HF Low Pass Filter Circuit Board - T50-2 Toroids - SMA  LPF7o

Description

Low Pass Filter Circuit Board - HF
Board is 1.6mm thick and will accept SMA end launch connectors (included) and up to 22ga wire where cores are to be installed.
The SMA connectors can be used while testing/adjusting. Remove these if installing into an enclosure.
These fit nicely inside a 1590A aluminum enclosure (stomp box) and will likely perform better due to the shielding.
(again, will need to remove the SMA connectors if you installed them)
Dimensions are 2.75" (70mm) x 1.25" (32mm)
Included toroids are T50 type 2 from Micrometals.
I have found that 22ga enameled solid wire works great for experimenting with this size setup.
I inadvertently sized the capacitor place holders to a CD10 size silver mica cap which is rather small.
However small MLCC's work fine.
I will size to CD15 in my next batch to allow for the use of larger cap sizes. (similar to other boards I have listed)
Lead spacing for the caps is 3.6mm and diameter of holes is 1.1mm.
This is a shunt first, 7th order design with spots for 2 capacitors in parallel at each point, but only one required.
A great board for experimenting with different inductances and capacitances to achieve the curve you're looking for.
A Mill-Max 0415 (not 415) will work perfectly in the electrical connection (hardwired) openings.
(use 20-23ga wire if using the Mill-Max 0415, otherwise16 to 22 gauge works great)
Feel free to ask questions before ordering.
I had the boards manufactured in China, but item will ship from Clearwater, Florida.
The photo with the blue background is an example 40 meter setup using #22ga enameled wire on T50-6 cores with small MLCC caps.
My soldering job at the connectors isn't the greatest but it shows how easily this can be assembled.
NOTE:
If you should order more than one, eBay will calculate multiple shipping charges incorrectly.
I will refund you the difference between what I actually pay and what you were charged for shipping multiple items.
I can usually ship 2 or 3 of these for the same shipping price as if shipping only 1.
Thanks for looking, 73
