Several key parameters to consider when purchasing CBB film capacitors

There are a great many types of film capacitors. Taking metallized polypropylene film capacitors as an example, there are mainstream models and customized models, and even thousands of types. This makes it quite a headache to select CBB capacitors.

In fact, the design of CBB film capacitors is not complicated; we only need to focus on a few key parameters.

Actually, finding the correct film capacitor model is quite simple; you only need to know these parameters when inquiring.

1. Capacitance. Taking CBB22 capacitors as an example, their capacitance range is 0.0047-3.3Uf.

2. Tolerance. Common tolerance ranges are: ±5% (J), ±10% (K), ±20% (M).

3. Size. This is the most common size, and custom production is also possible.

4. Voltage. Mainstream voltages are 250V, 400V, and 630V.

5. Material.

6. Lead spacing and lead length.

If you really don't know how to choose a model, the simplest way is to let the manufacturer help you. Manufacturers usually have a large customer base and can quickly and successfully design a model based on their experience and your requirements.
