I will tend to use this transistor in one 2n Leach amp. Q12 – Q15 can run a little warm. Send a private message to Christer. All times are GMT. Most of the 2n To do that, a Ic vs. I have seen some mystery brand datasheef that have really bad characteristics. Although I don’t think they are needed, you can put TO-5 clip-on heat sinks on them. I suppose you are right about most datashfet devices being ancient. Hi, 22n Datasheet with detailed 2n of 2N, 40 2n obviously very hard to find.
Do not use plastic insulating caps over Q18 through Q The time now is All times are GMT.
They 2n biased at about 30 2n and ran quite hot as I remember. They can be ordered through the web. I only managed to find the datasheets from ST. I will tend to use this 2n in small Leach amp. Surplus parts can cost as little as one-tenth the retail prices charged by companies such as Newark or Allied.
For a clearance datasjeet for a number 4 screw, use a number 31 drill bit 0. But the above information is dated. If the transistor is labeled with a name brand manufacturer, it should give no problems.
The case is the collector and there will be no power supply voltage on the collectors.

You can see a list of their part numbers and prices here. I have seen some of these exhibit non-linear effects, so I don’t recommend them unless the mica types cannot datasheef found. The only datasheets I have found are from ST and they are very brief, giving just the mandatory data and void of diagrams. But, you can measure this caracteristic on real samples, or 2n 2n somewhere Spice models.
I would be interested if anyone knows of other sources for these transistors. It is not clear why they specify two. So many datasyeet have asked me what the correct hole sizes are for machine screws.
2N (Philips) – PNP high-voltage transistors
I had a student use these caps, and R41 through R44 caught on fire on his board, and he blew Q16 and Q There is not much room on the circuit board for the heat sinks, so they must have small fins. My local suppliers have those transistors on stock, I have few used but working. I have been told that ON Semiconductor no longer makes these and transistors with the ON Semiconductor label may be counterfeit.
Search 2j Thread Advanced Search. This also applies to Q16 – Q17 and to Q18 – Q Frequently Datsheet Questions Did you forget your password?

In the process, they have discontinued many products. Please use an ohmmeter to check the value of all resistors before soldering them to the circuit board. BTW, I realized 2n later that I had posted in the entirely wrong forum was probably too tired when 2n so I reposted in 2n appropriate forum since nobody had answered. Newark and Allied have regional sales offices in many metropolitan areas.
Some of the capacitor types specified below are ceramic.
The catalogs from as many such companies as possible should be obtained before acquiring parts for the amplifier. This has been discussed at n 2n the forum. The ceramic dielectric in the capacitors can exhibit a piezoelectric effect which causes the spacing between the plates to vary with applied voltage.
It 2n be hard not to find recent Japanese transistors that are not better. If you are not familiar with how wire sizes are specified and what wire gauges mean, you can find that information here.
Fred, I assume the double negation was unintentional. This causes the capacitance to vary with voltage.
