Electronic devices have increasingly high performance requirements for components. In this context, the GMR series of ROHM high-power, low-resistance resistors have become the choice of electronic engineers for their excellent performance and wide range of applications.
The GMR series ROHM resistors range in size from 5025mm to 7142mm, which can be adapted to the needs of different Spaces and installation environments. Whether they are found on compact circuit boards or in large power equipment, the series of resistors can be rated from 4W to 10W, and can meet a variety of application scenarios from low power to high power.
The selection takes into account the operating conditions of the circuit, including the operating voltage, current and expected ambient temperature, etc. According to these conditions, the required resistance power and resistance range can be determined. The GMR series resistor provides a resistance value selection from 5mΩ to 220mΩ, which can meet the needs of most circuits.
In addition to the above, it is also necessary to consider the accuracy and stability of the resistance, for the circuit that needs to accurately control the current, the resistance with higher accuracy should be selected; For occasions where the working environment temperature changes greatly, a resistance with lower TCR should be selected to ensure stability. The GMR series resistors are made of special alloy materials with low TCR characteristics and can maintain stable resistance values at different temperatures.
In terms of application, GMR series resistors are widely used in various electronic devices. For example, in communication equipment, it is used to control the strength and stability of signal transmission; In power equipment, it is used to divide voltage and limit current to protect other components; In industrial control systems, it is used to adjust the speed and torque of the motor; In consumer electronic products, it is used to achieve the normal operation of various functional circuits.
