INTRODUCTION
The SMRxD is a precision molded surface mountable
resistor offering all the elements of precision; including low
TCR, tight tolerance, long term stability, low noise, low
thermal EMF, and non-measurable voltage coefficient. It
utilizes the Bulk Metal
®
Foil technology for the resistive
element with its inherent low and predictable TCR and long
term stability. This surface mountable product affords similar
performance to the time tested S series molded through-hole
product.
The flexible terminations of this product also reduce
stress transference from the PCB to the resistor.
Voltage division with tight tracking < 3 ppm/°C can be
achieved with 2
randomly
selected units even with a large
ratio between the two values.
Our Application Engineering Department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please

If I set some I/O ports to input ports and then set them to a high level, will there be any impact?
For example, for port A of 16F73, setting TRISA=0XF0 means that the upper 4 bits are input and the lower 4 bits are output. If PROTA=0xFF is executed, will it affect the input of the upper 4 bits?...
