An inductor is a component that converts electrical energy into magnetic energy and stores it, similar to a transformer, but with only one winding. An inductor has a certain inductance, which only blocks changes in current. If the inductor is in a state where no current is flowing through it, it will try to block the flow of current through it when the current is turned on; if the inductor is in a state where there is current flowing through it, it will try to maintain the current flow when the circuit is turned off.
Inductors mainly play the functions of filtering, oscillation, delay, and notch in the circuit, as well as filtering signals, filtering noise, stabilizing current, and suppressing electromagnetic interference.
The most common role of inductors in circuits is to form an LC filter circuit together with capacitors. Capacitors have the characteristic of "blocking DC and passing AC", while inductors have the function of "passing DC and blocking AC". If the DC current with many interference signals is passed through the LC filter circuit, then the interference signal will be converted into heat energy by the inductor and consumed; when the relatively pure DC current passes through the inductor, the AC interference signal will also be turned into magnetic induction and Thermal energy and higher frequency are most likely to be impeded by the inductor, which can suppress high-frequency interference signals.
The inductor has the characteristic of preventing alternating current from passing through and allowing direct current to pass smoothly. The higher the frequency, the greater the coil impedance. Therefore, the main function of an inductor is to isolate and filter AC signals or to form a resonant circuit with capacitors, resistors, etc.
Key application areas for inductors include:
Power electronics, filtering and signal processing, wireless communications, magnetic storage, electric motors and transformers, timing and oscillation, automotive electronics, etc.
Quality is a company's consistent commitment to excellence in its operations. We have established a strict and standardized quality inspection process. Suppliers, quality inspection teams, and after-sales quality return visits are all important parts of the process.
Establish quality requirements for purchased products, regularly check suppliers to see if they continue to meet quality standards, and conduct evaluation audits on potential suppliers to ensure that they must meet the necessary quality standards.
The quality inspection team first conducts pre-purchase audits or inspections to ensure that the products sold to customers meet the standards. Inspect products for potential defects or non-conforming parts and record inspection results. Substandard products are rejected and suppliers are re-evaluated for continued cooperation.
Based on customer feedback to measure overall customer satisfaction with a product or reset, develop an action plan based on customer feedback to address problem areas.
Quality inspection of internal products and processes:
1. Develop a quality control plan that includes provisions for checking products and processes.
2. Establish procedures to investigate non-conformities and perform root cause analysis.
3. Develop a corrective action system to follow up non-conformities and corrective actions.
Customer quality inspection:
1. Establish a system to track customer feedback and change requests.
2. Establish a process for listening to customer feedback and taking appropriate action.
