Note 1: An electrical shield by metal shied plate on the IC package should be recommend able in order to
prevent the device from the high electric fieldstress applied for continuous reliable operation.
Note 2: The product numbers and specifications of the resonators
by Murata Manufacturing Co., Ltd. are subject to change.
