For me its base current will be Series,andalso used in some others like the Sweet The rest of those characteristics are buried in the 50, or so different transistor datasheft that have been created over the years. Common repair part for the Cobra GTL. First Prev 2 of 2 Go to page.


A house number might point to a particular supplier, process, or selection for some particular characteristic–or it may just be a generic part. TO sounds much better than “Unibloc” – that sounds like a prison section to me.

A 2N works poorly above 50mA. The graph shown above covers both the 2N and the 2N I’ve never really understood why there needs to be 50, different transistor types or whatever the number isbut it’s nice to see a few types stand the test of time. Hi I need 4mA of average current. This is the largest clip used for the channel selector knobs.

The line indicating thermal runaway runs out another 10 degrees before dropping, for the ‘A’ version parts, and terminates at degrees centigrade. Datasheets, Manuals or Parts. White Blue red Green.

Pretty nifty that they are still being made and designed into new products. Suraj Active Member Sep 11, The Top curve is thermal runaway and cannot be used as a derate design curve since it exceeds the maximum ratings for the 2N Also be aware that this radio is very sensitive around static electricity and should be disconnected from the antenna when lightning storms are near by.

Jun Sun 26, 2: Jun Sun 26, 8: Then the base current is only 4.

B562 Vs B772 Transistors

Doesn’t the 2N has more saturation drop than 2N? Google [Bot] and 4 guests. I got some improvement in LED brightness. Here how I did. Spring Clip for knob tips. Previous topic Next topic. This is the larger clip in the dual control. Both cost the same at Digikey today. Maybe only the first dozen or so are given on a typical spec sheet. Replacement Transformer Started by ncag Today at 7: In the heyday of transistor development there were new materials and processes being developed on a seemingly daily basis, to overcome short comings of previous designs, and those new devices deserved their own new shiny type number.

Thread starter Suraj Start date Aug 16, Page 1 of 1. 2n22904 paid that princely sum in for the little blue wonder. Heads up- Dataxheet Price of many China made items went up in price due satasheet tariffs.


2N Datasheet(PDF) – Seme LAB

The typical saturated base voltage of the 2N is shown on a graph at 0. The curve for the 2NA and 2NA is basically the same except for the dashed lined. Up until a few years ago I still had a couple brand new, in the box CKs in my parts inventory, but sadly I’ve lost track of them. Forums New posts Search forums.

Replacing a 4 pin leaded inductor with a 2 pin 2h2904 by gkmaia Yesterday at To completely characterize a bipolar junction transistor you need more than 40 parameters. Product Description Your Price.

For proper circuit operation use one of the gray curves to insure the 2N does fatasheet operate at or near its maximum junction temperature.

The item most overlooked when ordering a custom radio is the microphone. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Transistor Derating Curves Temperature derating is a standard design practice for electrical engineers. Still dtaasheet lots of them.
