Film Capacitors

Film capacitors, also known as plastic dielectric capacitors, are a combination of electro-mechanical components consisting of two conducting surfaces (plates) separated by a thin plastic film and wound to form electrical capacitors. Film capacitors are often used in analog circuits and for signal filtering purposes due to their very low ESR (equivalent series resistance), high ripple current ratings, and long service life.

BFC238362243 is a film capacitor specifically designed to provide high-frequency noise suppression for electronic instruments. It is composed of two conductive aluminum-zinc alloy electrodes or plates and a polytetrafluoroethylene (PTFE) dielectric film. The electrodes are wound into a capacitor with two layers of solid aluminum foil for maximum electrical stability.

The wide operating temperature range, good self-healing property, and low dielectric loss of BFC238362243 make it ideal for use in applications such as frequency converters, ballasts, and drives where high-frequency interference needs to be suppressed. It is also used in medical equipment and lighting systems, telecommunications, computer networks, radar and navigation equipment, and automotive electronics for effective signal interference suppression.

Working Principle

The working principle of BFC238362243 is based on the principal of capacitance. When a voltage is applied across the two conductor plates of the capacitor, it then acts as an electric field, changing the electrical properties of the PTFE dielectric film in between. This provides a capacitance value of 39.5nF (nanofarads) at 25C. The dielectric properties of the PTFE resin allow for a high frequency of 1MHz, and the high dielectric strength of 700V DC allows it to withstand high voltage operations.

The PTFE material ensures that there is no significant deterioration of capacitance or dissipation factor over time, making BFC238362243 an ideal selection for long-term use under sustained voltages. In addition, the high level of flexibility and dielectric strength makes BFC238362243 suitable for use in places where space is limited. Its strong resistance to temperature shifts, higher voltages and humidity make it an excellent choice for industrial and commercial applications.

BFC238362243 is UL certified, RoHS compliant and offers an operating temperature range of -55°C to +105°C. It is also a cost-effective product and can be easily installed with its low profile and lightweight design.

In short, BFC238362243 is a high performance film capacitor that provides effective signal interference suppression, a wide operating temperature range, good self-healing properties, and a high dielectric strength. It is a reliable solution for use in high-frequency applications and industries where switching frequencies need to be suppressed.
