ELLON-ESR bare copper shunt resistors are mainly characterized by low resistance, high power, and low temperature drift, and are widely used in current sampling circuits. In current sampling circuits, the stability requirements for resistors are extremely strict. Therefore, different product materials have different product characteristics and application markets. With the market demand for product miniaturization, low power consumption, and fast charging and discharging, ELLON has launched a small volume high-power bare copper shunt resistor. This article provides a detailed introduction to the corresponding specification parameters.
The high-power bare copper shunt resistors added by ELLON this time are mainly concentrated in the low resistance parts of 1206 (3.2 * 1.6mm) and 2512 (6.4 * 3.2mm), providing power and greatly saving product space and production costs. Below is a table listing the parameters for the newly added resistors of the ELLON brand:
