Film capacitors, with their small size, both high temperature and high frequency operating capability, typically help to reduce the components’ weight and mounted area in electronic systems. These capacitors have a wide application field, as they are used frequently as an alternative to electrolyte, ceramic, and mica capacitors, in order to save board space while achieving higher efficiency. The latest innovation of film capacitors is the ECQ-B1152JF, which represents one of the modern standards in the industry.

The ECQ-B1152JF capacitor is characterized by low ESR and ESL values, which ensure high-quality performance, while also being low on electromagnetic interference. This type of capacitor is relatively small in size, with a maximum dimension of 11.30×5.20 mm, and is usually available in an aluminium casing that can withstand temperatures up to 160 °C. It also offers excellent quite performance, allowing it to be used in areas of high noise levels.

The capacitance of the ECQ-B1152JF capacitor ranges from 10 pF to 2,500 pF, with maximum operational voltage of 200 VDC. The ECQ-B1152JF application field includes mostly power applications, where high volume capacitors are needed to increase reliability, along with applications in aerospace, automotive, industrial, and military. As a result, these film capacitors are used in various power circuits, such as converter, inverter, motor drive, or resonant circuits.

The ECQ-B1152JF capacitor model works on the basis of a polyethylene naphthalate (PEN) film dielectric that offers high insulation and low dissipation factors. The dielectric also has a temperature rise of 10K when it is subjected to continuous operation at a frequency of 100KHZ and an applied voltage of 50 Vrms. The length of film is 9.5 cm and it makes use of tight windings on an aluminum core for higher initial capacitance values.

The ECQ-B1152JF capacitor operates on the basis of the parallel plate capacitor design, where two identical metal plates separated by an insulating material create a structure that stores electrical charge on its surfaces. These plates act as electrodes and the insulating material is the dielectric. The voltage applied to the electrodes will then create an electric field between the electrodes, resulting in a capacitance that is determined by the dielectric material and surface area of the electrodes.

In addition, the shape of the aluminum core of the ECQ-B1152JF capacitor affects both the capacitance and the dimension of the capacitor. The aluminum core allows the whole structure to be small and light, while helping to reduce the number of lead wires that need to be connected to it. Furthermore, the capacitor’s casing prevents damage from environmental elements, such as dust or humidity.

The ECQ-B1152JF is the ideal choice for most applications that require a reliable and high performing film capacitor. Its small size and its low ESR and ESL values make it suitable for a variety of electronic applications, such as power circuits, aerospace, automotive, industrial, and military products. The PEN film dielectric of the ECQ-B1152JF provides a robust and reliable covering that ensures long-term durability and high-quality performance in any application.
