Hi Frayn just as zappedagain said ,it is normally off as you can see the broken line in the symbol in the datasheet(if you got),that means we need to add a voltage between the gate and the source,so that the drain and source would be connected ,which would make the circuit work. This is why it...

Last time I post a thread which is titled "just tell it out". I said something about myself,the so many kind advices that I recieved make me be couraged to ask this question. I am a component engineer in a factory,and our products is electronic such as the CCTV, microphone,fire alarm.we have our...

waskillywabbit,Thanks ,it sounds something like the "Matrix" ;) csd72,also thanks for your kind prize, :) Yes,I should have checked before submitting this post,I forgot,and I would never make it happen again.But I do admit I am NOT professional,that is the reason I log on here,I hope for more...

geekEE ,thanks a gain for your ebullience. here is my company,the ERP is the very SAP,and the logistic give me the SAP number and I can find out in SAP what the component is ,the SAP is open to all the staff here.There I know it is a transformer,and usually for a transformer we would have a...

Hello dears Last summer,I gratuated from college majoring in Electronic Sience and Technology,at that time we classmates acronymed it "EST" and we said "Be EST",then we become the "BEST",at that time we did think we were always the best(how innocent as I think now),we studied the semiconductor...

For me 'management type' professions such as accounting and marketing is just like the orientation for a a car while the engineering is the the motivity,both are necessary. But for a boss ,less speed or wrong orientation,which would be prefered? undoubtedly,in a company,prompted engineer would...

JsTyLz, you seems a little pessimistic,you said the job of dream never exists,I guess that must be related to your own experience while most of time the conclusion from someone`s experience would not always be fit for others, to say that we need to know how to define a "job of dream", in my...

Thanks macgyvers2000& geekEE actually the logistic dep. asked me the exact value of some transformer according to the part number they gave me , while here now in ENG-TIP ,I just want to know some further knowledge about the transformer voltage. as far as I know ,normally the transformer is...

Oh ,SoooooOOOOooo quick reply that I never expected . Thanks a million! ^_^ but here in my company,the Logistic department just want one voltage parameter to fill in the custom file to ship out. They would not care what is the the voltage (which they just want the value with the unit "V" )...

Hello Any expert on transformer: if I just want the default voltage for a transformer which exact voltage does it mean to ? since there as I know many voltage parameter for a transformer. Thanks. We are always available to help each other.

Thanks ,IRStuff. I `v done that ,and found many websites, and now I just need a recommedation to just favourate most-used and all-sided one. because I thought it make my future work more convenient. We are always available to help each other.

new friend here ,first face . I would ask for where I can search the IC datasheet including all the manufacturers. Thanks in advance.
