Using the CAB8 and CAB12 without an interposer

Posted on 10 January 202023 March 2020 By Josh

Though our interposers offer a wide variety of connectivity options, you may want to just plug the bulky CAB8 or CAB12 directly into your application. We use high-density D-sub connectors from the AMP-TE AMPLIMITE 0.50 Series, which can be purchased from any of the large online distributors (e.g. Farnell, Digikey, Mouser). Part numbers for right-angle and vertical connectors are listed in the table below.

How much current does each input of my device require?
How much voltage is required to achieve this current?
What is the resistance of my on-chip heaters?
What precision do I need?
Does my device care about the direction of current flow?
How many inputs does my device have that need to be driven?
