Confused with resistor label

maurycy · 27th April 2012, 07:58 PM

This is probably very simple for you experienced DIYers but I am a bit confused. I have a Noble 5W resistor with the following label: RGB5 0.33OhmK. Is this 0.33K Ohm resistor or 0.33 Ohm? I am confused by the K at the end. Service manual calls for 0.33 Ohm.

Here is the picture:

Thanks.

Why not measure the resistors?

Just ignore the K on the end as it will probably be some kind of manufacturer code or will indicate something else related to the resistor. They look like emitter resistors anyway, and normally have a value under 1 ohm, so the 0.33 ohm option is almost certain.

K=10% I think with j=5% on the body of a resistor
so this is 0.33 ohm 10%
