I thought I was pretty good at reading schematics. C= capacitance R= resistance, etc. I am working on a Flex 5000A Antenna Tuner (schematic attached). It lists L12 as 'W950'. L usually means inductor. In this case, I think it means some sort of Ferrite. Several of the regular inductors are listed in uH (as expected). There is no Parts List associated with this schematic - so, I'm not sure what a W950 is. Seems there are two types on the schematic; W950 and W650 It's a surface mount - guessing 1206 size Any thoughts on this?
