CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.
Notes:
1. Lifetime (10 year) frequency aging.
2. The center frequency, f_C, is measured at the minimum insertion loss
point, IL_MIN, with the resonator in the 50 W test system (VSWR ≤
1.2:1). The shunt inductance, L_TEST, is tuned for parallel resonance
with C_O at f_C.
3. One or more of the following United States patents apply: 4,454,488
and 4,616,197.
4. Typically, equipment utilizing this device requires emissions testing
and government approval, which is the responsibility of the equipment
manufacturer.
5. Unless noted otherwise, case temperature T_C = +25°C±2°C.
6. The design, manufacturing process, and specifications of this device
are subject to change without notice.
7. Derived mathematically from one or more of the following directly
measured parameters: f_C, IL, 3 dB bandwidth, f_C versus T_C, and C_O.
8. Turnover temperature, T_O, is the temperature of maximum (or
turnover) frequency, f_O. The nominal frequency at any case
temperature, T_C, may be calculated from: f = f_O [1 - FTC (T_O -T_C)²].
9. This equivalent RLC model approximates resonator performance near
the resonant frequency and is provided for reference only. The
capacitance C_O is the static (nonmotional) capacitance between Pin 1
and Pin 2 measured at low frequency (10 MHz) with a capacitance
meter. The measurement includes parasitic capacitance with a floating
case. Case parasitic capacitance is approximately 0.25pF. Transducer
parallel capacitance can be calculated as: C_P ª C_O - 0.25 pF.
