MEGGITT HOLSWORTHY HYBRID CIRCUITS ELECTRONIC ASSEMBLIES PRECISION RESISTORS SMD PRECISION RESISTORS PRECISION NETWORKS SMD Precision Thin Film Network TYPE MRS SERIES The MRS series is an entirely new chip network utilising nickel chrome sputtering on high purity alumina. This network has been designed for high volume applications and is offered with 4 isolated resistors on a single substrate (12.06 sizes) at 0.1% with convex terminals. A wide value range and alternative T.C.R's make this a most versatile resistor solution.
