And their buyer protection seems to be too good not to give them a try. These two kinds of charge carriers are characteristic of the two kinds of doped semiconductor material. Calibration equipment Electrical calibration equipment Pressure calibration equipment Temperature calibration equipment.

The first batch worked fine. Because the controlled output power can be higher than the controlling input power, a transistor can amplify a signal. That is just gotta be a logical answer Roger. Lettering easily smudged as if wet. I am pretty sure a have a spare pair.

Free technical support If something goes wrong, we will datahseet ready and willing to help!

2SC 데이터시트(PDF) – Mitsubishi Electric Semiconductor

Tabs look different and very shiny. A gain of 2 sounds pretty bad to me, I would estimate a gain of around 30 might be typical on the best of devices, this could be the answer to the distortion at low power. The ones I have would not even fit in a TS their body being slightly bigger. I still have them and the packet here The first batch I had from Eleflow worked just fine but not last lot.

Comfort Flexible options, including door to door transportation. Sure would be interesting to hear their response. Especially when the power control or mic gain is run low.


The bias pot was pretty much within spec ma before I performed the adjustment. Leads much thinner than original. My experience with Eleflow. Collector – Emitter Voltage Vceo.

He explained how difficult is to find genuine transistors these days. Your name or email address: They may have unusually high hfe. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Bias set up according to specs with no issues. Education equipment Industrial test tools Catalogues Laboratory measuring equipment Measuring of environmental and ambient parameters Equipment for testing of medical equipment Calibration equipment Soldering equipment Telecommunication measuring equipment.

Computer components Hardware Network Notebook-Battery. There are tell tale signs, Writing easily smudged off, lead out thinner than usual, very shiny metal tabs that look different, the gains datashset the ones I have is 85 way on the high side I reckon.

Until I get this sorted I will never order from Eleflow again nor would I recommend them to anyone.


The customer is in the focus We want to make sure that customer is the center of attention. 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.

You must log in or sign up to reply here. A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. Weazle66 is listed on their site as being an authorised distributer on E-Bay.

I no longer work on TS’s needing 2SC’s replaced. K2CBMay 26, G4COEMay 26, The fakes transistors I got from Eleflow if I remember correctly had a gain of about 90 – and I say again they would not fit in the TS, had all the hall marks of fakes.


They measured the hfe of the 2SCs so they send a matched pair datasheeg I see they do the same with 2SCs. Fluke, Mikroelektronika, Knipex and Logitech. In contrast, unipolar transistors such as the field-effect transistors have only one kind of charge carrier.

2SC1972 Source?

They did not work. They appear to look like genuine Mitsubishi devices, although the labeling differs ever so slightly. I purchased 2SCs from this same broker a few years back with good results, so I did 2zc1972 hesitate to try him again.

Just like Cliff I used Eleflow before and without problems. Cables, Accessories Cables Accessories. 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 catasheet will be fake or copies call them what you will Equipment for testing of medical equipment.

I am guessing that he may not even be aware himself that this datashdet around there is an issues with his supplier. Well, I ordered from two separate AliExpres vendors. Collector – Base Voltage Vcbo. It is dattasheet of semiconductor material with at least three terminals for connection to an external circuit. Fortunately my payments were quickly and fully refunded in both cases. I suspect the low HFE may be causing poor linearity or poor slow RF switching, thus resulting in the distorted tx audio.

The radio makes full power on all bands, and the power control is right on the money from w. KV6OMay 26,
