It sounds just like when the bias is improperly set too low on an amplifier, yet I triple checked to make sure it is set correctly in this case. Collector – Datasheef Voltage Vceo. Well, I ordered from two separate AliExpres vendors. They list the transistor as being in their current production list. A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power.
Free technical support If something goes wrong, we will be ready and willing to help! Tabs look different and very shiny. Until I get this sorted I will never order from Eleflow again nor would I recommend them to anyone. Well, two separate suppliers from AliExpress, and both were counterfeit.
Anyone that datasheer the original parts from a vendor is extremely lucky. That is just gotta be a logical answer Roger. So even though they look authentic in almost all aspects, I am now suspecting that they also may be knockoffs, albeit much better done than the Chinese AliExpress junk K2CBApr 26, Because the controlled output power can be higher than the controlling input power, a transistor can amplify a signal. They were shipped back and I never got a refund, they claimed never received.
Your name or email address: These two kinds of charge carriers are characteristic of the two kinds of doped semiconductor material. KV6OMay 26, You must log in or sign up to reply here.
I still have them and the packet here There are tell tale signs, Writing easily smudged off, lead out thinner than usual, very shiny metal tabs that look different, the gains on the ones I have is 85 way on the high side I reckon.
They appear to look like genuine Mitsubishi devices, although the labeling differs ever so slightly. Comfort Flexible options, including door to door transportation.
Fortunately my payments were quickly and fully refunded in both cases. Next, I decided to perform an HFE gain test on the devices received. G4COEApr 27, I contacted Eleflow, I sent them pictures as requested and still waiting to hear from them ages ago, I Emailed several times!
Region Macedonia Kosovo Global.
Sure would be interesting to hear their response. In contrast, unipolar transistors such as the field-effect transistors have only one kind of charge carrier. I am pretty sure a have a spare pair. Computer components Hardware Network Notebook-Battery.

The radio makes full power on all bands, and the power control is right on the money from w. G4COEMay 26, A known good “pull” 2SC I had lying around measures 45, which is close to the data sheet spec of “50 typical, 10 minimum”. Sadly, it’s not just the TS they are used in, there are many other rigs as well, I am certain if you come across any NEW ones they will be fake or copies call them what you will I had a long chat with him on the phone before buying them.
They measured the hfe of the 2SCs so they send a matched pair – I see they do the same with 2SCs. I’ve got some ‘duff’ ones from Eleflow just like Cliff did for a TS – mine won’t fit!!!!! Something I never thought about is alternatives A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals.
The last thing I can come up with is Eleflow.
I even increased the bias setting to see if there was any change. Education equipment Industrial test tools Catalogues Laboratory measuring equipment Measuring of environmental and datasheeg parameters Equipment for testing of medical equipment Calibration equipment Soldering equipment Telecommunication measuring equipment. Especially when the power control or mic gain is run low.
They did not work. As I said my Eleflow devices these ‘have’ the hallmarks of fakes or very poor copies. I am guessing that he may not even be aware himself that this time around there is an issues with his supplier. 2sc19972 thoughts, comments, or suggestions? I can’t get replacements that I can rely on. Just like Cliff I used Eleflow before and without problems. The bias pot was pretty much within spec ma before I performed the adjustment.
