EVER OHMS
alloy resistor is a commonly used electronic component, and Tian'er is one of many well-known international brands. Its resistor has high accuracy, stability, and temperature coefficient, and is widely used in various circuits. This article will introduce the working principle, characteristics, and correct usage methods of
EVER OHMS Alloy Resistance. The working principle of Tian'er alloy resistor is based on the resistance characteristics of the resistive material. Alloy resistance is composed of conductive and resistive materials, and the addition of resistive materials changes the resistance value of alloy resistance. By selecting appropriate resistive materials, the stability of resistance values and temperature coefficients can be controlled.
Characteristics of EVER OHMS Alloy Resistance
1. High accuracy: The resistance value accuracy of alloy resistors can reach 0.1% or higher.
2. Good stability: The resistance value of the alloy resistor remains stable within a certain temperature range and is not easily affected by the external environment.
3. Low temperature coefficient: The temperature coefficient of alloy resistance is generally several tens of ppm/℃, and temperature changes have little impact on the resistance value.
The correct use of EVER OHMS Alloy Resistance
1. Choose the appropriate model and parameters: Select the appropriate alloy resistance model and parameters based on actual application needs. Common parameters include resistance value, power, accuracy, and temperature coefficient.
2. Connect the correct circuit: Connect the alloy resistor correctly into the circuit, paying attention to the connection between the pins at both ends of the resistor and the circuit.
3. Temperature compensation: Due to the small temperature coefficient of alloy resistance, it can be used for temperature compensation. In some applications, when the ambient temperature changes, compensation resistors are added to counteract the changes in resistance values, thereby maintaining the stability of the circuit.
4. Maintain good heat dissipation: The power of alloy resistors is generally relatively small, but it may also occur in some high-power applications. When using high-power alloy resistors, it is necessary to ensure that the alloy resistor does not overheat and provide a good heat dissipation environment or use a heat sink for heat dissipation.
5. Prevention of damage: Alloy resistors are relatively precise electronic components that are prone to damage such as electrostatic breakdown. When using alloy resistors, attention should be paid to preventing factors such as static electricity and overcurrent to avoid damaging the resistor.
Application Cases of EVER OHMS Alloy Resistance
1. Electronic equipment: Alloy resistors are widely used in various electronic devices, such as power supplies, amplifiers, sensors, etc. By selecting and connecting appropriate alloy resistors, the stability and accuracy requirements of the circuit can be achieved.
2. Temperature compensation: The temperature coefficient of alloy resistance is small and can be used for temperature compensation circuits. For example, adjusting the working point of the circuit by compensating the resistance to adapt to changes in environmental temperature and improve the stability of the circuit.
3. Measuring instrument: Alloy resistance is commonly used in measuring instruments to provide stable resistance values. For example, the resistance measurement function in a multi-purpose multimeter uses alloy resistance to provide accurate and reliable measurement results.
Alloy resistors have high accuracy, stability, and temperature coefficient, making them one of the indispensable components in electronic devices. The correct use of alloy resistors requires selecting appropriate models and parameters, connecting the correct circuit, compensating for temperature, maintaining good heat dissipation, and preventing damage. Alloy resistors are widely used in various electronic devices, such as power supplies, amplifiers, sensors, etc. They can provide stable and reliable resistance values, meeting the stability and accuracy requirements of circuits.
