- Resistors for over-current sensing and battery charge detection
- Resistor Line-up from 0.5mΩ
- Metal Plate type chip resistor and Wide terminal type resistor for high power application
Current sensing resistors are intended to detect cases of overcurrent or remaining battery levels by sensing currents.
Due to today's functional development of electronics, the amount of current used in circuits is increasing, raising the demand for resistors ready for high power. In addition, there is an increasing need for resistors with a lower resistance to reduce power consumption in circuits, and high precision resistors capable of maintaining an excellent temperature coefficient of resistance even in severe temperature environments.
Panasonic offers resistors with a wide range of resistance from 0.45 mΩ to 1 Ω for the purpose of minimizing the effects of heat generation on circuits.
We have various types of current sensing resistors to meet your needs. We are also widening the resistance range and expanding the lineup, including the high-power and low-resistance types
As the performance of battery-powered mobile equipment grows, the energy consumption is increasing, making it necessary to detect the amount of current used in circuits. Current sensing resistors are intended to minimize the power loss and convert a circuit current to a voltage. They are used for a variety of purposes as shown below.
