Semicoa 2N2904 Datasheet

Bluewhiteredor green color Great for shining in from the meter edges from the side or 2n29044 behind on the base station meters.

The typical saturated base voltage of the 2N is shown on a graph at 0. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Dec Mon 31, 8: Here’s part of dataheet older datasheet: Doesn’t the 2N has more saturation drop than 2N? One strip will do both meters in a base and light them up bright. I would use a 2N that works well up to mA.

Amber color Great for shining in from the meter edges from the side or from behind on the base station meters.

Many characteristics of transistors depend on the manufacturing processes used, and those are subject to continuous change. Page 1 of 1. I’ve never really understood why dagasheet 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. This Large Clamp-on ferrite choke is a passive component used to suppress HF energy datashert a choke.

Cleaners datassheet other chemical sprays. They certainly can cover a lot of needs for replacements and projects. Spring Clip for knob ring Galaxy Type Knobs. Industry specs for transistor numbers are pretty generic, often in terms of minimums that must be met, or in ranges of numbers. Free air implies that the device is not placed within an enclosure that inhibits air flow and that near by components are not inducing additional heat to the device.

Originally, it was designed as a “high speed switch”. The line indicating thermal runaway runs out another 10 degrees before dropping, for the ‘A’ version parts, and terminates at degrees centigrade. Forums New posts Search forums. The 2N or BC will be a datasheett better.

S-meter plastic bracket goes around the meter in many, many older radios with S-meters. Hope it will perform better than ULN B Vs B Transistors. Jun Mon 27, 1: First Prev 2 of 2 Go to page. The 2N has about 5mA of base current which should be a little more to get a little more 2n290 current with the same saturation voltage loss.

Suraj Active Member Sep 9, Each of the other graph lines are identical between the ‘A’ version and non-A version, so in order to save space the graph showing the other versions of the part are omitted. Data Sheet Commonly used in many older linear amplifiers as keying transistors and RF pre-amp.

The graph only applies to a TO metal package, dahasheet a 2N is also available in a plastic TO package.

Jun Sun 26, 2: This is why manufacturers like Tektronix, HP, Heathkit, and many others used different house numbers to designate common transistors like these. For proper circuit operation use one of the gray curves to insure the 2N does not operate at or near its maximum junction temperature.

Perfect for PL’s and Brass Powers. As semiconductor fabrication improved, what counted as a high speed switch changed, and a lot of that functionality went into a multi-transistor IC. You will not be disappointed with this product, they are very cool and I use them everywhere now.

Seriesdatsaheet,andalso used in some others like the Sweet They were quite the marvel in their day.

TO sounds much better than “Unibloc” – datasheey sounds like a prison section to me. Galaxy, Cobra, Uniden, Ranger, Connex and many many more Pioneer Elite vsxtx water damage no power Started by Watin 3 2b2904 ago Replies: This is the largest clip used for the channel selector knobs. Jun Sun 26, This is the smallest clip in the dual control. Media New media New comments Search media.

A 2N works datassheet above 50mA. Pretty nifty that they are still being made and designed into new products. If you’re covering old transistors, then the hobby favorite, for years was the 2N Welcome to our site!
