ISG Fluid Level Sensor

By Type of Whisker

This makes the electro-mechanical connection between the die and the outside world. There are 2 of them:

  1. M46-0008-00 : This is the original whisker.  It has a cross-sectional area of 0.064 uin2.  The smaller cross-sectional area doesn’t leak as much heat away from the die, so it does not perform as well in hot oils.

  2. M50-1028-00 : This whisker was added in 2010 and has a cross-sectional area of 0.080 uin2.  The larger cross-sectional area leaks more heat away from the die allowing it to run cooler in hot oil applications, raising the turn on voltage and thus achieve a higher withstanding voltage.
