Working principle of B32529D3224K189 film capacitor

The basic principle of the B32529D3224K189 film capacitor is the same as other capacitors: When the voltage on the film capacitor is changed, the electric field in the film capacitor changes accordingly. This pressure change in the capacitor causes charge flow from one capacitor plate to the other. The synchronous current, which is called displacement current, will be produced simultaneously and flows in a closed loop between the capacitor plates.

When the voltage on the capacitor is changed, the resulting electric field produces a displacement charge, which flows between the two capacitor plates. The magnitude of the displacement current is proportional to the rate of change of voltage on the capacitor and is independent of the capacitance. Thus, the AC current, or displacement current, flows in the capacitor even if the AC voltage is applied.

The capacitance of the film capacitor is determined by the size and dielectric material of the film capacitor. The dielectric material mainly determines the breakdown voltage, insulation resistance, and dielectric loss of the film capacitor. The higher the insulation resistance and dielectric constant, the larger the capacitance. With the improvement of material manufacturing technology, the product quality of film capacitors has been greatly improved and its application field has been continuously expanded.

In general, B32529D3224K189 film capacitors have excellent features such as high stability and reliability, and are widely used in various circuit systems. Due to its good performance, B32529D3224K189 is an ideal choice for many applications and suitable for most operating conditions.
