Five New General FAQ for Ferrite Cores

Q: What causes heat generation of ferrite cores during operation?

A: Core loss and copper loss from winding are the main heat sources. High frequency and excessive current will increase loss and lead to temperature rise.

Q: Can ferrite magnetic rings work stably in humid environments?

A: Yes. Finished cores are insulated and moisture-proof treated. They feature good environmental adaptability and will not fail easily under normal humid conditions.

Q: What is the service life of Mn-Zn ferrite cores?

A: Ferrite cores have extremely low aging rate. Under rated temperature and load conditions, they can maintain stable performance for long-term service with almost no attenuation.

Q: Does more winding turns mean better filtering effect?

A: Moderate more turns improve impedance and noise suppression. However, excessive turns will increase parasitic capacitance and affect high-frequency filtering performance.

Q: Can ferrite cores be used for both AC and DC circuits?

A: Yes. Ferrite magnetic rings are widely used in AC-DC hybrid circuits. They effectively suppress high-frequency interference while ensuring normal DC and low-frequency current transmission.
