Environmental Characteristics of 433MHz SAW Resonator
1. Temperature cycling
The 433MHz SAW resonator must be in a place with low temperature, -40 ℃ for thirty minutes, following by a high temperature of 25℃ for five minutes and then a higher temperature of 85℃ for 30 minutes. When the device is released into a room with normal temperature conditions for 1 to 2 hours prior to the measurement, it shall meet the specifications in table 1.
2. Resistance to solder heat
Submerge the 433MHz SAW resonator terminals into the solder bath at 260℃ ±5℃ for 10 ± 1 second. Then release the device into a room with normal temperature conditions for 4 hours, it shall meet the specifications in table 1.
3. Solderability
Submerge the device terminals into the solder bath at 245℃ ±5℃ for five seconds. More than 95% area of the soldering pad must be covered with new solder; the 433MHz SAW resonator shall meet the specifications in table 1.
4. Mechanical shock
Drop the 433MHz SAW resonator randomly onto the concrete floor from a height of 1 m three times. The filter shall fulfil the specifications in table 1.
5. Vibration
Subject the device to vibration for two hours each in x, y and z axes with amplitude of 1.5 mm at 10 to 55 Hz. The filter shall fulfil the specifications in table 1.

Remarks for 433MHz SAW Resonator
