I was reviewing a schematic I found on-line at Cypress Semiconductor for one of their capsense products.·
While reading through the schematic I saw references to "no load" as the value on a couple capacitors and a couple resistors.·
In the version notes of the schematic there was another note "zero ohm resistors replaced with no load resistors".·
I know what a zero ohm resistor is.·
In the places in the Cypress schematic I think a zero ohm resistor would have done.·
I don't understand what a "no load" capacitor or a "no load" resistor is.·
Can any one educate me?
My best guess, and it is only a guess,·
is that a "no load" cap or resistor is an actual device to be stuffed on the board but is really an open (instead of a short. 0 ohm).·
Does that make sense?·
Even though a device is populated it is still open?·
Why populate the device then and instead just leave the footprint empty?·
Perhaps to keep someone from accidentally stuffing it and causing a short?·
That would make sense for the capacitors but I am not so sure about the resistor, but that probably depends on the application.
Thank you for any insights or defintions you can provide.
