NU33 different one 

Hi All,

I have a NU33. It looks different as I see in this page.

It's a half wave  rectifier. Vf=2V If=1,25mA. Its box says beside the NU33 CV1120

Should I upload its pictures here?

Hello Ottó,

as its construction actually looks same as the CV1120, I've created a NU33 variant called NU33*CV1120.

As soon as this variant appears, you can upload your pictures there.

Best Regards,
Jacob
