Film capacitors are electrical components that share characteristics with traditional ceramic and electrolytic capacitors, but are made from film dielectrics. Capacitors made from film dielectrics are capable of handling higher currents than ceramic capacitors and also provide greater stability against temperature, humidity and frequency variation than electrolytic capacitors. The B32560J8472K289 is a film capacitor designed for applications in power electronics, measuring instrumentation and telecommunications circuits.

Applications

The B32560J8472K289 is a polypropylene film capacitor specifically designed for use in power electronic, measuring instrumentation and telecommunication circuits. It is well suited for applications where a high-temperature stability and a large capacitance are required. It is also used for coupling, decoupling, oscillation, and filter circuits. Its relatively high capacitance and small profile makes it suitable for applications such as AC motor drives, automotive onboard electronics, AV equipment, photovoltaic inverters, uninterruptible power supplies, industrial power converters, lighting and solar energy systems.

Working Principle

The B32560J8472K289 is a polypropylene-film capacitor with a radial lead-out design. It is a non-polar capacitor with a dielectric of polypropylene film and a metallized surface. The metallized surface forms an electrode on both sides of the polypropylene film. With a dielectric of polypropylene film it has high breakdown voltage, high temperature stability, and a large capacitance. When a voltage is applied across the capacitor, the electric field forms near the deposited metal and a capacitance is formed. The capacitance is a measure of the amount of charge stored on the capacitor plates and changes in the dielectric material affect the capacitance. As AC signals pass through the capacitor, the voltage is applied, and the capacitor stores the excess electric charge.

In addition to providing a large capacitance, the B32560J8472K289 also has a self-healing property which means that it can withstand high surge and over-voltage conditions. This self-healing capability is due to the heating of the dielectric material at the point of short circuit and then the dissolution of the point of short-circuit. This allows the capacitor to remain safe and intact, even after a large surge or over-voltage.

Conclusion

The B32560J8472K289 is a polypropylene film capacitor designed for applications in power electronics, measuring instrumentation, and telecommunications circuits. Its relatively high capacitance and small profile make it suitable for applications such as AC motor drives, automotive onboard electronics, AV equipment, photovoltaic inverters, uninterruptible power supplies, industrial power converters, lighting and solar energy systems. It has a self-healing property which means that it can withstand high surge and over-voltage conditions.
