precision thin film resistors

INTRODUCTION

High precision, thin film resistors manufactured with a NiCr alloy spattered onto an alumina substrate. TP resistors
have linear operating temperatures from -55C to +125C.  Standard TCRs include 2ppm/C and 5ppm/C.  These models
also exhibit excellent long-term stability, low current noise, a low voltage coefficient and a low thermal EMF. Typical
applications are:  Discrete voltage dividers, analogue circuits in industrial measuring equipment, control, medical
electronics, ATE, aerospace, and reliable power electronics.
