Notes:

The center frequency, f_C, is measured at the minimum IL point with

the resonator in the 50Ω test system.

Derived mathematically from one or more of the following directly

measured parameters: f_C, IL, 3 dB bandwidth, f_Cversus T_C, and C₀.

Unless noted otherwise, case temperature T_C= +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 f_Cwith 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.

Turnover temperature, T₀, is the temperature of maximum (or

turnover) frequency, f₀. The nominal frequency at any case

temperature, T_C, may be calculated from: f = f₀[1 - FTC (T₀- T_C)²].

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 C₀is the measured static (nonmotional) capacitance

between Pin1 and Pin2. The measurement includes case parasitic

capacitance.
