Terms concerning chip coils
A resistance on a direct current.
A higher resistance makes higher power loss, then service life of the
battery will be shorter. |
For resonant circuits or impedance matching circuits:
Lower resistance is desirable.
For chokes: Lower resistance is desirable. |
Frequency at which the coil resonant with
self-capacitance.
Coil does not work as a coil over the self-resonant frequency. |
For resonant circuits or impedance matching circuits:
Higher frequency than the operating frequency is desirable.
For chokes: Higher frequency than the operating frequency is desirable.
|
The maximum value of the direct current that may flow
through a coil with no deterioration of the component.
If a current over the allowable current flows, excessive heat will be
possible to be generated and the quality will be impossible to be
guaranteed. |
| For chokes: The allowable current must be greater than
the maximum working current on the circuit. |
| Operating temperature range |
The allowable range of the environmental temperature
around a coil.
It does not contain the naturally generated heat. |
For resonant circuits or impedance matching circuits:
Must fit the operating temperature range of the set.
For chokes: Must fit the operating temperature range of the set. |
