Since the two transistors are wired differently to their respective controller triggers, 2n9205 was simply questioning whether there was a typo in the schematic. Posted by clickman in forum: I have no idea whether the triggers are wired in series or parallel, which could make a difference.

Mar 19, This does not include pots. Could it be the capacitors? 2b2905 multiplexor to use? When using the circuit the right trigger stopped working but the left trigger was fine. Posted by LucasSaavedra in forum: Yes, my 2n29055 is: Discussion in ‘ General Electronics Chat ‘ started by nevermindMar 10, Bottom line, at this point, I don’t know that I would trust the RS product to be what it is labeled.

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.

Dec 4, 14 0. 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. I made 2n22905 mod with both triggers, then one that only used T2, then one that only used T1. It looks like RS has fallen even another step. Thanks for the help!


n22905 Posted by picstudent in forum: If you clip and bend TO leads, you can stick them on a set of smt pads. Which SMT transistors to use? Mar 11, 4. Apr 20, 15, I received the transistors and made a circuit board.

Mar 11, 7.

Mar 10, 1. I took the battery out of my controller and it worked again for a few minutes and stopped.

Interfaces for Computer-Controlled Test Systems A short introduction to some of the more popular interfaces used to connect test instruments to computers.

The PNP link says, “Your source for transistors. I came across an ebay auction for 2n and 2n in SOT And would both 2n and 2n work as well as 2n?

2N BIPOLAR TRANSISTOR, PNP, V, TO Package: : Industrial & Scientific

Which battery to use? We’ve rounded up sites offering discounts and perks from today through Monday. The schematic works, but after a few minutes it stops working but works when power is disconnected then reconnected.

Posted by woolerland in forum: Mar 11, 8. I will try it with the 2n They are rated for quite a bit more power than 2N’s and 2N’s.

If the transistor will handle the voltage and current, then many substitutes are possible.

Mar 10, 3. 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.

I didn’t look that closely at the parts list to notice the difference. Not planning ahead for such contingincies might find you creating a whole new board. PNP small-signal type amplifying transistor, similar 2n905 2N The transistors I have are sot, I have the correct wires going to the correct places on the transistors base, collector, emitter.

Their 15 pack of PNP transistors is labeled as 2n, but they all have different codes written on them.

2N2905 Datasheet, Equivalent, Cross Reference Search

2b2905 I’ve also found ‘s, etc in the assortment. I am assuming they are basically paralleled inputs to the You generally get a selection of various transistors, and considering the overhead the store has, they’re actually a decent bargain.

I’ve never had to pay a shipping charge from RS, only “schlepping charge”; aka the cost of getting there and back One has to inspect the transistors in the assortment, look 22n905 the datasheets, and test them. And could 2n replace 2n?

If the schematic is correct and all the wiring is correct, then why doesn’t it work? It looks to me like the E and C connections to the right trigger may be reversed 2n2950 the schematic.
