[Elecraft] K2: Size of RFC15 - No different from green ones

[Don Wilhelm]

Nick,

Ignore the body color on the chokes - while the body color may have been 
a valid identifying characteristic at the time that phrase was put into 
the manual, it is not a good indicator in the long term - the body color 
can change at the whim of the component manufacturer and may change if 
the component vendor is changed.  There is an effort in place at 
Elecraft to eliminate references to component body color as an 
identifying parameter, but unfortunately, that will appear in future 
revisions of the manuals.

The only identifying characteristic that can be trusted is the color 
coding bands - for 100 uH, the color bands are brown, black, brown. 
Select the smallest (physical size) one for use at RFC15 and use the 
larger bodied ones for use at other locations - if there is no 
difference in size, then either one will do for RFC15.

For RFC15, you will have to form the leads to fit between the solder 
pads - it is OK to form the leads back alongside the choke body.  Do not 
bend the leads sharply up against the choke body with a tool - form them 
with your fingers.  If too much pressure is put on the leads, the wire 
inside the choke can separate from the leads and lead to a damaged 
component.

BTW - Green, brown, Green would be 5,100,000 uH (a very large choke) - 
you must have the body color confused with the color code bands on the 
choke.

73,
Don W3FPR
