(1)Please make sure that your product has been evaluated in view of your specifications with our product being
mounted to your product.
(2)You are requested not to use our product deviating from the reference specifications.
(3)The contents of this reference specification are subject to change without advance notice.
Please approve our product specifications or transact the approval sheet for product specifications
before ordering.
To keep compatibility to other vender’s product, Inductance and Q value shall be measured in following method.
(1) Residual elements and stray elements of test fixture can be described by F-parameter shown in following.
(2) The impedance of chip coil Zx and measured value Zm can be described by input/output current/voltage.
(3) Thus,the relation between Zx and Zm is followin
Where, α＝D/A＝1
β＝B/D＝Zsm－（1－YomZsm）Zss
Γ＝C/A＝Yom
Zsm:measured impedance of short chip
Zss:residual impedance of short chip (=equivalent series Inductance X)
Yom:measured admittance when opening the fixture
Important: X:Zss shall be defined as correction value to fit nominal inductance of other venders’ products.
Please input X value instead of equivalent series Inductance (ShortL) on test equipment calibration.
(4) Lx and Qx shall be calculated with the following equation.
Im(Zx) Im(Zx)
f :Measuring frequency
2πf ， Re(Zx)
Inductance and Q value shall be measured after this calibration setting.
In addition, Q value should be measured under our standard calibration setting of residual impedance, 0.771nH.
