APPLICATIONS
RKT206 is a quartz crystal resonator used to sense temperature changes. The crystal is designed for precision elec tronic thermometers and temperature controllers for conversion of temperature to frequency.
FEATURES
- High shock and vibration characteristics - Miniature size - Wide temperature range (-50…+100 °C) - Low power consumption - Suitable for DTCXO and temperature test equipment ELECTRICAL CHARACTERISTICS (at temperature 37 °C) / OPERATING CONDITIONS PARAMETERS SPECIFICATIONS AND REMARKS UNITS Electrical characteristics at temperature 37 °C Frequency range, fO 32.000…36.000 kHz Frequency Tolerance typ./max., ∆f/fO ± 150 ppm Resonance resistance typ./max., Rr 75/95 k Ω Static Capacitance typ., CO 1.3 ± 0.2 pF Capacitance ratio r 870 Drive level max., DL 1.0 µW Insulation resistance min. 500 M Ω Motional characteristics Frequency vs. Temperature fT=fO +A1*(T-TO) +A2*(T-TO)2, There: fT – crystal frequency at temperature T (°C), fO – crystal frequency at reference temperature T0 (°C), TO – reference temperature (°C). For higher accuracy fT can be represented by a third order polynomial as follow: fT=fO +A1*(T-TO)+A2*(T-TO)2+A3*(T-TO)3 1st order temperature coefficient A1* -1.811 ± 0.06 K -1 2nd order temperature coefficient A2* -0.0028 ± 0.0001 K -2 3rd order temperature coefficient A3* 7.6 * 10-6 K -3 Aging first year/10 years max. ± 5 / ± 10 ppm Thermal time constant in liquid τ 5 sec Operation conditions Operating temperature, TOPR (typ/max) -50…+100 / -269…+125 °C Storage temperature, TSTR -55…+85 °C Shock resistance, ∆f/f0 Drop test 3 times on hard wooden board, height 100cm 5000g., 0.2 ms / ±5 ppm max. ppm Vibration resistance, ∆f/f0 10g / 10-2000 Hz, 8 hours / ±5 PPM max. ppm *A1, A2 and A3 coefficients can be changed on request.
