Working Principle

The 04021J1R8PBSTR thin film capacitor works on the principle of piezoelectricity, in which two plates separated by a non-conducting dielectric layer act asa capacitor. When a voltage is applied to the capacitor, the two plates in the dielectric layer will expand and contract as the electric field interactswith the plates. The expansion and contraction cause the capacitance of the capacitor to change and this is known as the piezoelectric effect.Moreover, this capacitor also features a self-resetting construction and a self-limiting current capability which makes it ideal for applications that require high temperature or high energy operation.
