01-99999999M 01% 025W 25PPM Programmable Resistor Board Resistance Tolerance 01% High Precision 8-Segment _x000D_ 0.1-9.9999999M 0.1% 0.25W 25PPM Programmable Resistor Board Resistance Tolerance 0.1% High Precision 8-Segment _x000D_ _x000D_ 1. The resistor board uses 0.1% precision resistors, not 1% ordinary resistors. _x000D_ 2. The resistor is plug-in, not patch. The distance between the two pins of the patch is small, moisture makes the resistance value smaller, and the stability _x000D_ is poor. _x000D_ 3. Instead of using a DIP switch, a gold-plated pin is used. The contact resistance of the DIP switch is too large, which affects the accuracy of the small resistance value. The contact resistance of the gold-plated pin is more than half smaller than that of the DIP switch. _x000D_ _x000D_ Name:8 Segment decimal programmable resistor board (one thousandth) _x000D_ Resistance range:0.1-9.9999999M _x000D_ Resistance power:0.25W _x000D_ Note:There are differences in the factory batch number silk screen, which does not affect the use. _x000D_ Colour:Purple _x000D_ Material:PCB+electronic components _x000D_ _x000D_ Package Contents: _x000D_ 1 * Resistance box _x000D_ _x000D_ Only the above package content, other products are not included. _x000D_ Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
