Film capacitors, also called plastic film capacitors, are types of capacitors that contain a thin plastic film as the dielectric most commonly called Mylar. 473PSB252K2H film capacitors are polarized, meaning they can only be installed in a circuit in a manner that ensures that the voltage across the device is always positive on one electrode and negative on the other.

The 473PSB252K2H combines low cost with high quality. It features low ESR, high capacitance and has low ESL and contributes effectively to the reduction of noise. It provides a viable solution in circuit design and has wide applications, making it a popular choice for applications which require high efficiency and reliability.

473PSB252K2H offers excellent characteristics for increasing the stability and reliability of the circuit design, and is particularly well-suited for high voltage and high frequency applications due to its high operating temperature. It is especially useful in application fields such as mobile phones, satellite receivers, ADSL modules and laptop computers.

The working principle of the 473PSB252K2H is based on the fundamentals of capacitance. Two electrodes are place either side of a dielectric, which is generally a paper, polymer or ceramic material. When the voltage across the electrodes is increased, electrons are moved from the negative electrode to the positive one. As the charges accumulate on the electrode plates, a capacitance is formed, and the capacitor stores the energy.

The 473PSB252K2H uses Mylar film as its dielectric. It provides stiffer layers that offer higher voltage insulation compared to paper capacitors, meaning that it can operate at higher voltages for less charge. They also have significantly higher leakage current ratings as their layers are airtight and, in most cases, are hermetically sealed. Thanks to the Mylar construction, they can also withstand abusive conditions far better than paper capacitors.

In conclusion, the 473PSB252K2H film capacitors are an ideal choice for applications that require increased stability, long term reliability and high efficiency in an affordable package. Their features, such as low ESR, low ESL, great flexibility and excellent capacitance, make them suitable for high voltage and high frequency applications, such as those found in mobile phones, satellite receivers, ADSL modules and laptop computers.
