10 Pack TEMCo 50 uF Run Capacitor CBB65 370V - HVAC Motor Replacement

In this review of the 10 Pack TEMCo 50 uF Run Capacitor CBB65, the bottom line is straightforward: this kit is aimed at technicians and homeowners who need reliable, ready-to-install replacements for HVAC fans, blowers and motor-driven equipment. The reviewer found the strongest reason to buy is the combination of practical features - a 50 uF rating at 370 VAC, wide temperature range and a heavy duty aluminum casing - which together make these capacitors a dependable, value-oriented option for replacing OEM single and three phase motor capacitors.

Key Features

• 50 uF, 370 VAC: Provides the common run capacitance and voltage margin needed for many air conditioner and motor applications, reducing the chance of electrical mismatch.
• Wide temperature range: Rated from -40 C to +85 C so the capacitors tolerate both cold-starts and high ambient heat around motors and compressors.
• Durable construction: Housed in heavy duty aluminum with a steel cap to protect the internal metallized polypropylene film from mechanical damage and outdoor conditions.
• Safety and longevity features: PCB-free, 10,000 AFC protected and UL rated E335070 for added peace of mind in industrial and residential settings.
• Standard terminals and fit: 1/4in quick disconnect terminals and compact round shape make these units straightforward to install as OEM replacements.
• 5 year warranty: Offers a reasonable protection window against early failures for typical motor service applications.

Who It's For

This 10 pack is best for HVAC technicians, maintenance crews, and DIYers who service multiple units or want a supply of identical capacitors for pool pumps, air compressors, fans and blowers. The pack saves time sourcing parts and ensures consistent replacements across single and three phase motor systems.

Those who only need a single, custom-sized capacitor or require specialized low-profile or enclosure-specific units should look elsewhere. Also, if precise sizing or a nonstandard terminal layout is required, confirm dimensions and terminal type before buying.

Pros & Cons

Pros

• Reliable standard 50 uF, 370 VAC rating that fits many motor and HVAC applications.
• Robust materials and safety features such as metallized polypropylene film, PCB-free design, and UL rating.
• Good value and convenience when buying in a 10 pack for multiple repairs or replacements.
• Straightforward installation with 1/4in quick disconnect terminals and a common round form factor.

Cons

• Size is larger than some expect at about 1.95 in diameter and 4.8 in height, so check cabinet clearance before installation.
• Like all capacitors, lifespan can vary; some users report multi-year life while others experienced earlier failure.
