Electrical Specification of 315AS4SAW Filter

Electronic Characteristics of 315AS4 SAW Filter

EnvironmentalCharacteristics of 315AS4 SAW Filter
1.Temperature cycling
The 315AS4 SAW filter must be in a place with lowtemperature, -40 ℃ for thirty minutes, following by ahigh temperature of 25℃ for five minutes andthen a higher temperature of 85℃ for thirty minutes.When the device is released into a room with normal temperatureconditions for one or two hours prior to the measurement,it shall meet the specifications in table 1.
2. Resistance to solder heat
Submerge the 315AS4SAW filter terminals into the solder bath at 260℃ ±5℃ for 10 ± 1 second. Then release the device into a room with normal temperatureconditions for four 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 withnew solder; the 315AS4SAW filter shall meet the specifications in table 1.
4. Mechanical shock
Drop the 315AS4 SAWfilter randomly onto the concrete floor from a height of 1 m three times. The filter shall fulfil thespecifications in table 1.
5. Vibration
Subject the device to vibration for two hours each in x, y and z axes withamplitude of 1.5 mm at 10 to 55 Hz. The filter shall fulfil thespecifications in table 1.

Remarks for 315AS4SAW Filter Usage
1. Static voltage
Please avoid static voltagebetween signal load and ground, it may cause deteriorationor destruction of the SAW filter components.
2. Ultrasonic cleaning
Please avoid ultrasonic cleaning, it may cause deterioration ordestruction of the SAW filter components.
3. Soldering
Please avoid soldering different parts of the SAW filter components, just leads may be soldered.
