Note:  
The measurement includes case parasitic capacitance.  
1.  
The frequency fc is the frequency of minimum IL with the resonator  
in the specified test fixture in a 50Ω test system with VSWR ≤ 1.2:1.  
6.  
7.  
8.  
Derived mathematically from one or more of the following directly  
measured parameters: fc, IL, 3 dB bandwidth, fC versus TC, and Co.  
2.  
3.  
Unless noted otherwise, case temperature TC = +25°C±2°C.  
The specifications of this device are based on the test circuit shown  
above and subject to change or obsolescence without notice.  
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.  
Typically, equipment utilizing this device requires emissions testing  
and government approval, which is the responsibility of the  
equipment manufacturer.  
4.  
5.  
Turnover temperature, T0, is the temperature of maximum (or  
turnover) frequency, f0. The nominal frequency at any case  
temperature, TC, may be calculated from: f = fo [1 - FTC (TO - TC)2].  
9.  
Our liability is only assumed for the Surface Acoustic Wave (SAW)  
component(s) per se, not for applications, processes and circuits  
implemented within components or assemblies.  
This equivalent RLC model approximates resonator performance  
near the resonant frequency and is provided for reference only. The  
capacitance CO is the measured static (nonmotional) capacitance  
between input terminal and ground or output terminal and ground.
