Working Principle

The BFC241949102 series of capacitors employ a polyester film as the dielectric material and a copper-clad strip as the electrode. The dielectric material has excellent tracking resistance, selectivity, and high dielectric strength, and is wrapped into a cylindrical shape. The capacitance of the capacitor is determined by the ratio of the area of the electrodes to the thickness of the dielectric material. The capacitance decreases as the thickness of the dielectric material decreases.

The electrodes are made from copper-clad strips which are then plated with an insulating material. The insulation material helps protect against shorting due to the presence of moisture or other contaminants. The circuit connection terminals are made from brass and are gold plated for corrosion protection. For signal and timing applications, the capacitors employ a special metalization process, which uses low contact resistance materials.

The BFC241949102 capacitors feature a large solid capacitor structure. This structure helps to ensure excellent protection against moisture, dust, and environmental pollutants, making it suitable for use in harsh operating conditions. The capacitor also features low inductance properties, making it ideal for high speed applications.

The BFC241949102 capacitors can be used as a single capacitor or in parallel to increase capacitance. When used in parallel, the combined capacitance is equal to the sum of the individual capacitances. In this configuration, the BFC241949102 capacitor can store up to 100 µF, a value that is sufficient for many low and medium frequency applications.

The BFC241949102 is a reliable and high performing film capacitor series that offers excellent performance in high-frequency signal and timing applications. By combining superior insulation resistance, high frequency stability, low ESR, and low dissipation factor, the BFC241949102 is an ideal choice for a wide range of applications.
