Tnisesm dual run capacitor 50+5 uF

The dual-run layout brings the compressor and fan connections together in one circular CBB65 capacitor, which can make a like-for-like replacement easier to identify when the existing unit uses the same rating and terminal labels. Its three top terminals are marked for the compressor, fan and common line, and the package includes 6.3 mm spade terminals for wiring. It is described for AC motor run, fan start or condenser applications, but those uses alone do not confirm a match for a particular system. Check the rating and connection layout on the existing capacitor before deciding.

Best use cases

This capacitor is aimed at applications where a dual-run unit is required for both the compressor motor and the fan. The labelled connections—Herm or H, Fan or F, and C—give a clear reference when comparing the terminal arrangement with the component being replaced. For instance, when servicing a condenser, you can compare the markings on the old capacitor with the new one before reconnecting the compressor and fan leads. The supplied spade terminals may be useful if the wiring needs compatible 6.3 mm connectors.

It suits you if your equipment calls for a 50+5 uF dual-run capacitor and its wiring matches these labels. If your repair calls for separate capacitors, a different rating or another terminal arrangement, this is a different approach and may not be the right replacement. Is a familiar set of labels enough to establish compatibility? No: the rating and the appliance or motor requirements still need to line up.

Product specs

• Type: CBB65 dual-run capacitor
• Capacitance: 50+5 uF
• Tolerance: ±6%
• Operating temperature: -40°C to +70°C / -104°F to +158°F
• Terminals: Three top terminals marked Herm/H, Fan/F and C
• Included: One capacitor and 9 6.3 mm spade terminals

According to the manufacturer, the Herm/H terminal is for the compressor motor, Fan/F is for the fan, and C is the common line. Treat those markings as connection references rather than a substitute for confirming the wiring on your equipment. The supplied connectors are a practical extra, though the listing does not specify installation instructions or whether they suit every existing lead.

Where it shines

The main draw is the combined compressor-and-fan format: rather than sourcing two separate components, buyers replacing a matching dual-run capacitor can compare one unit’s rating and terminal markings with the original. That can make the selection process more straightforward when the existing part is clearly labelled. The circular CBB65 form and included spade terminals also give useful details to compare during a replacement.

The limitation is that the product information does not name specific compatible equipment or provide dimensions. A 50+5 uF rating and matching labels are important checks, but they do not establish fit for every AC motor, fan or condenser. If the old capacitor’s rating is unclear, or its connections differ, pause and confirm the required part before ordering. It isn't for you if you need a capacitor with another capacitance or cannot verify that your equipment uses this dual-run arrangement.

Final decision

This Tnisesm capacitor is worth considering for a like-for-like replacement when the existing component is a 50+5 uF dual-run model with the same compressor, fan and common connections. The included 6.3 mm terminals may save a separate connector search, but they do not resolve a mismatch in rating or wiring. Choose this format when those details agree, look for a different replacement when the equipment requires another specification or a separate run-capacitor setup.
