    What is the function of the piezoelectric ceramic crystal of drive circuit inductor

    The function of the piezoelectric ceramic layer inductor is mainly to transmit DC and block AC. It mainly plays the role of filtering, oscillation, delay and notch in the circuit. Inductive coils block AC current. The size of the blocking effect is called inductive reactance x1, and the unit is ohms

    Low thermal conductivity and high mechanical strength of piezoelectric ceramics

    Piezoelectric ceramics are mainly used to guide special piezoceramics with low thermal coefficient and poor heat transfer. The thermal insulation piezo ceramics mainly use zirconia and alumina ceramic materials. The zirconia materials have low thermal conductivity and are used as thermal insulation

    Principle of piezoelectric effect and its application of piezo ceramics

    When some dielectrics are deformed by an external force in a certain direction, polarization occurs inside them, and positive and negative opposite charges appear on the two opposite surfaces thereof. When the external force is removed, it will return to the uncharged state. This phenomenon is calle
