EVER OHMS alloy resistance selection considerations

EVER OHMS alloy resistor is an electronic component produced by Taiwan EVER OHMS Technology (Ever Ohms Co., Ltd.). With its high precision, good stability, high temperature resistance and other characteristics, it has been widely used in the fields of electronics, communications, home appliances, automobiles, aerospace and so on. The EVER OHMS alloy resistor is composed of conductive material and resistive material. The stability of resistance and temperature coefficient can be controlled by selecting suitable resistive material.

peculiarity
High accuracy: Resistance value accuracy can reach 0.1% or higher.
Good stability: the resistance value remains stable within a certain temperature range and is not easily affected by the external environment.
Small temperature coefficient: the temperature coefficient is generally tens of ppm/℃, and the effect of temperature change on the resistance value is small.
Correct use method
Select the appropriate model and parameters: According to the actual application requirements, select the appropriate alloy resistance model and parameters, including resistance value, power, accuracy and temperature coefficient.
Connect the correct circuit: properly connect the alloy resistor to the circuit, paying attention to the connection between the pins at both ends of the resistor and the circuit.
Temperature compensation: Because the temperature coefficient of the alloy resistance is small, it can be used for temperature compensation.
Maintain good heat dissipation: In high power applications, it is necessary to ensure that the alloy resistance does not overheat, providing a good heat dissipation environment or using a heat sink.
Prevent damage: Alloy resistor is a more precise electronic component, easy to be damaged by electrostatic breakdown, pay attention to prevent static electricity and overcurrent and other factors when using.
Application case
Electronic equipment: Alloy resistors are widely used in various electronic equipment, such as power supplies, amplifiers, sensors, etc.
Temperature compensation: can be used for temperature compensation circuit, through the compensation resistance to adjust the operating point of the circuit to adapt to environmental temperature changes, improve the stability of the circuit.
Measuring instruments: Commonly used in measuring instruments to provide stable resistance values.
EVER OHMS alloy resistance selection considerations
When selecting EVER OHMS alloy resistance, the following key parameters need to be considered:

Resistance value: First determine the required resistance value, usually in ohms (Ω), and select the appropriate resistance value according to the needs of the circuit.
Power: Choosing the right power level is also an important consideration in the selection process. The power range of EVER OHMS alloy resistors can range from 0.5W to 4W, and the specific selection should be based on the actual application requirements of the circuit and the expected operating conditions.
Accuracy: The accuracy of the resistance refers to the deviation between the actual resistance value and the nominal resistance value. According to the requirements of the circuit, it is very important to choose the appropriate accuracy level.
Temperature coefficient (TCR) : The temperature coefficient is the degree to which the resistance value changes with temperature. In some applications, such as signal processing circuits, resistors with low temperature coefficients need to be selected to ensure the stability and reliability of the circuit.
Package size: Select the appropriate package size according to the space limitation and installation method of the circuit design, such as patch resistance, four-terminal resistance, etc.
Special performance requirements: For example, for audio processing circuits, low noise, low distortion resistance may need to be selected; In the power amplifier circuit, it is necessary to choose a resistance with strong power tolerance.
Application scenario: The EVER OHMS resistor can be used in various application scenarios, such as current limiting, voltage dividing, and shunt. It can also be used for current detection, circuit calibration, current sharing, and load balancing.
