Abstract

Un circuito resonante para usarse con un sistema de detección de ondas de radio para la prevención de robos en tiendas o similares, el cual tiene un circuito de bobina y capacitor, para lo cual el circuito se destruye permanentemente cuando la etiqueta se expone a una señal de radio que produzca un voltaje a través del capacitor que exceda el voltaje de ruptura del capacitor. El capacitor consiste de un dieléctrico que no presente autoregeneración. Tales dieléctricos incluyen cerámica, óxidos metálicos y minerales.
