1000µF 16V Aluminum Electrolytic Capacitor for Antminer Hashboard / Bitmain PSU
This 1000µF 16VDC aluminum electrolytic capacitor in a 10x12.5mm radial can is the high-capacitance, low-ESR filter cap used on Antminer hashboards and Bitmain power supply boards. It absorbs ripple on the bulk 12V rail, supports peak-current transients drawn by the ASIC chain and stabilises the buck regulators feeding the domain rails.
With a 5000-hour lifetime, -55°C to +105°C operating range and ±20% tolerance, it's built for the continuous duty cycle of a 24/7 mining deployment. Failed 1000µF/16V caps are one of the most common findings on a hashboard rework — replacing them brings the rail back to clean DC.

Where the 1000µF 16V cap sits in the design
On Antminer hashboards, the 10x12.5mm 1000µF/16V can sits on the input side of the buck regulators that step the 12V (or 14.5V) rail down to the ASIC domain voltage. On Bitmain PSU output boards, it's used as the bulk output filter cap. Its job is to absorb the high-frequency switching ripple from the regulators while supporting peak current draw without rail collapse.
Compatibility
Replacement cap for the 1000µF/16V 10x12.5mm radial slot on Antminer hashboards and Bitmain PSU output sections. Confirm can diameter, lead pitch and silkscreen value before ordering. Pair with the 47µF/63V hashboard cap and the 330µF/35V PSU cap on full rework jobs.
Common failure symptoms
- Capacitor visibly bulged, vented or showing brown electrolyte residue at the base
- ESR meter reads well above the rated low-ESR class
- Hashboard domain rail noisy under load, chips dropping out under stress
- Buck regulator running hot or shutting down on input-cap ripple feedback
- PSU output rail showing 100kHz+ ripple downstream of a tired filter cap
Frequently asked questions
Is this the same cap on Antminer hashboard and PSU positions?
Yes — the 1000µF/16V 10x12.5mm radial part is shared across many Antminer hashboard input slots and Bitmain PSU output filter positions.
What ESR class is supplied?
Low-ESR series, suitable for switching-converter input / output filtering at typical mining domain ripple frequencies.
Can I substitute 1500µF or 2200µF?
You can move up in value if the 10x12.5mm can fits the footprint, but staying at 1000µF preserves the original filter response.
What other PSU / hashboard caps do you stock?
The 47µF/63V hashboard cap, 220µF/25V APW3 cap, 330µF/35V APW9 cap and the 450V/270µF bulk cap are all available alongside this 1000µF/16V part.
