Capacitors play a vital role in numerous electronic applications, improving performance and efficiency. Housed in a sleek cylindrical aluminum housing, this versatile component can be used in everything from motor operation and HVAC systems to residential and commercial settings. Combining durability with style, capacitors are essential to modern electrical systems.

CBB65 is a metallized polypropylene film capacitor widely used in circuits such as motor starting and running, power supply, lighting, etc. According to the pictures you provided, there are many models of CBB65 capacitors, the main difference is their capacitance (Capacitance) and corresponding dimensions (Dimension-Diameter x Height).

CBB65-2 model features:
Capacitance ranges from 7.5μF to 80μF.
Dimensions vary with increasing capacitance, from 45x55mm to 60x105mm.
Applicable to voltage ranges of 370VAC-400VAC and 440VAC-450VAC.

CBB65-3 model features:
Capacitance ranges from 20μF to 80μF, with tolerance (such as 20+5μF means a nominal value of 20μF, with a tolerance of +5μF).
Dimensions also vary with increasing capacitance, from 50x65mm to 60x120mm.
Also suitable for voltage ranges of 370VAC-400VAC and 440VAC-450VAC.

Common features:
Both types of capacitors have high insulation resistance and low losses.
They both have self-healing properties, which means that when a local breakdown occurs inside the capacitor, the insulation performance can be automatically restored.
The size design of the capacitor takes into account the installation space and heat dissipation requirements.
When selecting a CBB65 capacitor, it is necessary to determine the appropriate model and size based on the actual application voltage range, required capacitance and installation space.
