CX3HSM CRYSTAL 18 kHz to 600 kHz Low Profile Surface Mount Quartz Crystal for Series Oscillators DESCRIPTION The CX3HSM quartz crystals are leadless devices designed for surface mounting on printed circuit boards or hybrid substrates. These miniature crystals are intended to be used in Series oscillators. They are hermetically sealed in a rugged, miniature ceramic package. They are manufactured using the STATEKdeveloped photolithographic process, and were designed utilizing the experience acquired by producing millions of crystals for industrial, commercial, military and medical applications. Maximum process temperature should not exceed 260O C. actual size side view Glass Lid Shown PACKAGE DIMENSIONS D TOP A BOTTOM D FEATURES Miniature tuning fork design D High shock resistance E B Designed for low power applications C TYP.
