For films that should be used as a dielectric in a capacitor, the dielectric constant should be high so that the capacitor dimensions can be minimized. The dielectric constant is affected by temperature and current frequency. View chapter Chapter Mobile Phases and Their Properties Essentials in ...
Vibration-level characteristics of lead-zirconate-titanate ceramics were studied using the constant current driving method. It was found that resonant freq... S Takahashi,S Hirose - 《Japanese Journal of Applied Physics》 被引量: 89发表: 1992年 Bulk Photovoltaic Effect in Reduced/Oxidized Lead Lant...
Flexible copper clad laminates are used in flex and rigid-flex circuits because of their mechanical properties.The FCCL circuit application is in low transmission frequency,high-frequency dielectric properties such as dielectric constant(Dk) and dielectric loss tangent(Df) which are paid less attention...
is very fast and can follow high-frequency fields, while ionic polarization, which involves the displacement of the positive and negative ions in the lattice, is slower and can only follow low-frequency fields. The result is that the dielectric constant decreases with increasing frequency, which ...
Some commonly used as a power amplifier, a dielectric constant of 2.55 (e.g. Arlon Diclad527, AD255, etc.) or a dielectric constant of 3.5 (such as AD350,25N/FR). There is also a 4.5 dielectric constant (such as AD450), mainly from the FR-4 design for high frequency applications...
摘要: In the design of high-frequency (or fast-impulse) capacitors required to hold off high voltages, one can use high-dielectric-constant materials (e.g., certain ceramics). This paper considers some of the high-frequency problems of such capacitors and techniques to mitigate them....
The frequency dispersion of the dielectric constant of yttrium (Y)-doped (Ba,Sr)TiO3 thin films (Y-BST) in the high-frequency domain (10 kHz–67 GHz) was investigated. In order to remove the substantial parasitic capacitances, inductances, and resistances from the measured impedance data, ...
The frequency of the applied voltage also affects the dielectric constant. As the frequency increases, the dielectric constant becomes non-linear and its value decreases more rapidly as the frequency increases. At high frequencies, electric power loss increases. This is one reason why materials with...
