  1. I’m designing a hand-held device for a client, and I’m in need of a membrane switch keypad. One of the requirements is that the keypad be manufactured to withstand moisture. Do you know any companies who specialize in very tough keypads for rigorous environments?
  2. Hello We designed this Snubber Circuit with this varistor in parallel but we have a problem in a small load. Even when the relay is disconnected, a small current is flowing. For example, when connecting a phone charger, the phone screen keeps turning on and off. The varistor is Hongzhi Elec 7D471K The resistor is 2.2 ±5% 1W ±350ppm/°C Axial,3.3x9.2mm Carbon The capacitor is 100nF ±10% 275VAC 10 Through Hole,P=10mm Suppression Capacitors I think the problem is with the capacitor and maybe I need a smaller one to increase the impedance and limit the current flow or schematic problem.
  3. I have a question, there are so many development boards in this world, banana pi, raspberry pi and so on, could you pls tell me more about these boards? What's your opinion?
  4. Hello, Everyone!!! I am Katy Radcliff and new to this forum. I love to repair and rework PCB's, so I hope I will get something new related to PCB's and other electronic things.
  5. Good afternoon~all Please help me out. As the LP3856’s datasheet shows,the inputted current is 3.3V,the outputted current is 1.8V,the referring voltage is 1.216V,. What should I consider about when in the design process? Can I use LP3856 here ? Wishes~
