Hi everyone:

do you know what kind of component in the attachment, it is placed between LM78L05(IN) and DF01S(+), so I just think it should be diode, but I never saw such kind diode with two color band, the size is =2.5, L=5mm. if you know the type, please tell me ,thank you very much.

 

It looks like an inductor.

 

Hello,

The part you show can be a diode.
The package is called minimelf (an SMD variant).
Do you have the schematic?

PS use PNG or GIF for the attachments, DOC takes time for loading the wordprocessor.

 

Hi:

Thank you your reply, here is the SCH, and D2 is the component I want to know, could you give me some idea, thank you.

 

Hello,
