Reference Only Spec No.JELF243C-0015T-01 P.11/12 12.8 Resin coating When products are coated with resin, please contact us in advance. 12.9 Handling of a substrate (1)There is a possibility of chip cracking caused by PCBexpansion/contraction with heat, because stress on a chip is different depending on PCB material and structure. When the thermal expansion coefficient greatly differs between the board used for mounting and the chip, it will cause cracking of the chip due to the thermal expansion and contraction. The chip is assumed to be mounted on the PCB of glass-epoxy material, and we don't test with other PCB material which has different thermal expansion coefficient from Glass-epoxy. When other PCB materials are considered, please be sure to evaluate by yourself. (2)After mounting products on a substrate, do not apply any stress to the product caused by bending or twisting to the substrate when cropping the substrate, inserting and removing a connector from the substrate or tightening screw to the substrate. Excessive mechanical stress may cause cracking in the product. In case of the mounting on flexible PCB, there is a possibility of chip cracking caused by mechanical stress even from small bending or twisting. When the flexible PCB is considered, please be sure to evaluate by yourself. Bending Twisting 12.10 Storage and Handing Requirements (1) Storage period Use the products within 12 months after delivered. Solderability should be checked if this period is exceeded. (2) Storage conditions ・Products should be stored in the warehouse on the following conditions. Temperature : -10°C ~ 40°C H umidity : 15% to 85% relative humidity No rapid change on temperature and humidity. ・Products should not be stored on bulk packaging condition to prevent the chipping of the core and the breaking of winding wire caused by the collision between the products. ・Products should be stored on the palette for the prevention of the influence from humidity, dust and so on. ・Products should be stored in the warehouse without heat shock, vibration, direct sunlight and so on. (3) Handling Condition Care should be taken when transporting or handling product to avoid excessive vibration or mechanical shock. 13.!

Reference Only Spec No.JELF243C-0015T-01 P.12/12 <Ele ctrical Performance:Measuring Method of Inductance/Q> (1) Residual elements and stray elements of test fixture can be described by F-parameter shown in following. I1 I2 A B Zm V1 V2 Zx C D V1 = A B V2 I 1 C D I 2 Test Head Test fixture Product (2) The impedance of chip coil Zx and measured value Zm can be described by input/output current/voltage. V V Zm= 1 Zx= 2 I 1 , I 2 (3) Thus,the relation between Zx and Zm is following; Zm-β where, α= D / A =1 Zx= α 1-ZmΓ β= B / D =Zsm-(1-Yom Zsm)Zss Γ= C / A =Yom Zsm:measured impedance of short chip Zss:residual impedance of short chip (0.480nH) Yom:measured admittance when opening the fixture (4) Lx and Qx shall be calculated with the following equation. Im(Zx) Im(Zx) Lx :Inductance of chip coil Lx= Qx= 2πf , Re(Zx) Qx:Q of chip coil f :Measuring frequency MURATA MFG.CO., LTD
