NEW Old Stock
Even though this new, it is old stock and being just one, I have made basic tests
Confirming that it tests fine and the hFE measures 140
Clean legs with only slight signs of oxidisation, still perfectly solderable
To maintain this condition I have now placed the device into a sealed clear plastic packet
NEW
Exactly as described
