smd identification

04/19/2011 4:28 PM

This isnt particularly important. Just curious. I am trying to identify an smd componant and havent benn able to confidently do so. Im pretty sure its a resistor. The markings are .... 226 10k 552. Thank you.

They look like tantalum (polarized) caps to me. The red marking on one end shows the polarity. The 10k could be the value in nanofarads which would be 10mfd, a pretty common value for these. I'm not sure how to interpret the other numbers.

I'm taking an educated punt on this one.

Definitely a capacitor most likely Tantalum, the Band at one end denoting polarity(+).

Value is either 22uF 10Volt or could be 10uF (nominally 10V). Sounding it out on an LCR meter as a capacitor will give you the right value but not the voltage.

I'm suggesting that 226 is the value and 10 is the voltage. Not sure what the 552 is could just be the manufacturers mark or it may be a further code for tolerance.

If you turn them upside down is there a makers "stamp" underneath? That would help in identifying them further, at least by googling the manufacturer you could "perhaps' get a handle on their code.
