NS = Not Specified

Note:

The measurement includes case parasitic capacitance.

The frequency f_cis the frequency of minimum IL with the resonator

in the specified test fixture in a 50Ω test system with VSWR ≤ 1.2:1.

Derived mathematically from one or more of the following directly

measured parameters: f_c, IL, 3 dB bandwidth, f_Cversus T_C, and Co.

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.

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 = f_o[1 - FTC (T_O- 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 C_Ois the measured static (nonmotional) capacitance

between input terminal and ground or output terminal and ground.
