AT-Cut SMD Crystals
NDK (Nihon Dempa Kogyo Co., Ltd.) announces its NX8045GB series, a 4 MHz thickness shear vibration mode (AT-cut) SMD crystal unit in a 8.0ࡪ.5ࡧ.8 mm package. The low frequency operation keeps the power consumption low (drive level 50 µW) and it can be applied with existing IC designs. It is available in a frequency range of 4 to 40 MHz with a frequency tolerance of ± 30 ppm at an ambient temperature of +25° C. It is suitable for automotive applications with an operating temperature range of -40 to +125° C while delivering superior environmental performance including high heat, vibration and impact resistance. The device meets the requirements for re-flow profiling using lead-free solder, and it is RoHS compliant.
