Publish Time: 2024-07-01
The saturation current and temperature rise characteristics of Common Mold Integrated Chip Inductor are crucial to its normal operation and performance in the circuit. Here are some common test methods.
When testing the saturation current, you can use a DC power supply and an electronic load. Connect the common mode inductor to the circuit, gradually increase the DC current through the inductor, and monitor the voltage across the inductor. When the voltage begins to drop significantly, the corresponding current value is the saturation current. During the test, make sure that the increase in current is slow and steady to obtain accurate results.
For the test of temperature rise characteristics, a thermocouple or infrared thermometer is usually required. First, select a suitable measurement point on the surface of the inductor, install a thermocouple or use an infrared thermometer to align the measurement point. Then, let the inductor run continuously for a period of time at a certain working current, and record the temperature values at different times. In order to obtain more reliable data, multiple tests can be performed under different working conditions (such as different currents and ambient temperatures).
In actual testing, the following points should also be noted. It is necessary to ensure the stability of the test environment and avoid external factors from interfering with the test results. At the same time, the precision and accuracy of the test instrument also need to be calibrated and verified. In addition, the test can be carried out by simulating the actual working circuit. This can more realistically reflect the performance of the inductor in actual applications.
It can also be combined with theoretical calculation and simulation analysis. By establishing a mathematical model of the inductor, calculating the expected saturation current and temperature rise, and comparing and verifying with the actual test results, it is helpful to deeply understand the characteristics of the inductor.
In short, testing the saturation current and temperature rise characteristics of Common Mold Integrated Chip Inductor requires the comprehensive use of appropriate test equipment and methods, and strict control of test conditions to obtain accurate and reliable test data, providing strong support for circuit design and application.
