Cbb65 45uf±5% 450v SH

This CBB65 45μF±5% 450V SH capacitor is a core component that provides starting power and operational support for high-power home appliances such as air conditioners and washing machines. It acts like a reservoir, releasing a strong current at the moment the motor starts and maintaining a stable current during operation.

Core Features and Technical Specifications
Energy Storage Specifications (45μF ±5%): 45 microfarads is its rated capacitance, determining the amount of "thrust" it can provide to the motor. The ±5% error tolerance ensures that the equipment receives a stable starting torque even during voltage fluctuations, preventing motor humming or overheating due to unstable current.

Voltage Rating (450V AC): This is the capacitor's "safety limit." The 450V rated voltage allows it to easily handle mains voltage fluctuations, preventing circuit failures due to voltage breakdown, even during peak power consumption or unstable power grids.

Self-Healing Performance (SH - Self-Healing): SH stands for "self-healing" structure. If a local breakdown occurs in the capacitor's internal film, this technology quickly evaporates the metallized layer around the breakdown point, automatically insulating the damaged area and restoring normal operation. This means that even if subjected to instantaneous high voltage, it will not be completely damaged, significantly extending its lifespan.

Safety Protection Design: It integrates an internal pressure explosion-proof device. When the capacitor generates heat or gas due to overload, the explosion-proof valve will sense this and disconnect the connection in time, preventing physical cracking or damage and ensuring the overall safety of the appliance.

High Durability and Low Loss: Using metallized polypropylene film as the dielectric, it has extremely high insulation resistance and extremely low dielectric loss. This ensures that the capacitor itself generates very little heat during long-term power-on, thereby improving the motor's operating efficiency and reducing unnecessary energy loss.

Industry Application Scenarios: This model is commonly used in the starting of air conditioner compressors, the operation of automatic washing machine motors, and dryers. It can effectively withstand the impact current caused by frequent starts and stops, and is a key component in ensuring smooth starting and quiet operation of the motor.
