How to distinguish the quality of color ring inductors 2

3. Testing accuracy: Use testing instruments to test inductors and check the accuracy of their measurement results. A good inductor should have high measurement accuracy and a small error range. It can be verified for accuracy by comparing it with other devices with known inductance values. If the test results deviate from expectations or do not match the specifications, it may indicate poor quality of the inductor.  diode

4. Frequency characteristics: The frequency characteristics of an inductor are also an important indicator. A good inductor should have a wide operating frequency range and be able to maintain stable inductance values at different frequencies. The frequency characteristics of an inductor can be evaluated by measuring its inductance value at different frequencies. If the inductance value of an inductor fluctuates significantly within a certain frequency range, it may indicate poor frequency characteristics.

5. Durability: Inductors typically require long-term use, so durability is also a key factor. A good inductor should have a long service life and be able to operate normally under different environmental conditions. diode
