Telecommunication measuring equipment Cable and pipe tracing Cooper networks IT networks Optical networks Spectrum analysers more The last thing I can come up with is Eleflow.

K2CBApr 26, A small current entering the base is amplified to produce a large collector and emitter current.

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. Because the controlled output power can be higher than the controlling input power, a transistor can amplify a signal.

A known 2sc9172 “pull” 2SC I had lying around measures 45, which is close to the data sheet spec of “50 typical, 10 minimum”. G4COEMay 26, Until I get this sorted I will never order from Eleflow again nor would I recommend them to anyone.

The radio makes full power on all bands, and the power control is right on the money from w. They measured the hfe of the 2SCs so they send a matched pair – I see they do the same with 2SCs. The bias pot was pretty much within spec ma before I performed the adjustment. My experience with Eleflow.

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 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.

Anyone that gets the original parts from a vendor is extremely lucky. These two kinds of charge carriers are characteristic of the two kinds of doped semiconductor material. All were within data sheet spec, but the s I received are all coming up low at around 2.

Fluke, Mikroelektronika, Knipex and Logitech. I no longer work on TS’s needing 2SC’s replaced.

They did not work. He explained how difficult is to find genuine transistors these days. Just like Cliff I used Eleflow before and without problems. I still have them and the packet here They were shipped back and I never got a refund, they claimed never received. There are tell tale signs, Writing easily smudged off, lead out thinner than usual, very 2sc11972 metal tabs that look different, the gains on the ones I have is 85 way on the high side I reckon.

But I’ve seen that over the years with dtasheet Mitsubishi devices, such as the and devices. The first batch I had from Eleflow worked just fine but not last lot.
