Electrical Specification of 447MHzSAW Resonator

Table1
Electronic Characteristics of 447MHz SAW Resonator

Environmental Characteristics of 447MHzSAW Resonator 
1. High temperature exposure
Placing the 447MHz SAW resonatorat 85 ℃ for sixteen hoursand then releasing the filter into a room with normal temperatureconditions for twenty-four hours prior to the measurement, it shall fulfil thespecifications in table 1
2. Low temperature exposure
Placing the 447MHz SAW resonatorat -40 ℃ for sixteen hoursand then releasing the device into a room with normal temperatureconditions for twenty-four hours prior to the measurement, it shall fulfil thespecifications in table 1
3. Temperature cycling
The 447MHzSAW resonator must be in a place with low temperature, -40 ℃ for 30 minutes, following by a higher temperature of 85℃ for30 minutes. When the device is released into a room with normal temperatureconditions for twenty-four hours prior to the measurement,it shall meet the specifications in table 1.
4. Resistance tosolder heat
If the 447MHz SAW resonator terminals are immerse nocloser than 1.5 mm intothe solder bath at 260℃ ±10℃ for10±one second and then release the device into a room with normaltemperature conditions forfour hours, it shall meet the specifications in table 1.
5. 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 withnew solder; the 447MHzSAW resonator shall meet the specifications intable 1.
6. Mechanicalshock
Drop the 447MHzSAW resonator randomly onto the concrete floor from a height of 1 m three times. The device shall fulfil thespecifications in table 1.
7. Vibration
Subject the device to vibration for two hours each in x, y and z axeswith amplitude of 1.5 mm at 10 to 55 Hz. The deviceshall fulfil the specifications in table 1.

Remarksfor 447MHz SAW Resonator Usage
1. Static voltage
Please avoid static voltagebetween signal load and ground, it may cause deteriorationor destruction of the SAW resonator components.
2. Ultrasonic cleaning
Please avoid ultrasonic cleaning, it may cause deterioration ordestruction of the SAW resonator components.
3. Soldering
Please avoid soldering different parts of the SAWresonator components, just leads may be soldered.
