Determining Tech-Ohm Ceramic Resistor Current/Power Rating

[fuzzoli]

I picked up a few Tech-Ohm ceramic resistors at an estate sale this past weekend.  The resistance value is printed, but no current/power ratings.  I looked for charts based on size, etc., but no luck.  These particular ones are about an inch in diameter and about 10" long.  Thoughts?

Thanks!

Size is consistent with the very common 225W rated ceramic power resistors. Google Ohmite 270 series for a generic equivalent.

Ah, silly me!  Why didn't I think to look at the current manufacturers!  I was so caught up on the tech-ohm!  Thanks for the quick answer!

You can also load it up while monitoring the temperature, when you reach a power level where it settles at around 125C that's probably a reasonable place to stop.
