS environmental compliance standards.
