Understanding Start Capacitors: 161-193 MFD 250VAC

What is a Start Capacitor?

A start capacitor is a type of capacitor that is used to provide a temporary high voltage boost to start a motor or other electrical device. It is designed to store electrical energy and release it quickly to provide the necessary power to get the device running.

Start Capacitor Ratings: 161-193 MFD 250VAC

When it comes to start capacitors, the ratings are crucial to ensure safe and efficient operation. A 161-193 MFD 250VAC start capacitor is rated to provide a capacitance of 161 to 193 microfarads and can withstand a maximum voltage of 250 volts AC.

What Does MFD Stand For?

MFD stands for Microfarads, which is a unit of measurement for capacitance. In the context of start capacitors, MFD refers to the amount of electric charge that the capacitor can store.

How Does a Start Capacitor Work?

A start capacitor works by storing electrical energy when the motor or device is not in use. When the device is turned on, the capacitor quickly releases the stored energy to provide a high voltage boost to get the motor running. Once the motor is up to speed, the capacitor is disconnected from the circuit, and the motor runs on its own.

Characteristics of a 161-193 MFD 250VAC Start Capacitor

Here are some key characteristics of a 161-193 MFD 250VAC start capacitor:

  • High capacitance: The capacitor has a high capacitance rating, making it suitable for large motors or devices that require a lot of power to start.
  • High voltage rating: The capacitor can withstand a maximum voltage of 250VAC, making it suitable for use in industrial or commercial applications.
  • Long lifespan: Start capacitors are designed to last for a long time, with some lasting up to 10-15 years or more in ideal conditions.
  • Low equivalent series resistance (ESR): The capacitor has a low ESR, which means it can handle high currents without overheating.

Applications of a 161-193 MFD 250VAC Start Capacitor

A 161-193 MFD 250VAC start capacitor is commonly used in a variety of applications, including:

  • Air conditioners and refrigeration units
  • Pumps and compressors
  • Industrial machinery and equipment
  • Commercial HVAC systems


A 161-193 MFD 250VAC start capacitor is a crucial component in many electrical devices and systems. By understanding its ratings, characteristics, and applications, you can ensure safe and efficient operation of your device or system. Remember to always choose a start capacitor that meets the specific requirements of your application to ensure optimal performance and longevity.
