Research on SMD Capacitor for RF Protection of SCB Initiators

Abstract:

According to the radio frequency effect mechanism, the performances of SMD capacitor used for RF protection of SCB initiators were studied theoretically and experimentally. The 99.9% firing RF power of SCB initiators without any protection is 14.15W, but none of SCB initiators in parallel with SMD capacitor fired at 20W. The results of capacitor discharge experiment indicate that SMD capacitor has no influences on electrical explosive performances of SCB initiators. Its RF protection capability for SCB initiators of SMD capacitor was tested by RF sensitivity experiment, and the results show that it could significantly reduce the RF sensitivity of SCB initiators when in parallel with appropriate SMD capacitor.
