CRYSTAL OSCILLATOR

摘要

PROBLEM TO BE SOLVED: To provide a surface mount crystal oscillator having a good crashworthiness and preventing from fluctuations of a frequency before and after dropping impact. SOLUTION: In the crystal oscillator, which is composed of a crystal chip fixed its both side end portions having an extension electrode extended from an exciting electrode on a base end surface of a recessed container body by a conductive adhesive, and is sealed its opening face of the container body by a cover, the ratio d/L of the distance d between the crystal chip and the cover to the length L of the crystal chip is designed to be set as 0
