[RFI] Bulk order source for Ferrite beads?

[Gary K9GS]

I have done two or three bulk purchases of 150+ for my club and always through Arrow.
Always try to order in multiples of 10 as a layer in a box of 100 holds 10.  Minimizes damaged cores in shipping.

I also recommend Arrow, both for cost and service, especially for small 
quantity. It helps a lot that shipping is free for an order of $20 or 
more -- IF it's a web order for what's in stock.  I also got a very good 
price on 100 pieces of the 2.4-in o.d. #31 toroids.  Other good vendors 
are Lodestone Pacific, Dexter Magnetics, and the usual industrial 
electronics houses like Newark, Allied, Mouser, etc.

Note also that there is currently a tariff on these parts, which are 
made in Fair-Rite's factory in China.

BUT -- #61 cores are NOT of much use for RFI suppression below UHF, and 
they are a terrible choice for a common mode choke (often called a 
"current balun").
