电阻判别（Resistance discrimination） SMD resistor SMT Sheet resistance is a form of metallic glass uranium resistance. His resistor is a high reliable ruthenium series glass uranium material, which is sintered at high temperature and is made of silver palladium alloy paste. Small size, high accuracy, good stability, because it is a piece of pieces, so high frequency performance. resistance Definition: the conductors resistance to electric current is called the resistance of a conductor. Resistance (Resistor) is the most widely used component in all electronic circuits. The main physical characteristic of resistance is that the electric energy is heat, and it is also a component of energy dissipation. Resistors usually play the role of voltage divider in the circuit, and the AC and DC signals can pass through the resistor to the signal. The resistance has a definite resistance, which represents the magnitude of the resistance current to the flow barrier. The unit of resistance is Ohm and is expressed by the sign Omega. Ohm is defined as when a 1 volt voltage is applied at both ends of a resistor, and if there is a current of 1 amperes in this resistor, the resistor has a resistance value of 1 ohms. Out of the ohm, the units of resistance are also thousands of ou (K, M). The electrical performance indexes of resistors are usually nominal resistance, error and rated power, etc.. It together with other components to form some functional circuits, such as RC circuit. A resistor is a linear component. It is a linear component, because it is experimentally found that under certain conditions the current flowing through a resistor is proportional to the voltage across the resistor - that is, it conforms to Ohms Law: I=U/R Common carbon film resistors or metal film resistors can be simulated by linear resistors when the temperature is constant and the voltage and current values are limited to the rated conditions. If the voltage or current value exceeds the specified value, the r
