High Current Inductor 101 Silkscreen HPC1050-100uH SMD

HPC1050-100uH SMD High-Current Inductor (Silkscreen 101) for Crypto Miner PCBA Repair

The HPC1050-100uH is a shielded SMD high-current power inductor with a silkscreen marking of 101 (where 10 × 10¹ uH = 100uH). Designed for high-density installation with low buzzer noise and high anti-interference capability, it supports switching frequencies up to 3MHz and operating temperatures up to 125°C — characteristics that fit the buck converter, filter and PSU output stages found across crypto-miner hashboards, control boards and power supplies.

Specifications

Where the HPC1050-100uH fits in mining hardware

Shielded high-current inductors are used wherever a power converter needs both energy storage and EMI containment in a compact footprint. On crypto-miner boards that means filter chokes at the PSU output, common-mode storage for low-side gate-drive supplies on hash boards, and tightly-packed local converter rails on control boards. The HPC1050's 3MHz frequency capability and 125°C rating cover modern high-switching-frequency designs.

Compatibility

Use as a replacement for shielded 100uH SMD power inductors marked 101 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 hash board
• Audible buzzing from the inductor under load (saturation indication)
• One DC rail measures low or oscillates with a scope after the inductor
• Heat-stressed solder joints around the inductor pads with adjacent components running hot
• Open-circuit reading across the inductor terminals after thermal event

Frequently asked questions

How do I read the 101 silkscreen?

The first two digits are the significant figures (10) and the third is the multiplier as a power of ten (×10¹). So 101 = 10 × 10 = 100uH.

What size do you ship by default?

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

Is the magnetic shielding important?

Yes. Shielded inductors contain the magnetic field and reduce EMI coupling into nearby high-impedance signals — important on hash boards where ASIC communication lines run close to the converter stages.

Can it operate at high frequencies?

Yes, the HPC1050 is rated for switching frequencies up to 3MHz, suitable for modern DC-DC converter designs.
