The increased packing density of components on the printed circuit boards leads to increasingly smaller conductor track spacings. Therefore, the CTI value in the base material data sheets gets more important. This is the index for tracking resistance.
The crystal oscillator refers to a slice (abbreviated as a wafer) from a quartz crystal at a certain azimuth angle, a quartz crystal resonator, which is simply referred to as a quartz crystal or a crystal, and a crystal oscillator; and a crystal element i
