Thin Film Mil chip resistors feature all sputtered wraparound
termination for excellent adhesion and dimensional
uniformity. They are ideal in applications requiring stringent
performance requirements. Established reliability is assured
through 100 % screening and extensive environmental lot
testing. Wafer is sawed producing exact dimensions and
clean, straight edges.
