[OFARC] parts for 20m band pass filter

[Ralph (home)]

a note regarding capacitors for other bands ....

the capacitors I used for the 20M filter are all low loss .. especially the 150 pF
each manufacturer has several families (series) of capacitors
Each family has a range of capacitor values to choose from, so you can use the same part number and search for the value you need.

for example, the 150 pF capacitor is part of the 598 series
if you need 220 pF, use the same part number except replace the 15 with 22 so 98-CDV16FF151JO3F  becomes 98-CDV16FF221JO3F 


for 40M I suggest the following:
      Value needed Voltage rating quantity available value Quantity mouser part no. Price each 
      112 pF 3kV 1 56 2 75-564R3DF0Q56  $      1.13  
      136 pF 3kV 1 68 2 75-564RC0GAA302EL680   $      2.97  
      164 pF 1kV 1 82 2 810-CC45SL3FD820JYNN  $      0.44  
      630 pF 1kV 1 330+270+33       
          330 1 598-CDV16FF331JO3F    $      1.93  
          270 1 598-CDV16FF271JO3F    $      1.68  
            33 1 75-564RC0GAA302EK330   $      2.14  


let me know if you want me to suggest parts for other bands
