HXX40 1.5uH Y0331R503050 Power Inductor for Antminer Hashboard

HXX40 1.5µH Y0331R503050 Plug-In Power Inductor | 26.85×23mm for Antminer Hashboard

The HXX40 1.5µH plug-in power inductor (part number Y0331R503050) is a high-current through-hole power inductor used on Antminer hashboards as the output inductor on the buck-converter stages that feed the hashing ASICs. With its compact 26.85×23mm footprint and a 1.5µH inductance sized for the high-frequency switching converters typical of ASIC hashboard rails, the part is a direct drop-in replacement when the original inductor on the hashboard has failed.

Hashboard inductors live a hard life: continuous high-current load, elevated PCB temperature, and constant magnetic flux cycling at the buck switching frequency. When an inductor fails — usually from winding insulation breakdown or core saturation under sustained overcurrent — the hashboard rail collapses and the downstream ASIC chain drops off. Replacing the inductor with a fresh HXX40 Y0331R503050 restores the rail and brings the hashboard back to spec.

When You Need to Replace the HXX40 Inductor

• Hashboard rail voltage low — buck converter switching but output droops under load.
• Visible damage on the inductor — discolored windings, burnt insulation, cracked core.
• Continuity check fails — measure resistance across the inductor leads; should read very low DCR (a few milliohms).
• Hashboard intermittent crashes traced to power-rail instability on a specific buck-converter stage.
• Repair-bench restock for hashboard rebuilds with known-failing inductor positions.

FAQ — HXX40 1.5µH Power Inductor

Q: How do I confirm the inductor is the failed part?
A: Power off the hashboard and measure resistance across the inductor leads — a healthy power inductor reads a few milliohms (essentially zero on most multimeters). An open inductor reads OL. If the resistance is significantly elevated or the inductor is visibly damaged (discoloration, cracked core), replace it.

Q: Can I substitute a different 1.5µH inductor?
A: Verify three things match: physical footprint (26.85×23mm), inductance (1.5µH), and current rating (must match or exceed the original). The HXX40 is specifically rated for ASIC hashboard duty — a low-current 1.5µH part will saturate and overheat.

Q: Rework profile for plug-in through-hole inductors?
A: Through-hole rework — desolder both leads with a vacuum desoldering pump or solder wick, lift the part out, clean the holes, install the fresh inductor with leads through the original pads, solder both leads, trim excess. No specific orientation needed.

Q: Which Antminer models use this inductor?
A: The HXX40 Y0331R503050 is used across multiple Antminer hashboard generations as a buck-output inductor. Confirm the specific model by checking the inductor's silk marking on your hashboard before ordering.
