The LRK Series of ultra-low resistance thick film resistors is for current-sensing circuits in portable electronic devices such as laptop computers. The surface-mount resistors are part of the family of "flip chip" devices, which are terminated on one side only for face-down mounting on the pc-board. Ultra-low resistance values required for precision current-sensing circuits are achieved through a four-terminal design. The resistors are constructed with a thick-film resistive element on a ceramic substrate with four terminations.

Most machine design engineers will survey existing component manufacturers for standard linear guide products, limiting what they can do with their designs. Using extruded aluminum profile guides can customize machine designs while shrinking the bill of materials.
Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
