Film capacitors, sometimes known as plastic film capacitors, have been deemed as a more cost-targeted alternative to the traditional capacitors composed of ceramic, silver mica, paper, oil-filled, and electrolytic components–all of which use a different material to construct the dielectric layer. As such, film capacitors have taken a popular position in the capacitor market through the widespread use of polyester, polycarbonate, polypropylene, polystyrene, polyethylene naphthalate (PEN) and metallized film capacitors. Among other factors, this is due to their low ESR, a wide temperature range, good pulse capability, and the ability to meet the necessary safety requirements and insulation requirements of many applications. B32653A4224K000, a film capacitor produced by EPCOS, is no exception.B32653A4224K000 is a polypropylene film capacitor with radial leaded terminations that offers good performance for filtering, decoupling and snubber applications. It is available with a rated voltage of up to 400VDC, a capacitance range of 2.2nF-100nF and a tolerance of ±10%. In addition, the B32653A4224K000 capacitor is rated for temperatures up to 70°C and has an aluminum-plated tinned copper wire which facilitates a secure connection.In terms of operating principles, the B32653A4224K000, as with all other film capacitors, is composed of a “dielectric” and two metal plates. The dielectric is the “insulating” layer between the two metal plates, which can be constructed of many different types of materials such as Mylar, polypropylene, and polycarbonate. Since this layer acts as an insulator, it prevents current from flowing between the two metal plates and instead allows only energy to be stored and released when the charges on the plates are out of balance.In these capacitors, the stored energy is proportional to the voltage that is applied across the capacitor’s terminals and the dielectric material used. The internal dielectric thickness is also a key factor, as thinner dielectrics lead to a higher voltage and capacitance, but also a lower capacitance tolerance and higher leakage current.Applicationwise, the B32653A4224K000 capacitor is mainly used for filtering, decoupling, and snubber applications. These three application areas, though distinct, are related to one another, and the B32653A4224K000 film capacitor can be used to provide protection for all three. In terms of filtering, the capacitors are often used to reduce the current ripple, noise, and EMI in power supplies, and the B32653A4224K000’s low ESR helps make it an effective filtering device. The high ripple current capability also makes it a great choice for applications that require efficient decoupling, as the capacitor can absorb the sudden voltage transients and therefore prevent any disruptions to the circuit. The B32653A4224K000 is also useful in snubber applications, where the capacitor is connected in parallel to resistive or inductive loads to reduce the effects of high-frequency effects or ringing on the loads.In conclusion, the B32653A4224K000 film capacitor is an ideal choice for many applications, due to its high temperature range, low ESR, and range of capacitance and voltage choices. In addition, the dielectric’s thickness and the aluminum-plated tinned copper wire allow for a secure connection. As such, the B32653A4224K000 offers effective filtering, decoupling, and snubber capabilities, making it a valuable asset for many applications.
