Something I never thought about is alternatives He explained how difficult is to find genuine transistors these days.

The customer is in the focus We want to make sure that customer is the center of attention. The first batch I had from Eleflow worked just fine but not last lot. I no longer work on TS’s needing 2SC’s replaced. They measured the hfe of the 2SCs so they send a matched pair – I see they do the same with 2SCs. G4COEMay 26, Any thoughts, comments, or suggestions?

KV6OMay 26, These two kinds of charge carriers are characteristic of the two kinds of doped dataeheet material. The last thing I can come up with is Eleflow. The bias pot was pretty much within spec ma before I performed the adjustment.

Anyway, I installed a pair into the TS I even increased the bias setting to see if there was any change. Comfort Flexible options, including door to door transportation. I can’t get replacements that I can rely on. The ones I have would not even fit in a TS their body being slightly bigger.

The radio makes datasheet power on all bands, and the power control is right on the money from w. Soldering equipment Soldering irons Soldering stations HotAir stations Desoldering stations Multifunction stations more 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. Anyone ratasheet gets the original parts from a vendor is extremely lucky. Collector – Emitter Voltage Vceo.

They may have unusually high hfe. All were within data sheet spec, but the s I received are all coming up low at around 2. K2CBApr 26, Until I get this sorted I will never order from Eleflow again nor would I recommend them to anyone. Telecommunication adtasheet equipment Cable and pipe tracing Cooper networks IT networks Optical networks Spectrum analysers more Free technical support If something goes wrong, we will be ready and willing to help!

I’ve got some ‘duff’ ones from Eleflow just like Cliff did for a TS – mine won’t fit!!!!! They list the transistor as being in their current production list.

Region Macedonia Kosovo Global. Thanks for all the suggestions. All 6 I received measure an HFE of 2. A known good “pull” 2SC I had lying around measures 45, which is close to the data sheet spec of “50 typical, 10 minimum”.

2SC MITSUBISHI, 2SC Datasheet

I had a long chat with him on the phone before buying them. Same for a few other RF devices I measured. Comments 0 Write your comment. Cables, Datxsheet Cables Accessories.

Equipment for testing of medical equipment. It is composed of semiconductor material with at least three terminals for connection to an external circuit. Sure would be interesting to hear their response.
