The frequency fC is defined as the midpoint between the 3dB frequencies. 2. Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture that is connected to a 50Ω test system with VSWR ≤ 1.2:1. The test fixture L and C are adjusted for minimum insertion loss at the filter center frequency, fC. Note that insertion loss, bandwidth, and passband shape are dependent on the impedance matching component values and quality. 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 = f0 [1 - FTC (T0 - TC)2]. 6. The specifications of this device are based on the test circuit shown above and subject to change or obsolescence without notice. 7. All equipment designs utilizing this product must be approved by the appropriate government agency prior to manufacture or sale. 3. Unless noted otherwise, specifications apply over the entire specified operating temperature range. 8. 4. 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. 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. 9.

Vibration The Filter shall be measured after being applied vibration of amplitude of 1.5mm with 10 to 55Hz bands of vibration frequency to each of 3 perpendicular directions for 1 hour. Lead Pulling Test Weight a long with the direction of lead without any shock 1.0 Kg. 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 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 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, 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 meet the Electronic Characteristics REFLOW SOLDERING TEMPERATURE PROFILE Phone: +86 (10) 5820-3910 SF418 © VANLONG TECHNOLOGY CO., LTD.
