iCAUTION: Electrostatic Sensitive Device. Observe precautions for handling!

The centre frequency, fC, is measured at the minimum IL point with the resonator in the 50 Ω test system.

Unless noted otherwise, case temperature TC = +25°C±2°C.

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.

Turnover temperature, T0, is the temperature of maximum (or turnover) frequency, f 0. The nominal frequency at any

case temperature, TC, may be calculated from: f = f0 [1 - FTC (T0 - TC)

2].

This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for

reference only. The capacitance C0 is the measured static (non-motional) capacitance between the two terminals.

The measurement includes case parasitic capacitance.

Derived mathematically from one or more of the following directly measured parameters: f C, IL, 3 dB bandwidth, fC

versus TC, and C0.

The specifications of this device are based on the test circuit shown above and subject to change or obsolescence

without notice.

Typically, equipment utilizing this device requires emissions testing and government approval, which is the

responsibility of the equipment manufacturer.

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.
