CTS TF Series Tuning Fork Crystals

CTS Electronic Components announces development of the TF32 and TF20 series tuning fork crystals. These crystals are housed in a ceramic 2-pad surface mount package, 3.2 mm x 1.5 mm and 2.0 mm x 1.2 mm respectively. Commonly referred to as “watch crystals”, these tuning fork designs are suitable for applications that include clock timers, wireless communications, test and measurement, portable equipment, FPGAs, PDAs, mobile phone and notebooks.

Starting with a 32.768 kHz frequency, the TF Series devices are optimized for a standard 12.5 pF load capacitance. The standard frequency tolerance at +25°C is ±20 ppm. With a standard operating temperature range of -40°C to +85°C, the TF Series provides a temperature coefficient of -0.030 ppm/°C.

Additional features include: turnover temperature range of +20°C to +30°C, series resistance of 70k Ohms maximum, insulation resistance of 500M Ohms at +100 Vdc, and storage temperature range at -55°C to +125°C. Aging is ±3 ppm per year.
