Passive Electric Components

Explore the collection of run and start capacitors at F.W. Webb. A capacitor, also known as a condenser, stores electrical energy with the terminals inside joined together by metal plates. Use our convenient filters to sort the capacitors by size, material, voltage, and capacitance. Browse top-quality run and start capacitors from trusted makers, including Mars, Source 1, Copeland, and Diversitech, to find the best fit for the motor.

Frequently Asked Questions

Are capacitors DC or AC?

Capacitors are both DC and AC; in DC, a capacitor is an open switch, while in AC circuits, it offers a leading current.

Is a battery a capacitor?

No, a battery isn't a capacitor; they operate differently. A battery is a device that stores chemical energy converted into electric energy, while a capacitor is a component that stores electric energy in a field.

What are the advantages of capacitors?

Capacitors have the following advantages:

  • Boost voltage
  • Reduce current to allow for more capacity
  • Lessen losses
  • Offer more power when the motor needs it
