## Description

The round aluminium-case CBB65 measures 60 mm in diameter and 90 mm high, combining 40 µF and 5 µF capacitance ratings in one dual-run capacitor. Its two ratings serve separate motor circuits, making it a practical replacement format for compatible air conditioners, heat pumps and other HVAC equipment.

With clearly marked HERM, FAN and C terminals, it provides a straightforward reference for matching the compressor, fan and common connections during service. Confirm the capacitance and voltage required by the equipment before selecting a replacement, and follow appropriate precautions: capacitors can retain electrical energy even when the system is switched off.

## Getting the most from it

This capacitor brings two motor-run capacitances into a single round case: 40 µF for one circuit and 5 µF for the other. In a typical HVAC application, those connections serve the compressor and fan motors. That combined format is useful when replacing a compatible dual-run capacitor, rather than assembling separate capacitors for the two circuits.

The terminal markings help identify where each circuit connects: HERM for the compressor motor, FAN for the fan motor and C for the common line. During replacement, the existing wire positions provide a practical reference, but the equipment’s required ratings and wiring must remain the deciding factors. If the unit has been showing symptoms such as a fan that will not start, unusual noise or intermittent cooling, a capacitor replacement may be part of the HVAC service process.

## Why it makes sense

A dual-run design keeps both capacitance values in one component, which suits equipment that uses separate fan and compressor motor circuits. The 40+5 µF rating identifies the two values, while the stated ±6% capacitance tolerance gives a specific figure for matching the replacement part to the system. The round case measures 6 cm wide and 9 cm high, a useful size reference when checking the available mounting space.

Compared with using individual capacitors for each circuit, a dual-run unit consolidates the two functions in one case. For a compatible air conditioner or heat pump, that means one replacement component with labelled connection points. It is also listed for condenser straight-cool systems, motors, compressors and pumps that call for the same electrical specifications.

## What to clarify

**What does 40+5 µF mean?** It combines two capacitance values in one case. In the described HVAC arrangement, the connections serve the compressor and fan motors respectively.

**What do the terminal labels mean?** HERM connects to the compressor motor, FAN to the fan motor and C to the common line. Use the equipment’s wiring arrangement and required specifications when identifying connections.

**Which voltage rating should replace an existing capacitor?** The product is described with 370 or 440 Vac ratings. The manufacturer states that a 370 Vac capacitor can be replaced by a 440 Vac one, but a 440 Vac capacitor must not be replaced by a 370 Vac one. Capacitors may retain charge after power is off, so handling and discharge require appropriate safety precautions, discharge is a standard measure for HVAC professionals.

## When it makes sense

Choose this YukiHalu capacitor when an air conditioner, heat pump or other compatible system calls for a 40+5 µF CBB65 dual-run replacement. Its combined ratings, compact round case and labelled terminals make it a relevant option for service work on equipment with separate compressor and fan circuits. Matching the system’s capacitance, voltage and connections keeps the replacement aligned with the application.
