0.1Ω-9.9999999MΩ 0.1% 0.25W 25PPM Programmable Resistor Board Resistance Box w/ 3D-Printed Enclosure

Attention:
The resistor board comes with a 3D-printed enclosure. Due to occasional material variations from the supplier, the enclosure color may be either dark gray or light gray at random. The actual color may differ from the gray shown in the pictures. Please make sure that you don't mind before purchasing. Thank you!

Description:
This resistor board uses a large number of 0.1% precision resistors with copper leads and a low temperature coefficient of 25PPM. In contrast, many competing products use 1% tolerance resistors, which are not in the same class. The raw material cost for this board is significantly higher.

Advantages:
* The resistor board uses 0.1% precision resistors, not standard 1% resistors. The material cost difference between the two is dozens of times.
* The resistors are through-hole components, not SMD (surface-mount) types. SMD resistors have smaller pin spacing and are more susceptible to moisture, which can reduce resistance and lead to poor stability.
* We do not use DIP switches. Instead, we use gold-plated pin headers, as DIP switches have large contact resistance that negatively affects the accuracy of low-resistance measurements. Gold-plated pins have less than half the contact resistance of DIP switches.
