The article expounds the pyroelectric effect of the ceramic filter when the temperature changes rapidly, and observes the pyroelectric voltage generated when a ceramic filter rapidly changes in temperature by experiments. The combination of theory and experiment is used to study the effect of heat The effect of power release on the subsequent circuit components and provides a method of preventing the latter circuit components from being compromised.
