Cbb65 14.5+4.5uf 500v S3 C Lead

This CBB65 14.5+4.5μF 500V S3 C Lead capacitor is a dual-run start capacitor specifically designed for large household appliances. It not only determines whether the motor can start smoothly but also directly affects the efficiency and current stability of the equipment during operation.

Key Features:
Dual Electrolytic Specifications and Integrated Design:  It utilizes a composite capacitance structure of 14.5+4.5μF. This "two-in-one" design is primarily for systems with compressors and fan motors (such as air conditioners). The larger capacitance drives the compressor, while the smaller capacitance precisely matches the fan, significantly saving installation space and simplifying internal wiring.

Self-Healing Metallized Film Technology: The core dielectric material possesses strong self-healing capabilities. When a small voltage breakdown occurs internally, the metallized coating at the damaged area quickly evaporates, automatically insulating the fault point and preventing short-circuit failure. This feature ensures that the capacitor maintains a stable capacitance even in environments with frequent power grid fluctuations.

S3 Level Physical Explosion-Proof Safety Architecture:  It features a built-in mechanical pressure disconnect device. In the event of extreme overload or the generation of a large amount of gas at the end of its lifespan, the capacitor casing will slightly expand, physically disconnecting the internal connecting wires. This non-electronic hardware protection mechanism ensures that no fire or explosion occurs under abnormal conditions, meeting the S3 safety standard.

Low Loss and Temperature Rise Control: The product has an extremely low dielectric loss angle (Tan δ). This means that very little heat is generated when current passes through the capacitor, which not only improves energy conversion efficiency but also effectively prevents performance degradation caused by overheating, ensuring the motor's long-term continuous operation.

Impact Current Resistance:  Designed for the frequent start-stop characteristics of compressors, this model strengthens its ability to withstand instantaneous impact currents. High insulation resistance combined with an optimized lead structure ensures that the electrode edges will not be burned out under the high-voltage, high-current impact during motor startup.

Industrial-Grade Voltage Redundancy: The rated voltage is 500V. Compared to the commonly available 450V specifications, it offers a higher voltage tolerance margin, allowing it to more easily handle power grid harmonic interference and instantaneous inductive overvoltage.
