Cbb65 13+5uf 500v C S2, Lead

This CBB65 13+5μF 500V C S2 is a high-performance metallized polypropylene film capacitor specifically designed for the starting and running of high-power motors. It features a dual-capacitance structure (commonly known as a "mother-and-child capacitor"), providing power support for both the compressor and the fan motor simultaneously. It is a key component in the core control circuits of appliances such as air conditioners and clothes dryers.

Technical Features and Application Analysis
Dual-Capacitance Integrated Design (13+5μF): This "two-in-one" specification allows a single capacitor component to handle two different tasks simultaneously. Typically, the larger 13μF capacitance is used to drive the compressor, while the smaller 5μF capacitance controls the operation of the fan motor. This design not only saves installation space within the appliance but also simplifies wiring.

High Voltage Withstand Capability (500V AC): A rated voltage of 500V means it has a higher safety margin in environments with complex voltage fluctuations. Compared to the common 450V specification, it can more easily handle instantaneous surge currents, extending the service life of the motor under harsh operating conditions.

Self-Healing and Loss Control: The internal metallized film dielectric has excellent "self-healing" capabilities – even if a local breakdown occurs internally, the capacitor can quickly restore its insulation performance through electro-physical reactions. At the same time, its low-loss characteristics ensure very low heat generation during long-term operation, maintaining the stability of the system's power factor.

S2 Class Explosion-Proof Safety Standard: The product incorporates a pressure-sensitive circuit breaker (i.e., S2 class safety explosion-proof design). When the capacitor generates internal pressure due to overload or end of life, the explosion-proof valve will actively disconnect the circuit, effectively preventing casing rupture or more serious safety accidents, ensuring the overall safety of the main equipment.

Industrial-Grade Lead Type Interface: The lead-type output enhances installation flexibility. Whether for repair and replacement of older models or internal wiring of compact equipment, the lead connection provides more stable electrical contact, strong vibration resistance, and is less prone to loosening.
