STATE-OF-THE-ART TECHNOLOGY
tomers with tip and ring resistors on the same component for
single placement processing. Customer lead times are reduced
because parts are readily available. Bourns is an experienced
supplier of state-of-the-art thick film overcurrent protection
devices. Bourns also has global design and manufacturing cen-
ters for localized service.
resistors on the same package, fusible links which are “fail safe”
integrated with surge resistors and custom electrical configura-
tions and tolerances. The thick film line protection network also
has quick-turn sample times.
