Tnisesm Pump Start Capacitor 105-126 µF
Product description
A pump that struggles to start can point to a capacitor that needs replacing. This Tnisesm motor start capacitor is intended for AC motor starting circuits, including pump and pool-pump applications.
It has a 105-126 µF rating and a 250 V rated voltage. Matching those details to the part being replaced matters more than choosing by appearance alone.
Without having tested it, the useful decision points are its electrical ratings, size and quick-connect terminals. The listing does not identify specific pump models.
Technical details
The stated capacitance is 105-126 µF (also listed as MFD), with a rated voltage of 250 V and a frequency rating of 50/60 Hz. Its listed dimensions are 1.41 × 2.76 inches (36 × 70 mm), and it uses a 1/4-inch standard quick-connect terminal.
The shell is described as phenolic (bakelite) and ABS. These construction details may help when comparing the replacement with an existing part, but they do not confirm compatibility with a particular motor. The listing gives no model-specific fit information or installation instructions.
Compatibility and requirements
This is designed for AC motor starting circuits, with pumps and pool pumps named as examples. It is not presented as a general-purpose capacitor for every appliance or motor. Before choosing it, compare the old capacitor’s capacitance and voltage ratings, along with its physical dimensions and terminal style. A mismatch in any of those details could make it unsuitable for the intended replacement.
It’s a good option if your application uses a 105-126 µF start capacitor rated at 250 V and the listed connections and size match the part you need. It won’t suit you if you need a different capacitance or voltage, or if your motor requires a different terminal arrangement.
Usage tips
Treat this as a replacement component, not a diagnosis for every pump that fails to start. First identify the capacitor specification required for your motor and compare it with the ratings printed on the existing part. Also check that the available space can accommodate the listed 36 × 70 mm size and that the quick-connect terminals correspond to your setup.
For example, when comparing a removed pump capacitor with this listing, check the rating, then the body dimensions and terminal type before proceeding. The product description calls the terminals easy to use and replace, but it does not provide step-by-step installation guidance. If you are unsure about working with the motor’s electrical components, seek qualified help rather than relying on the product listing alone.
Three specific questions
Is this listed for pool pumps? Yes. Pool pumps are named among the intended applications, alongside other pump and AC motor starting circuits.
What frequency and voltage are specified? The listing states 50/60 Hz and a rated voltage of 250 V.
What connection does it use? It has a 1/4-inch standard quick-connect terminal. Confirm that this matches the part being replaced.
Before you buy
The main trade-off is that the listing provides useful electrical and physical specifications but no named motor or pump models. That makes it a more targeted choice than buying a generic component by appearance, while offering less certainty than a replacement explicitly matched to your equipment model. Choose it when the ratings, dimensions and terminals align with your existing part, if any of those details differ or are unknown, this listing alone is not enough to establish a fit.
