Thin Film Capacitors

Thin film capacitors are constructed from a thin layer of superior dielectric material deposited on a substrate, usually through in-vacuum deposition. Conventional capacitors are typically made from a wound silver foil or a paper dielectric with metalized ends. Thin film capacitors offer a much more reliable capacitance and therefore more consistent performance, whether the applied voltage is AC or DC. By being constructed from a thin material, thinner total profiles can be achieved, meaning that thin film capacitors are often used to save space in circuit designs.

The 0402ZJ7R5BBWTR chip capacitor is a common and popular example of a thin film capacitor. This device is constructed from a tried and tested dielectric material, providing higher capacitance in a much thinner package than traditional capacitors. The 0402 chip comes with a surge voltage rating of 8volts, enabling the device to handle higher voltage transients with ease. The device is available in many variants and can be used with either AC or DC voltages.

The working principle of a thin film capacitor is based on the simple capacitance result due to metal-dielectric interface. Since dielectric is made of a very thin material, it provides higher capacitance. The level of capacitance is dependent on the permittivity of the dielectric and the distance between the metal plates. The metal plates act as the two electrodes, with the dielectric in between them. The AC or DC voltage is applied to the electrodes and creates an electric field, storing electrical charge and creating capacitance. As the voltage is increased, thedistance between the electrodes increases, thus reducing the capacitance.

The 0402ZJ7R5BBWTR thin film capacitor\'s applications span across a wide range of industries. Consumer appliances, medical electronics and automotive electronics; each require compact and reliable capacitance solutions. Military and aerospace electronics must often be able to withstand extreme environmental conditions and as a result thin film capacitors are often the capacitors of choice in these stages. Thin film capacitors are also extensively used in RF applications for their high reliability and stability, excellent temperature performance and high frequency characteristics.

The 0402ZJ7R5BBWTR thin film capacitor is a reliable and cost-effective capacitor choice for a wide range of applications and industries. With excellent performance levels, this device offers high capacitance, low losses and high surge voltage ratings, enabling the designer to achieve a high level of performance with total confidence.
