To Our Valued Customers:
We appreciate your use of V•I Chip products. Our commitment to customer satisfaction is demonstrated
by our notification to you of a product change.
Description:
As part of ongoing improvements in our manufacturing process, V•I Chip testing has determined an
improved method for calculating Rout that provides better accuracy. Additionally, we have seen some
variation between our multiple PCB vendors in resistance of the PCB. With this new calculation method
and variation in PCB resistance, we are changing the specified value for Rout on the
VTM48EH015T050A00(VIV0102THJ) product. The table below highlights the change in Rout.
