shankbond said:does any one knows what does it mean?
IN4001
thank you
shankbond said:actually i needed to know about the meaning of each letter
well my friend i dont think so ,ur answer tells me the specification of the device but doesnt tell me the meaning of each letter .ericgibbs said:Do the links I posted answer your question.?
shankbond said:guys i tried my best but was unable to findout why this 555 timer is put into this circuit
the ckt. shown here is a controlling of stepper motor through PC along with an IR ckt mounted on the stepper motor.
If the IR circuit is the Emitter shown near the 555, then if the IR emitter and photodiode connected to the 555 and the motor is controlling the light path between the IR emitter and the photodiode..
Then
The photo diode controls the input the 55 which controls the relay on pin3
thank you

if u know the answer please tell me the solution
1N4001 is a little like shankbond. It's how you spell the diode's name.shankbond said:well my friend i dont think so ,ur answer tells me the specification of the device but doesnt tell me the meaning of each letter .
if u know the answer please tell me the solution
The 1N indicates a diode. The rest of the numbers are arbitrary and have no meaning other than to designate a particular diode.shankbond said:well my friend i dont think so ,ur answer tells me the specification of the device but doesnt tell me the meaning of each letter .
Papabravo said:Gee. I thought the "1N" stood for one region of N-type semiconductor. The prefix for trnasistors, "2N", meant that there were two regions of N-type semiconductor. That's what the GV (grizzled veteran) told me when I was a young'un. I never had a reason to challenge his version of events. Is it possible he was telling a whopper?
As I recall, the early germanium trannies were PNPs. The only "2N" one I can think of offhand is 2N404. I don't know if the 2N prefix came before the introduction of NPNs or not, but if so, it would pretty much kill that explanation.Papabravo said:Gee.

sorry ,but i made itericgibbs said:Its a very poor drawing, where is it from.?
