The CBB61 2-wire 3µF capacitor is designed as a run capacitor for single-phase AC motors, providing phase shift support to ensure smooth and continuous motor operation.
Instead of focusing only on fan replacement, this capacitor is engineered for long-term electrical stability in compact motor systems operating under 50/60Hz AC power.
Design Concept & Performance Focus
⚙️ Electrical Function Oriented Design
This capacitor is optimized to maintain stable motor torque during continuous operation, helping reduce speed fluctuation, overheating, and efficiency loss caused by aged or unstable capacitors.
🔧 Simple 2-Wire Structure
The two-lead configuration allows direct integration into standard motor circuits without complex wiring, making it suitable for both OEM assembly and after-sales maintenance.
🔥 Reliable Insulation & Safety
Encapsulated with flame-retardant plastic housing and metallized polypropylene film, the capacitor delivers strong insulation resistance and dependable self-healing performance during long operating cycles.

Typical Use Cases:
Rather than limiting to ceiling fans, this CBB61 capacitor is suitable for:
Single-phase AC motor run circuits
Ventilation and air circulation equipment
Small household motorized appliances
Maintenance replacement for aging motor capacitors
It helps restore normal motor operation when symptoms such as slow start, weak torque, or unstable running speed appear.
⭐Replacement & Maintenance
This 5µF capacitor is ideal for fan maintenance and part replacement, ensuring correct motor run behavior. Before installation, match the capacitance and voltage rating with the original component to maintain proper fan performance.
