Network resistors

[etack]

I'm looking for any Info on SIP network resistors.

Anyone have any knowledge of PMs that are in them. I know the are RuO thick film they are also through hole styles too.

Bourns, CTS and Dale made 90% of them. A Google search on "resistor networks" will uncover a lot of datsheets. Also look for full-line catalogs, as they generally go into the composition of products more than data sheets. Resistor networks (ladder, bussed, and discrete) have been around since the dawn of the digital age, so data from the 60's could be relevant.

Most are just thin metal film, and 90% hermetics - the epoxy, leads and sealants. Very little there when you remove all that. The DoD precious metal recovery program has them as null- not a part of the program, unlike boards, connectors, chips, and pins.

Cheers,
