HIGH PRECISION THIN FILM
LOWER PLACEMENT COSTS
RANGE OF STABILITIES
LOW COST IN VOLUME
WIDE VALUE RANGE
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 con vex terminals. A wide value
range and alternative T.C.R's make this a most versatile
resistor solution.
