10 Best Ac Capacitor 2025 in the United States

The BlueStars 270-324 µF 250 VAC Round Motor Start Capacitor comes as a pack of two, making it a convenient choice if you need replacements for electric motors. Its capacitance range of 270-324 microfarads and voltage rating up to 250 volts AC fit well within typical specifications for motor start capacitors, ensuring compatibility with many applications. The round shape and compact size (46mm x 86mm) allow for easy installation in tight spaces. It operates safely within a temperature range from -40°C to 65°C, covering most household and light industrial environments.

The capacitor is made from durable bakelite material and is designed with a 10,000 AFC anti-explosion pressure switch, adding a layer of safety and reliability. BlueStars claims OEM-level quality and long-lasting performance, with low internal power loss which can help motors start smoothly and efficiently. Another benefit is the lifetime protection warranty, offering peace of mind against defects.

One thing to keep in mind is the tolerance of ±20%, which means the actual capacitance can vary somewhat from the stated value; this is common but something to check if your motor requires precise specs. Also, while it replaces many well-known capacitor models, confirming exact compatibility with your motor model before buying is advisable. If you need a reliable, safe, and reasonably priced start capacitor for typical AC motors, this product fits the bill nicely, especially if you want a pair for backup or multiple repairs.

The BlueStars 108-130 µF start capacitor is designed for single-phase electric motors, providing a good match for those needing a reliable replacement with a voltage rating of 110-125 VAC. Its capacitance range of 108-130 µF and ±20% tolerance suits many motor start applications, especially in residential or light industrial use. The round shape and compact size (36mm x 70mm) allow it to fit easily into standard motor housings.

It handles temperatures between -40℃ and +65℃, which covers most typical operating environments but might be less ideal for extreme heat situations. Made from high-quality bakelite, this capacitor promises durability and stability over time, with low power loss and no harmful PCBs, which is good for safety and environmental concerns. Another plus is the 10,000 AFC anti-explosion safety feature, which adds peace of mind during operation.

Its tolerance of ±20% is fairly standard but not very tight, so slight variations in performance can be expected. Also, since it’s made in China, some users might be cautious about quality consistency, although the brand claims to meet OEM standards and offers a lifetime protection warranty. This capacitor is suitable for those looking for a budget-friendly, dependable start capacitor that fits many common motor models, but if very precise specs or high-temperature resilience are required, other options might be preferred.

The BlueStars 108-130 µF start capacitor is designed for single-phase electric motors, making it a solid choice for replacing motor start capacitors in appliances like air conditioners, pool pumps, or general motors. Its capacitance of 108-130 µF and voltage rating of 220-250V fit well within common motor specifications, supporting reliable motor startup. The round shape and compact size (36mm x 70mm) allow it to fit into many motor housings easily.

It operates safely across a wide temperature range from -40°C up to 65°C, suitable for various environments. This capacitor meets strict US and Australian safety standards, including UL and TÜV certifications, which add confidence in its quality and explosion protection features. The ±20% capacitance tolerance is typical for this kind of capacitor but means the exact capacitance might vary somewhat, which usually is not a problem for most motor applications.

Made by BlueStars, a reputable brand, it comes with lifetime protection, so you have support if any defects occur. Although it is manufactured in China, which for some buyers might raise concerns about consistency, the certifications help mitigate this. If you need a dependable, easy-to-install start capacitor for common motor repairs, this product offers good value and safety.
