I remember when all Hams had to pass an examination that included how to
read the color codes on resistors and capacitors. Sigh! But that was back in the good ol' days ... sigh ...

Inside it has a 0.6 ohm 40 watt resistor inline with input and ouput. Off each end of this resistor it has a silver button mica capacitor. My "cheatsheet" for silver button micas is not to be found. I wonder if someone can tell me the capacitance of a silver button mica that has the following six colors: black, brown, red, green, gold, grey. tnx & 73 hank wd5jfr Hi Hank, Practical issues like this are often deferred while angel population counts on pin-heads are being conducted. ;-) There are two styles of marking these components. One occupies half the arc of the button, the other occupies 240 degrees of the arc. Given that you start with the color black, I would presume this is of the first variety. As such: 1,2, X100000, 5%, 6 GOhms resistance. 73's Richard Clark, KB7QHC |

Ever see a color code on an SMD device? :-) -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
