Default Re: Possible faulty AF127?

Hi Terry

Firstly it's nice to see I'm not alone up here in North Devon!

I recently had a batch of 10 AF127's in so thought I would test some and let you know the results

No. B-E. B-C. HFE (measured on peak component tester)
1. 0.31. 0.24. 193
2. 0.30. 0.26. 378
3. 0.29. 0.22. 208
4. 0.31. 0.22. 462
5. 0.30. 0.22. 97

Hope that helps. Interesting that the diode readings remained pretty much the same despite the different hfe.

Regards

Graham
