The center frequency, fC, is measured at the minimum IL point with the resonator in the 50Ω test system. 6. Derived mathematically from one or more of the following directly measured parameters: fC, IL, 3 dB bandwidth, fC versus TC, and C0. 7. The specifications of this device are based on the test circuit shown above and subject to change or obsolescence without notice. 8. 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 = f0 [1 - FTC (T0 - TC)2]. Typically, equipment utilizing this device requires emissions testing and government approval, which is the responsibility of the equipment manufacturer. 9. This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance C0 is the measured static (nonmotional) capacitance between Pin1 and Pin2. The measurement includes case parasitic 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. 10.

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. 5. capacitance. Phone: +86 (10) 5820-3910 SR433T © VANLONG TECHNOLOGY CO., LTD.

Vibration The Filter shall be measured after being applied vibration of amplitude of 1.5mm with 10Hz to 55Hz bands of vibration frequency to each of 3 perpendicular directions for 1 hour. Lead Pulling Test A weight of 3kg is pulled towards an axis of each terminal for 10 seconds. Lead bending Test Lead shall be subject to withstand against 90 bending at its stem. This operation shall be done toward both directions. Resistance to Soldering Heat Lead terminals are immersed up to 1.5mm from the Filter’s body in solder bath of 270°C ± 10°C for 10 ± 1 seconds, and then the Filter shall be measured after being placed in natural condition for 2 hour. Solderability Lead terminals are immersed in resin for 5 seconds and then immersed in soldering bath of 270°C ± 10°C for 2 ± 0.5 seconds. High Temperature Storage After being placed in a chamber with +85°C ± 2°C for 96 ± 4 hours and then being placed in natural condition for 2 hour. The Filter shall be measured. Low Temperature Storage After being placed in a chamber with -40°C ± 2°C for 96 ± 4 hours and then being placed in natural condition for 2 hour. The Filter shall be measured. Humidity After being placed in a chamber with 90 to 95% R.H. at +40°C ± 2°C for 96 ± 4 hours and then being placed in natural condition for 2 hour. The Filter shall be measured. Heat Shock After being kept at room temperature, the Filter shall be placed at temperature of -40°C for 30 minutes, and then the Filter shall be immediately placed at temperature of 85°C, after 30 minutes at temperature of 85°C, the Filter shall be returned to -40°C again. After 5 times above cycles, the Filter shall be returned to room temperature, after 2 hour in natural condition, the Filter shall be measured. No visible damage and the measured values shall remain the Electronic Characteristics after tests. REFLOW SOLDERING TEMPERATURE PROFILE Phone: +86 (10) 5820-3910 SR433T © VANLONG TECHNOLOGY CO., LTD.
