PTC silicon die precision thermistors

PTC silicon die precision thermistors are used in wire-bonding and specialized reflow-soldering applications. Board attachment by either wire bonding, conductive epoxy, or a combination of both may be used. Solder attachment may be performed using different solder configurations, however it is not recommended.
