Soldering Conditions Products can be applied to reflow soldering. (1) Flux,Solder Flux Use rosin-based flux, but not highly acidic flux (with chlorine content exceeding 0.2(wt)%. ) Do not use water-soluble flux. Solder Use Sn-3.0Ag-0.5Cu solder Standard thickness of solder paste : 100 µm to 200 μm (2) Soldering conditions • Pre-heating should be in such a way that the temperature difference between solder and ferrite surface is limited to 150℃ max. Also cooling into solvent after soldering should be in such a way that the temperature difference is limited to 100℃ max. Insufficient pre-heating may cause cracks on the ferrite, resulting in the deterioration of product quality. • 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. MURATA MFG.CO., LTD. Reference Only Spec.

Reworking with soldering iron • Pre-heating: 150°C, 1 min • Tip temperature: 350°C max. • Soldering time : 3 (+1, -0) seconds. • Soldering iron output: 80W max. • Tip diameter: φ3mm max. • Times : 2times max. Note: Do not directly touch the products with the tip of the soldering iron in order to prevent the crack on the ferrite material due to the thermal shock. 9-4. Solder Volume Solder shall be used not to be exceed as shown below. Upper Limit Recommendable 1/3T≦t≦T (T: Chip thickness) t Accordingly increasing the solder volume, the mechanical stress to product is also increased. Exceeding solder volume may cause the failure of mechanical or electrical performance. 9-5. 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 for board warpage. a Products shall be located in the sideways direction (Length: a D *1 A > B A > C C B D A Slit *1 A > D is valid when stress is added vertically to the perforation as with Hand Separation. If a Cutting Disc is used, stress will be diagonal to the PCB, therefore A > D is invalid. (3) Mounting Components Near Screw Holes When a component is mounted near a screw hole, it may be affected by the board deflection that occurs during the tightening of the screw. Mount the component in a position as far away from the screw holes as possible. Screw Hole Recommended 9-6. Mounting density Add special attention to radiating heat of products when mounting the inductor near the products with heating. The excessive heat by other products may cause deterioration at joint of this product with substrate. 9-7. Operating Environment Do not use this product under the following environmental conditions, on deterioration of the Insulation Resistance of the Ferrite material and/or corrosion of Inner Electrode may result from the use. (1) in the corrodible atmosphere such as acidic gases, alkaline gases, chlorine, sulfur gases, organic gases and etc (the sea breeze, Cl2, H2S, NH3, SO2, NO2,etc) (2) in the atmosphere where liquid such as organic solvent, may splash on the products. (3) in the atmosphere where the temperature / humidity changes rapidly and it is easy to dew. 9-8. 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.
