Products

ILSI Quartz or piezo crystal products have piezoelectric properties and are supplied in Surface Mount Device (SMD) thru hole, metal can, and ceramic packaging configurations. Quartz crystals or piezo crystals are the most common type of piezoelectric resonator used today. Crystal products can be supplied at custom and standard frequencies where required with custom parameters such as tight stability and low effective series resistance (ESR), with customer specified pullability.
