Film capacitors

Film capacitors, also known as plastic film capacitors, are capacitors that are made of thin dielectric films. These capacitors are widely used in DC power supplies, audio circuitry, instrumentation, medical electronics, and precision high-voltage power electronics. The types of film capacitors available include polyethylene napthalate (PEN), polyethylene terephthalate (PET), polypropylene (PP), and polystyrene (PS).

BFC237155183 application field and working principle

The BFC237155183 is a polypropylene (PP) film capacitor that can operate at very high voltages. It is designed for use in medical electronics, as well as for other challenging applications requiring reliable, high voltage operation. 。It has a maximum operating voltage of 1.5kV, which makes it suitable for applications such as motor drives, laser control, and X-ray circuit control.

The BFC237155183 has a capacitance range of 0.2 to 33 uF, and is available in a wide variety of case sizes. It is rated for temperature range of -55 to +125°C, and offers excellent reliability and low leakage current. The film capacitor also provides protection against electromagnetic interference (EMI) and is RoHS compliant.

The working principle of the BFC237155183 is based on the electrostatic phenomena between two electrically conducting surfaces called electrodes, separated by a dielectric (insulating material). When these two electrodes are connected to a DC power supply, electrons are attracted to the negative electrode, resulting in an electric field that induces a charge on the dielectric. This stored electrical energy is known as capacitance.

The BFC237155183 capacitor utilizes a polypropylene film as the dielectric to allow for consistent charge storage and efficient energy transfer between the conductors. The terminal covers are also designed with a combination of PVC and ABS to shield against mechanical, chemical, and electrical stresses.

In conclusion, the BFC237155183 is a polypropylene film capacitor that is designed to operate reliably at very high voltages. It has a wide capacitance range of 0.2 to 33 uF, and can operate in temperatures ranging from -55 to +125°C. Its robust construction provides excellent protection against electrical and electromagnetic interferences, making it an ideal choice for medical electronics and other challenging applications.
