11. Measuring method for common mode impedance.
Measured common mode impedance may be included measurement error due to stray capacitance,
residual inductance of test fixture.
To correct this error, the common mode impedance should be calculate as follows;
(1) Measure admittance of the fixture(opened), Go Bo.
(2) Measure impedance of the fixture(shorted), Rs Xs.
(3) Measure admittance of the specimen, Gm Bm.
(4) Calculate corrected impedance Z using the formula below.
Z = (Rx2+Xx2) 1/2
Where
Gm-Go
Rx = (Gm-Go)2 + (Bm-Bo)2
- Rs
-(Bm- Bo)
Xx = (Gm-Go) 2 + (Bm-Bo)2

16. Notice
This product is designed for solder mounting.
Please consult us in advance for applying other mounting method such as conductive adhesive.
16.1 Flux and Solder
Use rosin-based flux, but not highly acidic flux (with chlorine content exceeding 0.2(wt)%. )
Flux
Do not use water-soluble flux.
Use Sn-3.0Ag-0.5Cu solder.
Solder
Use of Sn-Zn based solder will deteriorate performance of products.
In case of using Sn-Zn based solder, please contact Murata in advance.
16.2 Assembling
Pre-heating should be in such a way that the temperature difference between solder and
ceramic surface is limited to 100°C MAX. Also cooling into solvent after soldering
should be in such a way that the temperature difference is limited to 100°C max.
16.3 Resin coating
The impedance value may change and/or it may affect on the product's performance due to high cure-stress of
resin to be used for coating / molding products. So please pay your careful attention when you select resin. In
prior to use, please make the reliability evaluation with the product mounted in your application set.
16.4 Attention regarding P.C.B. bending
The following shall be considered when designing and laying out P.C.B.'s.
(1) P.C.B. shall be designed so that products are not subject to the mechanical stress due to warping the board.

(2) Soldering Conditions
Standard soldering profile and the limit soldering profile is as follows.
The excessive limit soldering conditions may cause leaching of the electrode and / or resulting
in the deterioration of product quality.
•On flow soldering (e.g. double wave soldering), use the product in consideration of the
conditions of solder, solder temperature and immersion time (melting time) because longer
soldering time may cause the corrosion of the electrode.
•On dipping soldering, use the product in consideration of the conditions of solder,
solder temperature, flux, preheat and so on because de-wetting may be caused.
