Part Number MT-520 2. Dimension Drawing (Unit: mm) 3.Specification No. Item Specification 3-1 Min. Sound Pressure Level 98dB/2~4 kHz /18Vp-p Square Wave /300cm 3-2 Allowable Input Voltage 60Vp-p 3-3 Capacitance 140±30%nF(At 120Hz) 3-4 Resonant Frequency 2~4kHz 3-5 Operating Temperature -40~+85ºC 3-6 Case Material /Color PA6/Black 3-7 Weight 15.9g 3-8 Pin Strength More than 10N NOTES： 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 East Electronics 2/5 4.Typical Frequency Response Curve Note: Input Voltage 2.83VRMS Sine Wave Distance 50cm 5. Reliability Test No. Item 5-1 Operating Temperature -40~+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 -40℃ 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 temperature off 96 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) Vibration test Conduct the test for the directions of X Y and Z for 0.5 hour each (total 1.5 hours). To-and Fri sweep time(from 10 to 55Hz and then 55 to 10Hz) under single amplitude of 0.75mm is 3 minute, then expose to the room temperature for 2 hours 5-7 East Electronics Method of Test Tolerance after Testing Sound pressure level initial value ±10dB Capacitance value ±20% 3/5 5-8 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 5-9 Soldering heat resistance test Dip the connecting pins in soldering at 260±5℃ for 10±1 seconds Test of soldering Dip the connecting pins in soldering at 230±5℃ for 3±0.5 seconds 5-10 Solder shall be attached around over 95% of the dipped portion NOTE: The pins are allowed to deform after drop test.
