Part Number SFM-8527-03 2. Dimension Drawing (Unit: mm) SFM-TERMINAL VERSION Solder paste thickness is not below 0.3mm RECOMMENDED SMD FOOT PATTERN 3.Specification No. Item Specification 3-1 Min. Sound Pressure Level 80dB/2730Hz/3V /10cm 3-2 Rated Voltage 3V 3-3 Operating Voltage 2~5V 3-4 Max. Consumption (At 3VDC) 80mA/2730Hz/6VP-P square wave 3-5 Resonant Frequency 2730Hz 3-6 Coil Resistance 24±8Ω 3-7 Coil Impedance 60Ω 3-8 Operating Temperature -30~+85℃ 3-9 Storage Temperature -30~+85℃ 3-10 Case Material/Color PPS/Black 3-11 Weight 1.0g 3-12 Pin Strength More than 10N NOTES： 1、Value applying rated voltage(resonant frequency,1/2duty,square wave) 2、Test should be made under the conditions of room temperature (20±10℃), normal humidity (60±20%) and normal atmospheric pressure. In this case, however, that the judgment is questionable, the test conditions are to be changed to room temperature 20±2℃, relative humidity 60~70% and normal atmospheric pressure Ningbo East Electronics Limited 2/6 4.Typical Frequency Response Curve Note: Input Voltage 3V Distance 10 cm 5. Reliability Test No. Item Method of Test 5-1 Operating Temperature -30~+85℃ 5-2 Storage in high temperature Storage in +85℃ test box 96 hours then exposed to the room temperature for 2 hours 5-3 Storage in low temperature Storage in -30℃ test box 96 hours then exposed to the room temperature for 2 hours 5-4 Life test in the room Operate the product continuously 5 seconds on 5 seconds off temperature 300 hours at rated voltage 5-5 Temperature / humidity cycle test Storage in +40℃, 93±3%RH test box 96 hours then exposed to the room temperature for 2 hours 5-6 Temperature (high and low) cycle test Conduct the test for 5 cycles without applying power then expose to the room temperature for 2 hours.(See Figure 5-6) Tolerance after Testing Sound pressure level initial value ±10dB Max. consumption value ±20% Conduct the test for the directions of X Y and Z for 0.5 hour Ningbo East Electronics Limited 3/6 5-7 5-8 5-9 5-10 Vibration test each (total 1.5 hours). To-and Fri sweep time(from 10 to 55Hz and then 55 to 10) under single amplitude of 0.75mm is 3 minute, then expose to the room temperature for 2 hours Drop test Drop a product naturally from the height of 700mm onto the surface of 100mm thick wooden board. Two directions: upper and side of the product are to be applied for this drop test once respectively Reflow soldering heat resistance a) Pre-heating conditions shall be +140℃ to 160℃ for 160 to 200 seconds. (See Figure5-9) b) Heating conditions shall be within 60 seconds at +200℃ min., but peak temperature shall be lower than +260℃. (See Figure 5-9) Test of soldering Dip the connecting pins in soldering at 255±5℃ for 3±0.5 seconds Solder shall be attached around over 95% of the dipped portion NOTE: The pins are allowed to deform after drop test.
