Fixed inductors are electronic components used to measure current, voltage and resistance, and are widely used in various electrical devices and systems. In order to ensure the quality and performance of fixed inductors, a series of product standards have been formulated so that manufacturers and users have a unified reference when selecting and using fixed inductors.

Secondly, the product standards for fixed inductors also include electrical performance requirements. Fixed inductors should have stable inductance and resistance values and be able to maintain good performance within a certain operating temperature range. In addition, the insulation resistance, withstand voltage and temperature resistance of fixed inductors should also meet the corresponding standard requirements to ensure that they can work normally under various environmental conditions.

In addition, the product standards for fixed inductors also include reliability and durability requirements. Fixed inductors should have good anti-seismic, anti-vibration and anti-interference capabilities, and be able to work stably and reliably in harsh working environments. In addition, the life and reliability of fixed inductors should also meet the corresponding standard requirements to ensure that they can work stably for a long time.

Finally, the product standards for fixed inductors also include environmental protection and safety requirements. Fixed inductors should comply with relevant environmental regulations and standards, contain no harmful substances, and not pollute the environment. In addition, the safety performance of fixed inductors should also comply with the corresponding standard requirements to ensure that users will not be subject to electric shock or other safety risks during use.

In general, the product standards of fixed inductors cover multiple aspects such as appearance, size, electrical performance, reliability, durability, environmental protection and safety to ensure that their quality and performance can meet the needs of users. Manufacturers and users should strictly abide by these product standards when selecting and using fixed inductors to ensure that fixed inductors can work stably and reliably, providing guarantee for the normal operation of electrical equipment and systems.
