CD32 2.2UH 2R2 SMD Inductor: The Reliable Solution for Whatsminer CB4-V10 Control Board Repairs
Repair your Whatsminer CB4-V10 control board with the dependable CD32 2.2UH 2R2 SMD Inductor. Engineered to provide a reliable and efficient solution, this powerful inductor is the key to getting your control board back in operation.
High-Quality CD32 2.2UH 2R2 SMD Inductor for Improved Control Board Performance
The CD32 2.2UH 2R2 SMD Inductor, also known as a power inductor, high current inductor, or surface mount high power inductor, may be small in size (33.52mm), but it delivers a substantial punch. With its high energy storage capacity, low resistance, and exceptional performance, this inductor is specifically designed to restore and enhance the performance of your Whatsminer cryptominer motherboard.

Where the CD32-2R2M fits on a Whatsminer control board
On the Whatsminer CB4-V10 control board, small CD32-class inductors are paired with PWM controllers to generate the local 1.0V / 1.2V / 1.8V / 3.3V rails that power the CPU SoC, the memory, the boot flash and the network PHY. When one of these rails sags or oscillates, the BMC reboots randomly, the miner loses pool connection, or the hash board chain fails to enumerate at startup.
Compatibility
Use the CD32-2R2M as a direct replacement for failed or burnt 2R2-marked SMD inductors on Whatsminer CB4-V10 control boards. Verify the silkscreen marking (2R2 = 2.2uH) on the original component before fitting; the same footprint is used by other inductance values across the CD32 family.
Common failure symptoms
- Control board boots intermittently or hangs partway through Linux init
- SSH / web interface drops out under thermal stress
- Hash board chain fails to enumerate or shows missing ASICs at startup
- Visible burn mark on a small SMD inductor near a buck converter IC
- One local DC-DC rail measures low or oscillating with a scope
Frequently asked questions
How do I read the 2R2 marking?
The 2R2 silkscreen translates to 2.2 with the R acting as a decimal point — so 2R2 = 2.2uH. The CD32 series uses similar codes for other values (e.g. 4R7 = 4.7uH).
Is this the same inductor used on Whatsminer M30S / M30S+ control boards?
The CB4-V10 control board is shared across multiple Whatsminer M-series models. Confirm the marking on the failed part before substituting — different rails on the same board use different inductance values.
What current rating do I need?
The CD32-2R2M handles up to 1.60A DC. If the rail it serves draws more current, a larger CD-series inductor or a different package may be the correct choice — share a photo of the burnt part for confirmation.
