jb Temperature Humidity Bias (THB) Series - JFWT

jb Capacitors Company can offer the regular X2 capacitors, called JFW - X2 Metallized Polypropylene Film Capacitor (310VAC), but we also have the series that has high stability of capacitance under severe ambient condition (high temperature and high humidity). The series is JFWT. And, it can be used in across-the-line, interference suppression circuit.

And, for this kind of capacitors, it has safety approval of VDE, ENEC and UL approvals. So that you have certain quality assurance. Also, we have short delivery because sometimes we will have hot sell capacitance items that have stock available. Finally, jb can offer good prices for this series. It is one of jb’s strong series.

Application: Power meter, LED driver, Sever ambient condition applications.

jb Flatband Energy Diagram Of A Metal-Oxide-Semiconductor (MOS)

The flatband diagram is by far the easiest energy band diagram. The term flatband refers to fact that the energy band diagram of the semiconductor is flat, which implies that no charge exists in the semiconductor. The flatband diagram of an aluminum-silicon dioxide-silicon MOS structure is shown in Figure 6.2.4. Note that a voltage, VFB, must be applied to obtain this flat band diagram. Indicated on the figure is also the work function of the aluminum gate, FM, the electron affinity of the oxide, coxide, and that of silicon, c, as well as the bandgap energy of silicon, Eg. The bandgap energy of the oxide is quoted in the literature to be between 8 and 9 electron volt. The reader should also realize that the oxide is an amorphous material and the use of semiconductor parameters for such material can justifiably be questioned.

The flatband voltage is obtained when the applied gate voltage equals the workfunction difference between the gate metal and the semiconductor. If there is a fixed charge in the oxide and/or at the oxide-silicon interface, the expression for the flatband voltage must be modified accordingly.
