Constantan shunt resistors are used for precise current measurement and are available in various resistance values, including 10 milliohm (mR) and 20 milliohm (mR). Here are some details about these resistors:

10mR and 20mR Constantan Shunt Resistors

1. 10mR Constantan Shunt Resistor:
   - Commonly used for applications requiring low resistance values.
   - Features include stable performance, low inductance, and high reliability.
   - Dimensions for a typical 10mR resistor can be around 1.2 x 10 x 18.5 mm.

2. 20mR Constantan Shunt Resistor:
   - Similar applications as the 10mR resistor but with a slightly higher resistance.
   - Available in various package sizes, often sold in lots 
   - The 20mR resistors are also characterized by their low inductance and stable performance, making them suitable for accurate current sensing in electronic circuits.

Both types of resistors are ideal for use in applications such as power monitoring, battery management systems, and other electronic devices where precise current measurement is critical.
