Electronic components and circuits that produce electromagnetic interference when they are powered by sources

Feature of Cbb20 metalized polypropylene crossover capacitors:

1.Non-inductive construction and self-healing
2.Low DF and high IR
3.High capacitance value available and compact size

CBB23 capacitors are mainly used in RC step-down circuits as RC step-down capacitors.

CBB23 is a non-certified boxed capacitor. It uses polypropylene film medium, flame-retardant plastic case, epoxy resin seal, and CP wire leads out. High cost performance, low capacitive drop, good appearance consistency, replaceable encapsulated capacitors, suitable for 110~240VAC RC step-down circuits. Compared with epoxy resin-encapsulated capacitors, it has better high temperature resistance and high humidity performance, longer product life, and less capacity fading.

Here are some key features and characteristics of CBB20 Metallized Polypropylene Film Capacitors:

1. Capacitance: CBB20capacitors have a specific capacitance value measured in farads (F) or microfarads (µF). The capacitance value determines the amount of electrical charge the capacitor can store.

2. Metallized Polypropylene Film: The dielectric material used in CBB20 capacitors is metallized polypropylene film. This film is highly stable, has low losses, and offers good insulation properties.

3. Metallized Construction: CBB20 capacitors have a metallized construction, where a thin layer of metal is applied to both sides of the polypropylene film. This metallization allows for self-healing properties, reducing the risk of capacitor failure in case of minor electrical breakdowns.

4. Voltage Rating: CBB20 capacitors have a specified voltage rating, which indicates the maximum voltage that the capacitor can withstand without breaking down. It is crucial to select a capacitor with an appropriate voltage rating for the specific application to ensure reliable operation.

5. Application Range: CBB20 capacitors are commonly used in applications such as power supplies, lighting circuits, motor controls, audio equipment, and various electronic devices. They are suitable for filtering, decoupling, coupling, and timing applications.

When selecting a CBB20 capacitor for a particular application, it is essential to consider the desired capacitance, voltage rating, and any other specific requirements of the circuit or system. Always refer to the manufacturer’s datasheet or specifications for detailed information on the specific CBB20 capacitor you are using.
