Film capacitors, also known as plastic film capacitors, are devices that store electrical energy and are composed of thin dielectric insulator material such as polyester, polypropylene, paper or Teflon. Film capacitors come in a wide variety of packages and sizes and can be used in numerous applications. The present article is focused on the R76UI1470SE40J model and its application field and working principles.

The R76UI1470SE40J film capacitor is a radial-leaded device with a 20mm lead spacing and a 7mm diameter. It is rated for 7μF and the rated voltage is 250VAC (50Hz). It is made of non-inductive and self-healing polypropylene material with a dielectric status of 85%. This model is suitable for a broad range of applications such as line-filter capacitors, start and run capacitors, pulse-discharge capacitors, signal-lines and supply-lines filtering.

Capacitance is one of the main characteristic of a capacitor and this coil has the essential feature of providing 7 μF of capacitance. Its value specifies the amount of electric charge stored by a capacitor in response to a potential difference. It is measured in Farads [F]. Higher capacitance allows for higher power-supply peak currents and longer sustained cycles of operation. Film capacitors of this model also provide excellent temperature stability as well as low temperature-coefficient. This makes it suitable in numerous temperature-sensitive applications.

The R76UI1470SE40J film capacitor also exhibits very low impedance, an important factor for the capacitor\'s energy storage capacity. This allows it to store higher energy levels in its capacitance and the energy is released quickly. This makes it advantageous when responding to short duration discharges and while handling high RF noise. The fact that it is made of dielectric insulation material also makes it ideal for operating in high-temperature and humid environments. Furthermore, this material provides also improved noise cancellation which is quite desirable for particular applications.

The working principles of the R76UI1470SE40J film capacitor involves the capacitance of two conducting surfaces when close together. This is accomplished by having two metal plates separated by an insulating dielectric material. When an AC voltage is applied to the coil, the inner conductor stores electric charge due to the capacitance and then this charge is released back to the outer plate. This process happens in fast cycles according to the input frequency. As the charge is stored and released, electric-field and dielectric polarisation appears, generating a potential difference between the capacitors terminals.

To conclude, the R76UI1470SE40J capacitor is a device with a wide range of applications involving line-filters, start and run capacitors and noise cancellation. Its robust construction and high dielectric qualities make it a suitable choice for high-temperature and humid environments. Its working principles involve the storage and release of electric charge due to the capacitance of two metal plates separated by an insulating dielectric material.
