Questions & Answers Ask a Question

Why is there no voltage rating for this contact?

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.

Does this product need a pick and place cap for SMT placement?

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.
