Thin Film Capacitors

Thin film capacitors are electrical components that are made by depositing thin films of conductive and insulating materials onto a substrate. They serve as a variety of functions, such as providing capacitance, filtering, suppression, and decoupling. These components are commonly used in high-frequency and high-temperature applications due to their ability to offer low leakage, high insulation resistance, and high frequency stability.

08051K2R2BBTTR Application Field and Working Principle

The 08051K2R2BBTTR is a surface mount, thin film capacitor ideally suited for a wide range of applications. The product offers operating temperature range of -55°C to +125°C with a maximum voltage rating of 250 VDC. It is commonly used for power supply filtering, snubber or energy storage in general electronics.

The 08051K2R2BBTTR thin film capacitor is a two-terminal device with two ceramic dielectric layers. The first ceramic dielectric layer is a thick ceramic dielectric. The second layer is a thin film dielectric which is between 100nm to 400nm in thickness. This thin film dielectric layer is deposited onto the substrate, while the upper and lower electrodes are screen printed onto the thin film surface. The two electrodes are separated by the dielectric layer and can be viewed as two parallel plates facing each other and separated by an insulating dielectric material. Due to the small size of this thin film capacitor, it can offer very low ESR and impedance, therefore, making it ideal for high-frequency and high-temperature applications.

This type of capacitor has excellent non-linearity and frequency response characteristics which make it highly suitable for applications such as snubber design, power supply filtering, and smoothing applications. The 08051K2R2BBTTR features low ESR, high thermal stability, and high power rating, making them suitable for high-power applications. They offer high insulation resistance and excellent dielectric properties, making them suitable for DC- choke applications. This type of capacitor is also used for energy storage and EMI/RFI filtering applications.

In short, 08051K2R2BBTTR thin film capacitors are designed with two ceramic dielectric layers, which provide them with excellent performance in high frequency and high temperature applications. With a wide operating temperature range, and high insulation resistance, these capacitors are suitable for a variety of applications such as power supply filtering, snubber, power storage, EMI/RFI filtering, and DC-choke. All these features make this thin film capacitor suitable for use in high-power applications, such as military and aerospace systems, computer systems, and instrumentation and telecommunication systems.
