Inductors

Q I would like to know about DC resistance. What kind of affect does the DC resistance have on the characteristics of the power supply?
Q I would like to know about the DC superimposing characteristics. How does the DC superimposing characteristics affect the characteristics of the power supply?
Q I would like to know how to specify the rated current.
Q What power inductor should be selected in order to improve the efficiency of the power supply?
Q Why is the Q characteristics of the LQW (wire wound type RF inductor) better than the LQP and LQG?
Q Tell me about the L value steps of Murata RF inductors.
Q How can I check the inductance value and Q value at a certain frequency?
Q What are the differences between the LQP03TN and LQP03TG series?
Q What is the difference between the rated voltage and withstand voltage (absolute maximum voltage)?
Q Why is the withstand voltage (absolute maximum voltage) specified for DFE (wire wound metal alloy) but not for LQH (wire wound ferrite)?
Q The max. and typ. values are given for the rated current (based on inductance change / based on temperature rise). However, the max. value is lower than the typ. value in the values given. What does this notation mean?
Q How do I select an RF inductor?

Q What is the status of the ISO certification acquisition?
