Soldering time 3(+1,-0)s Time 2 times Note : Do not directly touch the products with the tip of the soldering iron in order to prevent the crack on the products due to the thermal shock. 11.5 Solder Volume ・ Solder shall be used not to be exceeded the upper limits as shown below. ・ Accordingly increasing the solder volume, the mechanical stress to Chip is also increased. Exceeding solder volume may cause the failure of mechanical or electrical performance. UpperLimit Recommendable t 1/3T≦t≦T T: thickness of product 11.6 Product’s location 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. [Products direction] a b Products shall be located in the sideways direction (Length: ab) to the mechanical stress. 〈Poorexample〉 〈Goodexample〉 (2)Components location on P.C.B. separation. It is effective to implement the following measures, to reduce stress in separating the board. It is best to implement all of the following three measures; however, implement as many measures as possible to reduce stress. Contents of Measures Stress Level (1) Turn the mounting direction of the component parallel to the board separation surface. A > D *1 (2) Add slits in the board separation part. A > B (3) Keep the mounting position of the component away from the board separation A > C surface. MURATA MFG.CO., LTD

Reference Only Spec No. JELF243B-0005R-01 P.8/9 C Perforation 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. Recommended Screw Hole 11.7 Cleaning Conditions Products shall be cleaned on the following conditions. (1) Cleaning temperature shall be limited to 60°C max. (40°C max for IPA.) (2) Ultrasonic cleaning shall comply with the following conditions with avoiding the resonance phenomenon at the mounted products and P.C.B. Power : 20 W/ l max. Frequency : 28kHz to 40kHz Time : 5 min max. (3) Cleaner 1. Alcohol type cleaner Isopropyl alcohol (IPA) 2. Aqueous agent PINE ALPHA ST-100S (4) There shall be no residual flux and residual cleaner after cleaning. In the case of using aqueous agent, products shall be dried completely after rinse with de-ionized water in order to remove the cleaner. (5) Other cleaning Please contact us. 11.8 Resin coating The inductance 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. 11.9 Caution for use There is possibility that the inductance value change due to magnetism. Don‘t use a magnet or a pair of tweezers with magnetism when chip coil are handled. (The tip of the tweezers should be molded with resin or pottery.) 11.10 Magnetic Saturation When the excessive current over rated current is applied, the inductance value may change due to magnetism.
