Film capacitors, also called Polyphenylene Sulphide Film Capacitors (PPS), have a variety of applications and are gaining widespread popularity, especially in consumer electronics. These capacitors are used in areas such as defense, aerospace, automotive, consumer electronics, medical electronics and industrial control applications. The MKT1817282254G is an ideal choice for these applications due to its reliable performance and excellent features.

The MKT1817282254G is a surface-mounted film capacitor that features a reverse-polarity construction. The reverse-polarity construction prevents shorting and reduces the amount of electrical noise that can build up on the capacitor over time. This design also allows the MKT1817282254G to dissipate heat more quickly and efficiently, ensuring it has a higher operating temperature range than most film capacitors.

The MKT1817282254G also features high reliability and excellent vibration and shock resistance capabilities. The capacitor is designed with an industry-standard EIA 535-BAAC lead-free technology which ensures its compatibility with different types of boards and components. Additionally, the capacitor is also compliant with RoHS and REACH regulations.

The MKT1817282254G film capacitor also features a wide voltage range of up to 4500 VDC and is rated for a capacitance of 1817 pF and a maximum dissipation factor of 0.25. This ensures that the capacitor works efficiently and accurately across a wide range of applications and temperatures. The capacitor also features a wide frequency range of up to 30 kHz which allows it to work at high frequencies, ensuring that it performs reliably in high-frequency applications.

The working principle of the MKT1817282254G film capacitor is based on the electrostatic principle. The capacitor is composed of two parallel plates of thin film that are insulated by an insulating film mil. When a voltage is applied to the capacitor\'s plates, the charge is trapped between the two plates and creates an electric field. This electric field causes the current to flow through the two plates and capacitance is generated. The capacitance generated by the capacitor is proportional to the area of the two plates and the distance between them. The MKT1817282254G is designed to provide high precision and stability, and is capable of handling high frequencies and voltages.
