Resistance value must be checked using 4½ digit micro-ohm meter with four wire system
and insulated clips and the designer of the pad layout might prefer to split the pad for four wire checking.

TYPICAL APPLICATIONS
These devices have been introduced to answer the increased demand for power resistors which can be surface mounted.
The HSVAS Series caters to those who require a normal wire wound with surface mounting and the HSVALS series
caters to those who require a shunt / current sense device which is surface mounted.
Note :
Due to recent technological advances, the ceramic cases used may be steatite ceramic or corderite ceramic or high alumina
ceramic depending on the nature of the application. Hence the ceramic cases may be off-white or variations of brown and
variations of grey; colours which are inherent to these ceramic materials.
