Excellent stuff, thanks Brian!

Is that the specs or do you have a LCR meter on hand? I'm asking because I think I need one.....

Aww nuts... Is that the HC101 that I was thinking of getting for my TMM waveguide? I need a 4mH (0.21 ohm) for that one :(

Can I just take off some of the windings to get down to 4mH ? And also the resistance... can I just parallel a 0.31 ohm with it to get it down to 0.21 ?


Apologies if this is gobbeldy gook but I'm flying blind here on 20 year old high school electrical knowledge   :point:

Unwind and you'll get a corresponding reduction in inductance and resistance.

Don't put the resistor in parallel! I will just let all frequencies through. You will get down to about 0.4Ohm DCR, no big shakes. Its double 0.2 but its only 0.2 over, if you follow my drift. ;)

Cool thanks guys... How to measure? Googling tells me I should get an LCR meter but they are all over a grand  :sweat:

Not gonna spend that amount for a once off measurement.

Is that the specs or do you have a LCR meter
measured with LCR meter ...........
( If you are thinking of buying a "tool" later may I recommend DATS  -  u can measure all component values, also  get a nice impedance plot with phase and export same  for simulation , and do T/S on drivers )

Thanks Brian. Parts-express have the DATS for even less. I think I should try and get one of those rather than a LCR then. Thanks!

Also bought one on Brian's recommendation and I am very happy with it.

I think I should save up for one of these. Looks like it can come in really handy.
