Film capacitors, also known as plastic film capacitors or polymer film capacitors, are components that are similar to standard electrolytic capacitors in design. However, they differ from the latter in two distinct ways: they are much thinner and use a film-based dielectric. Moreover, they are also polarised, meaning they utilise two conductors, with one of them being the dielectric itself. This article will delve into the application field and working principle of the 475MHBS35K2H Film Capacitor.

Applications of 475MHBS35K2H Film Capacitor

The 475MHBS35K2H Film Capacitor is used mainly as a filtering component, absorbing power line frequency spikes and high-level noises. It can also be used in HF bypass applications and power line conditioning. Its wide capacitance range of 0.22 µF to 68 µF makes it great for the aforementioned uses.

The device can come in DMSPOLAR 235 or X2 Var-cap versions – the former is suitable for power line for class x2 and the latter is mainly used for power line applications for class y2.

The clamping voltage of the 475MHBS35K2H Film Capacitor is rated at 5.5 V, with a DC voltage of 10V.

The temperature coefficient of its capacitance also remains stable over a large temperature range, meaning that it can withstand harsh conditions without any performance penalties.

On top of these applications, the 475MHBS35K2H Film Capacitor is often used as a signal conditioning component due to its ability to filter out DC and low frequency noise. Additionally, these components are widely used as snubber circuits (in high wattage configurations) and common mode noise suppression.

Working Principle of 475MHBS35K2H Film Capacitor

The working principle of a film capacitor is simple. It consists of two conductive plates, separated by a dielectric film. When a potential difference is applied to the two plates, the dielectric film is “charged up”. This charge then induces an electrostatic field that opposes the potential difference, keeping the plates from touching each other and denying the flow of current.

Unlike other components, a film capacitor has no limit on the amount of charge it can store, meaning that the electrostatic field can get much stronger as more charge accumulates over time.

The core advantage of film capacitors is that they possess an extremely low dielectric loss. This can be attributed to the chemical stability of their construction materials, which only slightly degrades over time. This means that the dielectric loss of the capacitor will remain extremely low even after years of use.

In terms of physical properties, film capacitors can be very thin and lightweight when compared to other types of capacitors, making them ideal for use in low-profile applications. Furthermore, the wide temperature range of film capacitors means that they can be used in high-temperature environments without any performance issues.

Lastly, film capacitors have a high self-healing capacity, meaning any short circuits that may occur due to age-related wear and tear can be easily corrected by the internal mechanisms of the capacitor itself.

Conclusion

In conclusion, the 475MHBS35K2H Film Capacitor is an extremely versatile component. Its wide temperature range, low dielectric loss, and self-healing capability make it perfect for a variety of uses, from signal conditioning to power line filtering and HF bypass applications. Its wide capacitance range of 0.22 µF to 68 µF also helps ensure that it can accommodate virtually any need.
