Components References (Values)

[yalect]

Hi,

I would like to ask you that I want to buy some semiconductors components.

  what best kind or type of Op Amp by looking to its features like bandwidth frequency and voltage do you think and in other hand its price like :

LM741 ,……………..

and

transistors : NPN PNP FET

Bf199, 2n2222………………………………….

Thank to hear from you much values.

Thank you

Check the series of DAve

For example : EEVBlog 1436 - The TOP 5 Jellybean OPAMP's

I used to buy from Alli kits already done  in order to have some legacy references try this kind of Keywords  "50Pcs/box 10 Values Mosfet Transistor Kit IRF3205 IRF640 IRF740 IRF830 IRF840 IRF530 IRF630 IRF820 IRFZ44 IRF9540 IRF820"

But ypu have to chose what you want (high voltage, BJT, MOSFET, ...)

Small signal transistors:  2N2222A, 2N3904, 2N3906
Small signal diodes: 1N914, 1N4148
Power diodes:  1N4001-1N4007 - check datasheet for voltage/current ratings
Op Amps:  Watch Dave's video, referenced above, LM358

Maybe there are other references or values list of Op amp and transistors (FETs, BJT, ....) I based more on frequency range and medium voltage or more.
Thank you
