TX CALIFORNIA MICRO DEVICES Back-Contact Thin Film Resistor Series California Micro Devices TX Series back contact 20 mil resistor chips offer the superior properties of Tantalum Nitride material in a single-bond design. Conductive epoxy or eutectic die-attachment to an active substrate area eliminates the need for a second wire bond. TX Series chips are available in resistance values up to one meg ohm and in tolerances to one percent.
