The last thing I can come up with is Eleflow. Sure would be interesting to hear their response. I even increased the bias setting to see if there was any change.

The bias pot was pretty much within spec ma before I performed the adjustment. A known good “pull” 2SC I had lying around measures 45, which is close to the data sheet spec of “50 typical, 10 minimum”.

They appear to look like genuine Mitsubishi devices, although the labeling differs ever so slightly. Fortunately my payments were quickly and fully refunded in both cases. Bias set datashee according to specs with no issues. Comfort Flexible options, including door to door transportation. All were within data sheet spec, but the s I received are all coming up low at around 2.

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. All 6 I received measure an HFE of 2.

G4COEApr 27, Region Macedonia Kosovo Global. Datassheet am guessing that he may not even be aware himself that this time around there is an issues with his supplier.

Leads much thinner than original. Education equipment Industrial test tools Catalogues Laboratory 2sd1972 equipment Measuring of environmental and ambient parameters Equipment for testing of medical equipment Calibration equipment Soldering equipment Telecommunication measuring equipment.

But I’ve seen that over the years with other Mitsubishi devices, such as the and devices. The radio makes full power on all bands, and the power control is right on the money datasjeet w.

And their buyer protection seems to be too good not to give them a try. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Equipment for testing of medical equipment. The customer is in the focus We want to make sure that customer is the center of attention. K2CBApr 26, Cables, Accessories Cables Accessories.

I purchased 2SCs from this same broker a few years back with good results, so I did not hesitate to try him again. Next, I decided to perform an HFE gain test on the devices received. 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.

I am pretty sure a have a spare pair. Until I get this sorted I will never order from Eleflow again nor would I recommend them to anyone.

2SC MITSU ORIGINAL

NPN is one of the two types of bipolar transistors, consisting of a layer of P-doped semiconductor the “base” between two N-doped layers. Something I never thought about is alternatives They list the transistor as being in their current production list. Collector – Emitter Voltage Vceo.

Calibration equipment Electrical calibration equipment Pressure calibration equipment Temperature calibration equipment. Collector – Base Voltage Vcbo. 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 Well, I ordered from two separate AliExpres vendors.

I no longer work on TS’s needing 2SC’s replaced.
