1. Unless noted otherwise, case temperature TC = +25°C±2°C.
2. The center frequency, fC, is measured at the minimum insertion loss point with the resonator in the 50Ω test system.
3. Frequency aging is the change in fC with time and is specified at +65°C or less. Aging may exceed the specification for
prolonged temperatures above +65°C. Typically, aging is greatest the first year after manufacture, decreasing in
subsequent years.
4. Turnover temperature, TO, is the temperature of maximum (or turnover) frequency, fO. The nominal frequency at any
case temperature, TC, may be calculated from: f = fO [1 - FTC (TO - TC)2].
5. This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for
reference only. The capacitance CO is the static capacitance between the two terminals measured at low frequency
(10MHz) with a capacitance meter. The measurement includes case parasitic capacitance.

Requirements: The SAW resonator shall remain within the electrical specifications after tests.
Remarks
SAW devices should not be used in any type of fluid such as water, oil, organic solvent, etc.
Be certain not to apply voltage exceeding the rated voltage of components.
Do not operate outside the recommended operating temperature range of components.
Sudden change of temperature shall be avoided, deterioration of the characteristics can occur.
Be careful of soldering temperature and duration of components when soldering.
Do not place soldering iron on the body of components.
Be careful not to subject the terminals or leads of components to excessive force.
SAW devices are electrostatic sensitive. Please avoid static voltage during operation and storage.
Ultrasonic cleaning shall be avoided. Ultrasonic vibration may cause destruction of components.
