How to choose the magnetic ring inductance for popular science switching power supply
Magnetic ring inductors for switching power supplies are familiar to us. As a widely used inductor, we can see it in many electronic products. The hot issues in the application of magnetic ring inductors for switching power supplies must be inseparable from how to select the type. This article will briefly discuss how to select a magnetic ring inductor for a switching power supply.
Many people think that it is very simple to choose magnetic ring inductors for switching power supplies. It is enough to find the corresponding magnetic ring inductors for switching power supplies according to the performance parameters provided by the technicians. It's not as simple as you think. Inductor products seem simple, but the actual selection work is very complicated. The selection of magnetic ring inductance for switching power supply is not as simple as finding the corresponding inductance that meets the requirements with the performance parameters provided by technicians. The selection of magnetic ring inductance for switching power supply depends on whether it can be installed on the circuit board correctly, whether the test results after installation meet the standards, and whether it will affect the normal operation of other electronic components.
1. Can it be installed correctly on the circuit board:
To put it simply, we are checking whether the package size can be selected correctly. If the size is too large and exceeds the reserved space of the circuit board, it cannot be installed; if the size is too small, the installation may not be firm. These two different situations will directly affect enterprise usage. Therefore, the package size selection must be correct!
2. Whether the test and analysis results are up to standard:
Testing is an important part of the selection process, and only testing can determine whether the inductor selection meets the needs. During the test, pay close attention to the abnormal data in the test, because these abnormal data represent the problems of the inductance products, which need to be analyzed and confirmed by professional technicians.
3. Does it affect the work of other electronic components?
This is the problem of inductance compatibility. If the magnetic ring inductance for switching power supply is not compatible with other electronic components, it is necessary to replace the inductance application.
