These are brand new 270pf 100V Murata Feedthrough Capacitors part number: DSS1NB32A271Q91A and are used only on the latter model Commodore 64's, namely the C64C and some very late Breadbin models with board Assy 250469 or version E.

These sit in the bottom right corner behind the controller ports and the big axial capacitor and fuse and are labelled EM1 through to EM9. They are there to protect the CIA chip from static discharge on the controller ports. I have read online that the original brown versions used by Commodore are unreliable and often fail but I don't know how true that is.

There were two main types that these boards used, Rev. A used what looks like a standard disc capacitor but has 3 leads and Rev. B  uses a disc capacitor with two ferrite beads on the outer two pins and the middle pin being forward one step with the pins arranged in a triangular shape. Thankfully Commodore designed the Rev. B to use both styles of filters.

You will receive 9 of the filters in the pictures.

Buyers outside the UK:

I use eBay's Global Shipping Programme (GSP) for international sales and I have no control over what they charge for postage. How it works is I send the package to their warehouse in England and they relabel the package with the customers full details and it gets sent on to its final destination. I receive my standard UK postage costs and the rest of what you are charged goes to GSP. I don't get to see how much the customer is charged for international shipping, it appears to me as a normal UK sale but marked as "international sale through the Global Shipping Programme"
