10 Best Ac Capacitor 2025 in the United States

The VEXUNGA 45/5 uF 370/440V Dual Run Start Capacitor is designed for air conditioning units, heat pumps, and condensers. It features a dual run start, meaning it can replace both 370V and 440V capacitors, making it versatile for various applications. With a capacitance of 45/5 microfarads, it fits standard needs for many AC units.

The round shape and compact size (2.36 inches in diameter and 3.35 inches in height) make it easy to install in tight spaces. The operating temperature range from -40℃ to +70℃ ensures reliability in extreme conditions, and its compliance with US standards like EIA-456-A and UL listings speaks to its quality and safety.

The polypropylene material adds durability, and it has a safety rating of 10,000 AFC (Available Fault Current), which is a plus for safety-conscious users. However, the 6% tolerance in capacitance might be a consideration for those needing highly precise specifications. Brand reputation is solid, but as with any component, ensuring compatibility with your specific AC model is crucial. This capacitor is a good choice for those looking for a reliable, versatile, and durable component for their AC units.

The VEXUNGA 7.5uF 370/440VAC capacitor is designed for air conditioner units, pool pumps, and air condensers. It offers a capacitance of 7.5 microfarads and supports both 370V and 440V, making it versatile for different AC units. The capacitor is an oval shape, measuring 2.17 x 2.17 x 2.03 inches and weighs 3.21 ounces. Made of polypropylene and aluminum, it promises durability and reliability.

With an operating temperature range from -40℃ to +70℃, it can withstand various environmental conditions. Being compliant with stringent US standards and UL & CUL listed ensures it meets high safety and quality benchmarks. This capacitor is especially suitable for those looking to replace capacitors like the 27L566 and others mentioned in its compatibility list.

The VEXUNGA capacitor stands out for its flexibility, safety compliance, and durability, making it a solid choice for those in need of a reliable AC capacitor.

The Okumoe 45+5 uF 370V/440V CBB65 Dual Run Round Start AC Capacitor is a solid choice for those needing a reliable component for AC motor start, fan start, heat pumps, and condenser straight cool units. With a capacitance of 45+5 µF and an operating voltage of up to 440V, it meets most standard requirements for such applications. Its dual run functionality and clear labeling on the terminals (HERM, FAN, and C) simplify installation and use.

The compact round shape (2.36 inch diameter and 3.94 inch height) makes it easy to fit in various units. One of the standout features is its wide operating temperature range of -40℉ to +158℉, ensuring it performs well in both cold and hot environments. Additionally, the lifelong free replacement service is a significant advantage, offering peace of mind regarding durability and customer support.

Potential buyers should note that the product is manufactured in China, which might be a consideration for those preferring locally made products or specific quality standards. The brand Okumoe is relatively new in the market (first available October 2023), so long-term reliability is yet to be fully established. Nonetheless, the initial build quality and customer support commitment make it a worthwhile option for most AC system needs.
