CD54 4.7UH 4R7 High Power SMD Inductor for Whatsminer CB4 V10 Control Board

CD54 4.7µH 4R7 High-Power SMD Inductor – Whatsminer CB4 V10

The CD54 4.7 µH (4R7) high-power SMD inductor is the buck-stage inductor on the Whatsminer CB4 V10 control board. Compact 5 × 5 × 4 mm footprint with superior energy storage and low DCR — built for high-current switching duty in the control-board DC-DC rails.

High-saturation design and excellent heat resistance make the inductor a robust replacement when the original burns out from a downstream short or sustained overcurrent. The wire-wound shielded structure keeps EMI in check while supporting clean voltage regulation under load.

Typical Use Cases

• Buck-stage inductor replacement — failed switching inductor on CB4 V10.
• DC-DC rail recovery — restore housekeeping voltage after a fault event.
• Production refurbishment — bulk inductor stock for CB4 V10 rebuild lines.
• Bench inventory — common-failure SMD component for ASIC control-board repair.

FAQ — CD54 4.7µH Inductor

Q: How to spot a failed inductor?
A: Visible burn marks, cracked ferrite, or discoloration on the package. Electrically: open-circuit reading or shorted to ground (windings melted through insulation).

Q: Substitution with CD43 / CD75 same value?
A: Possible if the new package fits the footprint and current rating matches. CD54 is the OEM size for CB4 V10 — match for like-for-like repair.

Q: Bulk pricing?
A: Yes — email contact@lys-sz.com.
