Q.
Please explain how an inductor (a coil) functions.
Q.
What is the Q value of an inductor (a coil)?
Q.
Why is inductance specified by numbers such as 1, 1.5, 2.2, 3.3, etc.?
Q.
What is SRF (self-resonant frequency)?
Q.
Please explain the types of inductors (coils) and their differences.
Q.
Would it be safe to use an inductor in which a current exceeding the rated current flows momentarily?
Q.
Would it be a problem to use inductors in parallel?
Q.
Please provide a basic explanation of the process for choosing an inductor.
Q.
There are direction identification markings on some products. What are those markings for?
Q.
I would like to use high frequency inductors for impedance matching. Which products do you recommend?
Q.
I do not understand how the direction identification markings on the MLG/MHQ series inductors correspond to each other.
Q.
Which inductor is recommended for smoothing a power circuit?
Q.
Why are the characters such as "4R7" or "100" printed on some products?

Messwerte

Q.
When I measured the inductance of another company's product that is supposed to have the same inductance, it showed a different value. Why is that?

Technische Parameter

Q.
Where can I see the inductance value for the frequency at which I would like to use the inductor?
Q.
Please explain the specifying condition for the inductance value of a multilayer inductor for high frequency circuits.
Q.
Please explain the specifying condition for the rated current of a multilayer inductor for high frequency circuits.
Q.
Do multilayer inductors for high frequency circuits experience a decrease in inductance due to DC current (DC bias characteristics)?
Q.
Please explain the specifying conditions for the rated current of inductors for power circuits (Power Inductors).
Q.
What is the DC bias characteristic of an inductor for power circuits?
Q.
In there aging?

Umweltverträglichkeit

Q.
Do the inductor products of TDK support lead-free soldering?

Produktqualität und Betriebsdauer

Q.
What is the FIT (Failures in Time) of your inductors?

Struktur, Material

Q.
What is the Gigaspira structure of multilayer inductors? Please explain its features.
Q.
Since it seems that inductors for high frequency circuits uses dielectric ceramics as the their material, I am concerned about magnetic flux leaking out.
Q.
Please explain the types of core materials for inductors for power circuits (Power Inductors) and the characteristic differences among them.
Q.
What is a "magnetic shield type" inductor for power circuits?
Q.
Does singing become an issue with inductors, as in the case of multilayer ceramic capacitors? If so, what countermeasures can be taken?
Q.
How can I check each product for compliance with AEC-Q200 (an automotive electronics standard)?
