I received the transistors and made a circuit board. You generally get a selection of various transistors, and considering the overhead the store has, they’re actually a decent bargain. Could the 2n replace the 2n? Could it be the capacitors? Mar 10, 1.

What you might consider doing is laying out your board so that you could put three or four of the T1’s in parallel, with fairly low-value resistors in series with the collectors and bases. Yes, my password is: Even 2h2905 I had owned it for over 20 years, my local RS store exchanged it for a new one, no questions asked – it was obvious that it had not been installed.

I beleive I have used them both before for the circuit I am trying to make, but I just want to double check that they will work. Interfaces for Computer-Controlled Test Systems A short introduction to some of the more popular interfaces used to connect test instruments to computers.


They are ICM, heres their page on them. Mar 11, 5.

2N Transistor – 2N PNP Switching Transistor – Robomart

I will try the alternate resistors next time I can get to a radioshack. No, create an account now. Mar 19, You May Also Like: You DID use two diodes in series for 2n9205 two D1’s, right? Jan 18, 6, 1, They are rated for quite a bit more power than 2N’s and 2N’s. If the SMT 2n’s are inadequate I will post back.

I used the toner method and it worked prefect. The Black Friday Breakdown You’ve been waiting all year to get your hands on some hot new components, and now’s the best time! Expect resistance sic if you n22905 soldered leads to it.

Which multiplexor to use? The 2N clearly says 2N, not “like” or “similar to” 2N Mar 11, 8. Since the two transistors are wired differently to their respective controller triggers, I was simply questioning whether there was a typo in the schematic. I will try it with the 2n You might try increasing R4 to and 2n295 to Ohms. Mar 18, It looks like RS has fallen even another step.


That’s part of the fun. I’ve also found ‘s, etc in the assortment. PNP small-signal type amplifying transistor, similar to 2N When using the circuit the right trigger stopped working but the left trigger was fine. All you have to do is satisfy the parameters of the load 2b2905 transistor drives.

Their 15 pack of N22905 transistors is labeled as 2n, but they all have different codes written on them. The RS resistors have been extremely consistent in their values over the years. Look for the current carefully.

Transistor, Bipolar, PNP, 2N2905

The 1uF is 35v and the 0. Which Equation to use? If the schematic is correct and all the wiring is correct, then why doesn’t it work?

The transistors I have are sot, I have the correct wires going to the correct places on the transistors base, collector, emitter. Since the left one works with the emitter to the trigger, I applied Sutton’s Law and proposed that perhaps the emitter on the right transistor should also go to the trigger.
