Digitally Programmable Capacitors

Digitally programmable capacitors allow users to customize the release of stored charges to meet specific requirements for given electrical processes. For example, OCXO oscillators and capacitive sensors perform many functions. Programming a crystal or sensor’s capacitor to deliver a range of charges optimizes each function. Digitally programmable capacitors available from Littelfuse feature memory chips and wired, computer-controlled interfaces. This makes setting the capacitor simple and repeatable. Further improving their usefulness, the programmable capacitors can be used in series and incorporated into shunts.
