Hi TN,

Is there such a thing as an embedded resistor material  that's suitable for higher frequencies? Application does not warrant
great precision (~5% to 10%), it's just for dealing with signal attenuation at stubs.

Could be part of a Cu foil, or deposited and cured/baked. Might be inner or outer layer. Have considered carbon contact type
materials but do not have much faith in long term reliability (for class 3 Telcom).

All of the embedded materials that I've come across are nickel based, which is not going to be a realistic proposition due to
the ferromagnetic properties.

Best Regards

David Greig
