Current Sensing Resistors from Isotek are High Precision


Isotek offers the widest range of current sensing resistors for Surface Mount, Bus Bar Mount, Wire Bondable, PCB Mount, and Heat Sink Mountable applications.

Isotek's surface mount current sensing resistors include two and four-terminal models, welded (bus bar mount), Kelvin, TCE compatible with dbc mounting, four and two terminal (Kelvin) 'flip-chip', Zero Ohm Jumper Size, and many more. The BVR current sensing resistors are designed to overcome the mechanical stress to solder joints caused by the differences in temperature coefficient (tce) of traditional surface mount resistors when soldered to a ceramic or IMS substrate.

With heavy resistor element and excellent heat conductivity, the BVS sensing resistors series offer a unique structure, for a low-ohmic surface mount resistor with rugged terminals that guarantee good solderability.

Designed as 'flip-chip' mounting resistors, the PMA, and PMD series are great current sensing resistors for applications in SMD power modules and hybrid circuits.

The SMK, SMP, SMS, and SMT are all low-ohmic sensing resistors that offer the state-of-the-art in miniaturization. The patented design combines excellent electrical properties with extremely small size, high-power rating, and an effective and reliable mounting technology.

For harsh environment where precision current sensing resistors are needed, Isotek offers the SMR, and SMV series. The molded packages make them ideal for automotive applications.

Since 1989, ISOTEK has been building a solid reputation for quality current sensing resistors and personal service. Backed by more than 25 years of sales experience and an expanded line, Isotek is now able to offer a wider range of solutions with cost-effective precision products.
