Dear All,
I am quite new to the field of EMI testing,
What are basics steps and design rules to be followed to make a PCB to withstand EMI requirements.
How common mode choke act as emi filters.
Thanks in advance
Thanks for your reply,
Also please I have checked this link

Dear Sir,
In my SMPS I am using 470uF, 35V capacitor, the output voltage is 24Vdc.
This 24Vdc output is given to the load of 2.5W through this capacitor.
Input voltage of this SMPS is 72Vdc.
I want to know after switching off this SMPS, what will be the time taken by this electrolytic...
Dear All,
I am working with the sensor which has the voltage step of 0.5mV,
For the 12 bit ADC with the reference voltage of 5 V, it can measure only 1.2mV,
I required the microcontroller with the inbuilt 14 or 16 bit ADC
What can the best solution for this issue, please post your valuable...
Hi all,
Can any one help me to find the collector current Ic & power dissipation of the PNP transistor Q3 given in my circuit.
Kindly give me your feedback & your guidance , it will be very helpful for me.
Hi all,
I am using zener diode in my circuit, basically I am using this circuit as a water level sensor. Please find the attached file for the circuit diagram.
This 10V/3W zener is supplied 24Vdc, then the 10 V is drawn by a sensor of 120 ohms & by a resistor of 47 ohms.
Thus the current...
Dear All,
I am using PIC16F630 microcontroller in my project, I have assembled the PCB and did thermal cycling test( kept the control unit assembly at - 40 C for the time period of 24 hrs) . After the completing the thermal cycling I have conducted the functional test but the I had problem with...
Dear sir,
I used KDS4.000MHz crystal and followed our steps, but the hardware did not respond, should I have to do any changes in the program ?
I am using picstart plus programmer to program the IC, during the configuration of the IC, in the oscillator tab I have selected "XT". Is this enough...
Thanks for your reply,
At present I am using hitech C compiler only.
In this circuit I am using 4Mhz internal clock, due to this I am getting some errors in the timing. So I have decided to go for the external clock.So for this application which method will give better solution to me.
Thanks...
Dear Sir,
I want to connect external oscillator to my PIC16F630 IC, can any one guide me how to interface how to interface it in the hardware and should it required any changes in the software.
I am quite new to this electronic world, your reply will be very valuable for me.
thanks in advance,,
