High-Current Inductor HPC1050-22uH 220 SMD

HPC1050-22uH SMD High-Current Inductor (Silkscreen 220) for Crypto Miner PCBA Repair

The HPC1050-22uH is a high-current SMD power inductor with a silkscreen marking of 220 (where 22 × 10⁰ uH = 22uH). Designed for high-current operation in demanding environments, it is the kind of choke fitted to crypto-miner hashboards, control boards and power supplies, where it provides energy storage for buck-converter rails and filter chokes for the PSU output stage.

Specifications

Where the HPC1050-22uH fits in mining hardware

22uH is one of the most common values used in buck-converter rails on crypto-miner control boards and PSU low-voltage stages. The HPC1050 series provides shielded magnetic construction and a compact SMD footprint, which keeps EMI low and saves board area — both critical on densely populated mining PCBA. Failed inductors typically present as charring on the package, audible buzzing under load, or a downstream DC rail that sags below specification.

Compatibility

Use as a replacement for shielded 22uH SMD power inductors marked 220 on the silkscreen. Multiple physical sizes ship under similar marking conventions — share the dimensions of the part you need before ordering, as instructed in the product specifications panel.

Common failure symptoms

• Visible burn mark or charring on a shielded inductor on the PSU or control board
• Audible buzzing from the inductor under load — saturation indication
• One DC rail measures low or oscillates with a scope after the inductor stage
• Heat-stressed solder joints around the inductor pads with adjacent components running hot
• Open-circuit reading across the inductor terminals after a thermal event

Frequently asked questions

How do I read the 220 silkscreen?

The first two digits are the significant figures (22) and the third is the multiplier as a power of ten (×10⁰). So 220 = 22 × 1 = 22uH. Do not confuse 220 with 220uH — for 220uH the silkscreen would normally read 221.

What size do you ship by default?

The HPC1050 family ships in several physical sizes. Send the dimensions of the failed inductor before ordering — we will confirm the size and lead time before fulfilling.

Can I use it on a hash board domain converter?

Some hash boards use 22uH inductors on the auxiliary or gate-drive supplies; ASIC domain converters typically use sub-µH parts. Match the value on the silkscreen of the failed inductor before ordering.

Do you stock matching values like 100uH (silkscreen 101) or 4.7uH (silkscreen 4R7)?

Yes — the HPC1050 100uH (silkscreen 101) is in stock; contact us for other values and physical sizes.
