  • Check your connection circuits before turning on the PD.
  • Mind the PD polarity..
  • DO NOT connect the PD to the multimeter. Soldering:
  • Do avoid overheating of the PD
  • Do avoid electrostatic discharge (ESD)
  • Do avoid mechanical stress, shock, and vibration
  • Do only use non-corrosive flux
  • Do not apply current to the PD until it has cooled down to room temperature after soldering Static Electricity: PDs are sensitive to electrostatic discharge (ESD) . Precautions against ESD must be taken when handling or operating these PDs. Surge voltage or electrostatic discharge can result in complete failure of the device. © All Rights Reserved The above specifications are for reference purpose only and subjected to change without prior notice EPD-525-0-1.4 TO-18
