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.\u003c\/p\u003e\n\u003ch3\u003eWhen You Need to Replace the HXX40 Inductor\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHashboard rail voltage low\u003c\/strong\u003e — buck converter switching but output droops under load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVisible damage\u003c\/strong\u003e on the inductor — discolored windings, burnt insulation, cracked core.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuity check fails\u003c\/strong\u003e — measure resistance across the inductor leads; should read very low DCR (a few milliohms).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHashboard intermittent crashes\u003c\/strong\u003e traced to power-rail instability on a specific buck-converter stage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRepair-bench restock\u003c\/strong\u003e for hashboard rebuilds with known-failing inductor positions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecs and Technical Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number Y0331R503050\u003c\/strong\u003e — encodes inductance and current rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInductance 1.5µH\u003c\/strong\u003e — sized for high-frequency buck-converter operation on hashboard rails.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e26.85 × 23mm physical size\u003c\/strong\u003e — direct drop-in for the Antminer hashboard inductor footprint.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug-in through-hole construction\u003c\/strong\u003e — robust mechanical bond, easy rework vs SMD.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-current rating\u003c\/strong\u003e — supports the continuous load on ASIC hashboard buck output stages.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHash board application\u003c\/strong\u003e — Antminer hashboard buck-converter output inductor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew condition\u003c\/strong\u003e — fresh stock with 3-day lead time on standard orders.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eHXX40 Y0331R503050 Power Inductor Specifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eY0331R503050\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003ePlug-In (Through-Hole) Power Inductor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInductance\u003c\/td\u003e\n\u003ctd\u003e1.5µH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhysical Size\u003c\/td\u003e\n\u003ctd\u003e26.85×23mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eThrough-hole\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eAntminer hashboard buck-converter output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLead Time\u003c\/td\u003e\n\u003ctd\u003e3 days (standard orders)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eFAQ — HXX40 1.5µH Power Inductor\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I confirm the inductor is the failed part?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I substitute a different 1.5µH inductor?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Rework profile for plug-in through-hole inductors?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Which Antminer models use this inductor?\u003c\/strong\u003e\u003cbr\u003eA: The HXX40 Y0331R503050 is used across multiple Antminer hashboard generations as a buck-output inductor.
