Film capacitors are electrical components that store energy in an electrostatic field. They are one of the most versatile and widely used types of capacitors due to their high capacitance and wide operating range. The OTBH504KNPIR is a metallized polypropylene film capacitor that is specifically designed for AC filtering and DC blocking applications. It is lightweight, reliable and offers superior electrical properties.

A Overview of Film Capacitors

Film capacitors or plastic film capacitors are electrical components that use thin plastic film as the dielectric medium. The film is either wrapped around a metal core or wound into sheets. The metal layer acts as the electrode or plate and the electrical current is stored in the form of electric flux between the metal plates and the dielectric medium. The capacitance of a film capacitor depends on various factors such as the film material, thickness, size and amount of metal used. Film capacitors are reliable, compact and have excellent frequency and temperature characteristics. They are used in a wide variety of applications including motors, generators, transformers, amplifiers, radio frequency systems and medical imaging equipment.

OTBH504KNPIR Application Field and Working Principle

The OTBH504KNPIR is a small, metallized polypropylene film capacitor that is specifically designed for AC filtering and DC blocking applications. It offers superior performance with regards to frequency and temperature characteristics compared to other types of capacitors. It is suitable for line-to-line AC filtering applications where low ESR and high noise suppression are required. It has a tolerance of +/- 10%, a capacitance range of 1-500 Micron F and a DC working voltage of 250VAC.

The OTBH504KNPIR uses a thin plastic film, such as polypropylene, as the dielectric medium. The metal layer acts as the plate or electrode and the electrical current is stored in the form of electric flux between the metal plates and the dielectric medium. The thickness of the dielectric medium and the amount of metal used determines the capacitance of the film capacitor. In AC filtering applications, the OTBH504KNPIR helps suppress high-frequency ripple currents and transients on the AC line. In DC blocking applications, it helps block voltage from passing through the capacitor and protects sensitive equipment from damage.

Advantages of the OTBH504KNPIR

The OTBH504KNPIR offers a range of advantages for electrical engineers and designers in both AC filtering and DC blocking applications. These include:

• It is lightweight and has small dimensions, making it suitable for space-constrained PCB designs.
• It has excellent ESR and frequency characteristics across the entire operating temperature range.
• It has a long service life due to its high voltage and temperature endurance capability.
• It is resistant to moisture and shock, making it suitable for use in harsh environmental conditions.
• It is UL 94V-2 rated, which means it meets the standards for use in electrical and electronic equipment.

Conclusion

The OTBH504KNPIR is a small, reliable metallized polypropylene film capacitor that is specifically designed for AC filtering and DC blocking applications. Thanks to its superior electrical characteristics, small size and long service life, it is one of the most popular film capacitors on the market today. If you are looking for a compact, reliable film capacitor for your project, the OTBH504KNPIR is an excellent choice.
