Voltage rating is calculated from the flashover voltage – the voltage at which the electricity can break down the air gap and jump between two contacts. With a single contact, the voltage rating you achieve will depend on the space you leave between two contacts, or a contact and any other conducting element. So we are unable to give a voltage rating for single contacts, as it will depend on your usage.

Voltage rating is based on the maximum voltage, with a safety margin (can be calculated at 33% to 66% of the maximum voltage). However, to find the maximum voltage, it has to be tested for the voltage level at which flashover occurs – and this depends on the gap to the next nearest contact or other metal object (like the enclosure). As this contact pad is a single contact, and not a row of contacts, we have no control over the distance to the next nearest metal object – this will depend on your design. You will therefore need to evaluate and test for this within your specific layout, sorry.

These designs were intended for SMT soldering to a PCB or similar, rather than wire mounting. You could either make a wired connection elsewhere to the PCB, or investigate methods for soldering wires to flat surfaces.

A separate pick and place cap is not necessary (and is not supplied) – the part has an integrated flat surface that should be used for pick and place purposes. You just need to specify a vacuum nozzle of the right size.
