BOJACK 45+5µF Dual Run/Start CBB65 Capacitor 370VAC Metal Shell, Triple-Terminal for HVAC Motors

BOJACK 45+5µF CBB65 dual run circular start capacitor is a compact, metal-shelled unit that combines a 45µF run capacitor and a 5µF start capacitor into one 370VAC-rated part for compressors and condenser fans.

This dual-capacitor design consolidates two functions into a single component, saving space and simplifying replacement in central air-conditioners, heat pumps, and other 50/60Hz AC motor systems. Built with metallized polypropylene film and a sturdy metal housing, the BOJACK CBB65 is engineered for continuous motor run and intermittent start duties over a wide temperature range. The top-mounted triple-terminal layout marked H (Herm), F (Fan), and C (Common) matches common HVAC wiring schemes for quick swap-ins.

How does this capacitor fit into HVAC and motor systems?

The CBB65 replaces separate run and start capacitors by providing dedicated terminals for compressor (Herm), fan, and common. Its 370V AC rating and dual capacitance values are tuned for typical residential and light-commercial compressors and fan motors operating at 50/60Hz.

• Three labeled terminals: H (compressor), F (fan), C (common) for straightforward wiring.
• Dual values: 45µF run plus 5µF start integrated in one housing.
• Rated 370V AC suitable for standard HVAC line voltages.
• Direct replacement for several OEM numbers (e.g., 97F9895, Z97F995).

What size and environmental conditions does it tolerate?

The metal-shelled capacitor measures about 50 mm in diameter and 95 mm tall, making it small enough for tight control boxes while still offering robust construction. It performs across a wide temperature range, resisting heat and built to safety standards that help reduce explosion risk under overload.

• Compact dimensions: Ø50 mm × 95 mm height for confined enclosures.
• Operating range: -40°C to +70°C for cold-start and hot-climate use.
• Safety rating: 10,000 AFC for enhanced fault tolerance.
• Durable metallized polypropylene dielectric for stable electrical performance.

How reliable and safe is the BOJACK CBB65 capacitor?

The CBB65 uses metallized polypropylene film, a common dielectric in motor capacitors for predictable aging and low loss. The metal shell and high fault-current rating improve mechanical protection and help meet HVAC equipment safety expectations when installed correctly.

• Dielectric: metallized polypropylene film for long-life operation.
• Tolerance: ±6% to maintain motor timing and torque within design limits.
• Metal housing provides impact resistance and heat dissipation.
• Safety-designed for motor start/run duties with rated AFC protection.

Who is this product for? Technicians, maintenance teams, and DIY HVAC enthusiasts who need a compact, reliable replacement capacitor for central air-conditioners, heat pumps, condensers, and motors will find the BOJACK CBB65 suited to many retrofit and repair jobs. It is especially useful where control-box space is limited or where combining run and start functions into a single component speeds installation. Always verify compatibility with your unit’s wiring and ratings before replacing capacitors, and follow safety procedures for working on energized equipment.
