Overview
The U Series is a range of crystal units designed for use in microcontrollers, processors, and consumer electronics.
Key Features
The U Series features a frequency range of 3.579545 MHz to 125.0 MHz, with a tolerance of ±10 ppm at 25°C. The operating temperature range is -40°C to +85°C, with a storage temperature range of -55°C to +125°C.
The series has a low drive level of 1 μW max, and an aging rate of ±5 ppm/year max.
ESR Characteristics
The U Series has a load capacitance of 10 to 32 pF, and an ESR that varies depending on the frequency range, as shown in the table:
Frequency Range (MHz)
3.579545 to 3.9: ESR (Ω) 180 Max
4.0 to 4.9: ESR (Ω) 100 Max
5.0 to 5.9: ESR (Ω) 80 Max
…and so on.
