Thank you very much for your comment.
My PCB consists of a micro-controller and some optocoupler to enable and disable some 24V output switch (10mA). However, my main load is a motor driver which use 2A to biases itself. In my test, I disconnected my motor driver and my circuit just consumes...
Thanks for your comment and swift response.
I put a power connector on my PCB. When I connect the power to it at first glance, because my Cap is empty, it produces a spark at my connector. In addition I am worried about the life time of my component such as my diode bridge and my power supply in...
Hello,
I have a 24V/6A dc power supply. When I apply this power supply to my circuit ( a diode bridge and 470MF capacitor) it produces sparks. I am going to use a NTC (about 10ohm). Based on my space limitation I can't use a relay to bypass this NTC after a second. I am worried about placing...
Dear KlausST,
Thank you for your comment and you useful info. I have heard that my PCB should be checked for EMI/EMC test which my board is not a high-frequency board it just has Ethernet Connection+Max485 communication.
Hello,
I need to know how to protect my circuit from EMC test. My input voltage is 24V(3A) and after a pole diode( for preventing from reverse voltage) and TVS diode it goes to my regulator(MinMax dc-dc). How can I increse my protection?
Hello,
Here the ethernet connector(http://www.kosmodrom.com.ua/pdf/HR911105A.pdf) that I am going to implement in Altium.
I need to know that for plastic connector (phi=3.25) if my configuration is right. (hole size=3.25 , X/Y for round shape=2.5)
Hello,
I designed my board in Altium designer. After checking the DRC I had to change a clearance in my PCB library. Howeve after doing that, updating my schematic librar and schematic, there was nothing to update into PCB window( it means changing a size,clearance, ... in PCB library which...
Hello,
Here is my PCB file. I need to know why P1_1 and U2_1 don't move by changing their room position. In addition by selecting all components again, they don't move.(ROOM name :TCP1)
Thank you.
Thank you so much for your help. Could you help me to design dp83848I?(https://www.ti.com/lit/ds/symlink/dp83848c.pdf)
In the datasheet it doesn't mention the value of these parameters directly.
Thanks
