SSPA Power Supply - Feedthrough Capacitor

I discovered today that Corcom (now TE Connectivity I guess) made/makes DC Feedthrough Capacitors.  Below are some specifications on the one I'm interested in.

The one I was initially interested in is the 200DFC6-R but I found a batch of 200DFC6-P's for sale at > 50% off new prices on Ebay.  New these run about $165.  The ones I found on Ebay are listed as "New Unused" and cost $75+$6 shipping.  Still a bit pricey if you ask me.  But I think worth a try since between 10-100 MHz Insertion loss is between 50-90db!  90db at 100 MHz.

The "P" model is 1000nF, the "R" that I wanted is 4700nF the "R" model is 70-90db between 10-100 MHz.  

It's good to know these are available at least.

I've ordered the 200DFC6-P from Ebay.

These things are small tho so may be interesting figuring out where to place things around it.  Nearly 6" long and 1.5-2" wide.

Top row is in inches, bottom in mm.

Here's part of the datasheet on them.  Click the image for a large copy or go here to download the whole thing.
