Voltage Rating (V)
With the 370V/440VAC rating, it handled the demanding workload with grace.
Brand and Quality
The BOJACK capacitor truly saved the day by bringing my AC back to life during the hottest week of the year.

The BOJACK 45+5 uF 370V/440V CBB65 Dual Run Circular Start Capacitor is a versatile option that can be used for AC motor run, fan start, or condenser applications. With a capacitance of 45+5 µF and a voltage rating of 370V/440VAC, this capacitor is designed to handle a range of applications. The dual run feature is beneficial for those needing a start and run capacitor in one, simplifying installation and reducing the need for multiple components.

Its round shape and relatively compact size (65 mm diameter and 95 mm height) make it suitable for various installations without taking up much space. The capacitor is made from polypropylene, which is known for its durability and reliability. Additionally, it operates efficiently within a wide temperature range of -40℃ to +70℃, making it suitable for various environmental conditions. The safety rating of 10,000 AFC adds an extra layer of reliability and security.

The ±6% tolerance might be a bit high for applications needing very precise capacitance values. While BOJACK is a decent brand, it may not be as well-known or trusted as some other leading brands in the market. This could be a factor for users looking for the highest quality components. This capacitor is a good choice for general AC motor, fan, and condenser applications, offering a good balance of performance and versatility at a reasonable price.

BOJACK 40+5 uF 40/5 MFD ±6% 370V/440 VAC CBB65 Dual run circular start capacitor for AC motor run or fan start or condenser straight

The BOJACK 40+5 uF Dual Run Circular Start Capacitor is designed for use in AC motors, fan starts, and condensers. It offers a capacitance of 40+5 microfarads (µF) with a tolerance of ±6%, which ensures it can handle variations in power demand effectively. The voltage rating of 370V/440V makes it versatile for various AC applications, while its round shape and compact dimensions (2.36 inches in diameter and 3.55 inches in height) allow for easy installation in tight spaces.

Operating efficiently in a wide temperature range from -40℃ to +70℃ (-104℉ to +158℉), this capacitor is suitable for different environmental conditions. The safety rating of 10,000 AFC adds a layer of reliability, making it a safe choice for continuous use. The three terminals labeled for compressor motor (Herm/H), fan (Fan/F), and common line (C) are clearly marked, which simplifies installation and reduces the risk of incorrect connections.

The product's main limitation is that it might not be suitable for applications requiring different capacitance values or non-round shapes. Additionally, while BOJACK is recognized for offering good quality, it is always advisable to verify compatibility with your specific AC unit's requirements.

Buying Guide for the Best Ac Capacitor

When choosing an AC capacitor, it's important to understand the role it plays in your air conditioning system. The capacitor stores and releases electrical energy to help start and run the compressor and fan motor. Selecting the right capacitor ensures your AC unit operates efficiently and reliably. Here are the key specifications to consider when picking an AC capacitor and how to navigate them to find the best fit for your needs.
Capacitance (µF)Capacitance, measured in microfarads (µF), indicates the amount of electrical charge the capacitor can store. This is crucial because the correct capacitance ensures your AC unit's motor starts and runs properly. Capacitors typically range from 5 µF to 80 µF. To choose the right capacitance, check the specifications of your AC unit or the old capacitor. Using a capacitor with the wrong capacitance can lead to inefficient operation or damage to the motor.
Voltage Rating (V)The voltage rating of a capacitor indicates the maximum voltage it can handle. This is important to ensure the capacitor can withstand the electrical load of your AC unit. Common voltage ratings are 370V and 440V. It's generally safe to use a capacitor with a higher voltage rating than required, but never use one with a lower rating. Check your AC unit's specifications or the old capacitor to determine the correct voltage rating.
Type (Run or Start)There are two main types of AC capacitors: run capacitors and start capacitors. Run capacitors are used to maintain a constant charge to the motor while it's running, while start capacitors provide a boost of energy to start the motor. Run capacitors are typically rated for continuous duty, while start capacitors are rated for short-term use. Determine which type your AC unit requires by consulting the unit's specifications or the old capacitor.
Shape and SizeAC capacitors come in various shapes and sizes, including round and oval. The physical size and shape are important to ensure the capacitor fits in the designated space within your AC unit. Measure the dimensions of the old capacitor or the space where it will be installed to ensure a proper fit. While the shape doesn't affect performance, it must match the space available in your unit.
Temperature RatingThe temperature rating of a capacitor indicates the range of temperatures it can safely operate within. This is important for ensuring reliable performance in different environmental conditions. Capacitors typically have a temperature rating of -40°C to +70°C or higher. Choose a capacitor with a temperature rating that matches or exceeds the conditions in which your AC unit will operate, especially if you live in an area with extreme temperatures.
Brand and QualityThe brand and quality of the capacitor can affect its reliability and lifespan. High-quality capacitors from reputable brands are more likely to provide consistent performance and last longer. Research different brands and read reviews to find a reliable capacitor. While it might be tempting to choose a cheaper option, investing in a high-quality capacitor can save you from future repairs and replacements.
