We have said before that the relationship between the insulation resistance of axial film capacitors and temperature, and the insulation resistance will decrease with the increase of temperature. Today we will talk about the relationship between the insulation resistance of axial film capacitors and the test voltage. The so-called test voltage refers to the voltage value applied to both ends of the capacitor when the axial film capacitor is tested. The relationship between the insulation resistance of the axial film capacitor and the voltage applied to both ends of the capacitor and the relationship between the insulation resistance of the capacitor's dielectric and the voltage. The test voltage of general axial film capacitors will be less than or equal to the rated voltage. When the rated voltage value of the axial film capacitor is less than 100V, the test voltage of the capacitor is 10V. When the rated voltage of the axial film capacitor is greater than or equal to 100V, the test voltage of the capacitor is 100V. When the rated voltage of the axial film capacitor is greater than or equal to 500V, the test voltage of the capacitor is 500V. For more details, please call 0755-85274135. As for the relationship between the insulation resistance of the axial film capacitor and the ambient humidity: when the dielectric and auxiliary materials of the axial film capacitor are damp, the insulation resistance of the capacitor will be significantly reduced. Although today's manufacturing technology has been greatly developed, the axial film capacitor products are very airtight, but in order for the capacitor and the circuit to operate normally and safely, it is necessary to do a good job of moisture-proof work. If the capacitor is not tightly sealed, the humidity of the surrounding environment will affect the insulation resistance of the capacitor.
