Caution 10.1 Restricted applications Please contact us before using our products for the applications listed below which require especially high reliability for the prevention of defects which might directly cause damage to the third party's life, body or property. (1) Aircraft equipment (6) Disaster/crime prevention equipment (2) Aerospace equipment (7) Traffic signal equipment (3) Undersea equipment (8) Transportation equipment (trains, ships, etc.) (4) Power plant control equipment (9) Data-processing equipment (5) Medical equipment (10) Applications of similar complexity and/or reliability requirements to the applications listed in the above 10.2 Precautions on rating Do not use the products in excess of their rated current. Doing so may cause the product to generate heat, resulting in short circuit between inner electrodes, wire breakage, or melted solder, which may cause dropping of parts. 10.3 Fail-safe Be sure to provide an appropriate fail-safe function on your product to prevent a second damage that may be caused by the abnormal function or the failure of our product. 11. Precautions for Use This product is designed to be mounted by soldering. If you want to use other mounting method, for example, using a conductive adhesive, please consult us beforehand. Also, if repeatedly subjected to temperature cycles or other thermal stress, due to the difference in the coefficient of thermal expansion with the mounting substrate, the solder (solder fillet part) in the mounting part may crack. The occurrence of cracks due to thermal stress is affected by the size of the land where mounted, the solder volume, and the heat dissipation of the mounting substrate. Carefully design it when a large change in ambient temperature is assumed. 11.1 Land dimensions The following diagram shows the recommended land dimensions for flow and reflow soldering. a 0.7 b 2.0 c 0.7 (in mm) 11.2 Flux and solder used Flux • Use a rosin-based flux. • Do not use a highly acidic flux with a halide content exceeding 0.2(wt)% (chlorine conversion value). • Do not use a water-soluble flux. Solder • Use Sn-3.0Ag-0.5Cu solder. • Standard thickness of solder paste: 100 μm to 150 μm If you want to use a flux other than the above, please consult our technical department. MURATA MFG CO., LTD Spec No.: JELF243B_9126C P6/9 11.3 Soldering conditions (flow, reflow) • Pre-heating should be in such a way that the temperature difference between solder and product surface is limited to 150°C max. Cooling into solvent after soldering also should be in such a way that the temperature difference is limited to 100°C max. Insufficient pre-heating may cause cracks on the product, 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. (1) Flow Temp. (℃) 265℃±3℃ 250℃ Limit Profile 150 Heating Time 60s min. Standard Profile Time. (s) Standard profile Limit profile Pre-heating 150°C/60 s min. 150°C/60 s min.

(s) Standard profile Limit profile Pre-heating 150°C to 180°C/90 s±30 s 150°C to 180°C/90 s±30 s Heating Above 220°C/30 s to 60 s Above 230°C/60 s max. 245°C±3°C 260°C/10 s 2 times 2 times Peak temperature Number of reflow cycles MURATA MFG CO., LTD Spec No.: JELF243B_9126C P7/9 11.4 Reworking with soldering iron The following requirements must be met to rework a soldered product using a soldering iron. Item Requirement Pre-heating 150°C/approx. 1 min Tip temperature of soldering iron 350°C max. Power consumption of soldering iron 80 W max. Tip diameter of soldering iron Soldering time ø3 mm max. 3 s (+1 s, -0 s) Number of reworking operations 2 times max. * Avoid a direct contact of the tip of the soldering iron with the product. Such a direction contact may cause cracks in the ceramic body due to thermal shock. 11.5 Solder volume Solder shall be used not to be exceeded the upper limits as shown below. An increased solder volume increases mechanical stress on the product. Exceeding solder volume may cause the failure of mechanical or electrical performance. 11.6 Product's location The following shall be considered when designing and laying out PCBs. (1) PCB shall be designed so that products are not subject to mechanical stress due to warping the board. [Products direction] Products shall be located in the sideways direction (length: a < b) to the mechanical stress. a b 〈 Poor example〉 〈 Good example〉 (2) Components location on PCB 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 surface. A>C *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. MURATA MFG CO., LTD Spec No.: JELF243B_9126C P8/9 (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. 11.7 Handling of substrate 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. Bending Twisting 11.8 Cleaning The product shall be cleaned under the following conditions. (1) The cleaning temperature shall be 60°C max. If isopropyl alcohol (IPA) is used, the cleaning temperature shall be 40°C max. (2) Perform ultrasonic cleaning under the following conditions. Exercise caution to prevent resonance phenomenon in mounted products and the PCB. Item Requirement Power Time 20 W/L max. 5 min max. Frequency 28 kHz to 40 kHz (3) Cleaner Alcohol-based cleaner: IPA Aqueous agent: PINE ALPHA ST-100S (4) There shall be no residual flux or residual cleaner. When using aqueous agent, rinse the product with deionized water adequately and completely dry it so that no cleaner is left. * For other cleaning, consult our technical department. 11.9 Storage and transportation Storage period Use the product within 6 months after delivery. If you do not use the product for more than 6 months, check solderability before using it. Storage conditions • The products shall be stored in a room not subject to rapid changes in temperature and humidity. The recommended temperature range is -10°C to +40°C. The recommended relative humidity range is 15% to 85%. Keeping the product in corrosive gases, such as sulfur, chlorine gas or acid may cause the poor solderability. • Do not place the products directly on the floor; they should be placed on a palette so that they are not affected by humidity or dust. • Avoid keeping the products in a place exposed to direct sunlight, heat or vibration. • Avoid storing the product by itself bare (i.e. exposed directly to air). Transportation Excessive vibration and impact reduces the reliability of the products. Exercise caution when handling the products. 11.10 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. MURATA MFG CO., LTD Spec No.: JELF243B_9126C P9/9 11.11 Handling of product Inductance could change due to the effect of magnetism. Do not use magnetized tweezers, magnets, or other similar tools when handling the product (instead, use tweezers with resin or ceramic tips). 11.12 Magnetic saturation A current exceeding the rated current could cause the inductance value to drop due to magnetic saturation. 12.
