Model SMNZ offers extremely low TCR (absolute and tracking), excellent load life stability, tight tolerance (absolute and matching), excellent ratio stability, low current noise, low voltage coefficient and non sensitivity to ESD - all in the same resistor. The SMNZ Surface Mount Network is made up of 4 independent Bulk Metal(R) Z-Foil resistors in a small standard molded epoxy package with 50 MIL lead pitch (JEDEC MS-012 package). The electrical specification of this integrated construction offers improved performance and better real estate utilization over discrete resistors and matched sets. The resistor may be used independently or as divider pairs. Our Application Engineering Department is available to advise and make recommendations.
