Other common HPC1050 values in the same family: 220 = 22 µH (sold separately as HPC1050-22uH), 100 = 10 µH (HPC1050-10uH). Match the silkscreen on the PCB exactly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I test the inductor in-circuit?\u003c\/strong\u003e\u003cbr\u003eA: Power off, DMM in low-ohm mode. A healthy 1µH inductor reads near 0Ω (winding resistance is sub-100mΩ). An open winding reads OL — replace. For shorted turns, an LCR meter at 100kHz–1MHz is required; if the measurement is well below 1µH, the inductor has shorted turns and must be replaced.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Always check the upstream MOSFET when this fails?\u003c\/strong\u003e\u003cbr\u003eA: Strongly recommended. The most common cause of a blown HPC1050 inductor is a shorted MOSFET driving DC through the winding. Replace the inductor and the MOSFET together — skipping the MOSFET inspection is a common cause of repeat failure within minutes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Bulk pricing for repair benches?\u003c\/strong\u003e\u003cbr\u003eA: Yes — email contact@lys-sz.com for reel-quantity pricing on HPC1050 family inductors.\u003c\/p\u003e\n\u003ch3\u003eRelated products\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/inductor-hpc1050-10uh-smd-hashboard-repair\"\u003eHPC1050-10µH SMD Inductor (100 silkscreen)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/high-current-inductor-220-silkscreen-hpc1050-22uh-smd-for-pcba-power-board-and-psu-maintenance\"\u003eHPC1050-22µH SMD Inductor (220 silkscreen)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/1r80-smd-1206-high-quality-resistor-antminer-s19-s19xp-hashboard\"\u003e1R80 SMD 1206 Resistor (Antminer S19 \/ S19 XP)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/l3-s9-boost-module-14v-for-hashboard-l3-s9-6r8-rt8537-green-version-voltage-regulator\"\u003eL3+\/S9 Boost Module 6R8 RT8537\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eHashboard \/ PSU repair benches stocking HPC1050-1uH inductors by the reel?
