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. Temp. 260℃ (℃) 245℃±3℃ 230℃ 220℃ Limit Profile 180 150 Standard Profile 30s～60s 60s max 90s±30s Time(s) Standard Profile Limit Profile Pre-heating 150～180°C 、90s±30s Heating above 220°C、30s～60s above 230°C、60s max.

SpecNo.JELF243A-0053T-01 R e f e r e n c e O n l y P7/8 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 Products shall be located in the sideways b direction (Length:a<b) to the mechanical stress. 〈Poor example〉 〈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 A > D ∗1 the board separation surface. (2) Add slits in the board separation part. A > B (3) Keep the mounting position of the component away from A > C the board separation surface. C Seam B ∗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 D the PCB, therefore A > D is invalid. b A Slit Length:a<b a (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 Screw Hole Recommended in a position as far away from the screw holes as possible. 11.7 Cleaning Conditions Products shall be cleaned on the following conditions. But, Products can be used without cleaning,too. (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 minutes max. (3) Cleaner 1. Alternative cleaner ・sopropyl 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-ionizedwater in order to remove the cleaner. (5) Other cleaning Please contact us. 11.8 Resin coating The inductance value may change due to high cure-stress of resin to be used for coating/molding products. An open circuit issue may occur by mechanical stress caused by the resin, amount/cured shape of resin, or operating condition etc. Some resin contains some impurities or chloride possible to generate chlorine by hydrolysis under some operating condition may cause corrosion of wire of coil, leading to open circuit. So, please pay your careful attention when you select resin in case of coating/molding the products with the resin.Prior to use the coating resin, please make sure no reliability issue is observed by evaluating products mounted on your board. 11.9 Temperature rating of the circuit board and components located around Temperature may rise up to max. 40 ℃ when applying the rated current to the Products. Be careful of the temperature rating of the circuit board and components located around. MURATA MFG.CO., LTD

Excessive mechanical stress may cause cracking in the product. Bending Twisting 11.12 Storage and Handling 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 ~ 40°C Humidity : 15 to 85% relative humidity No rapid change on temperature and humidity The electrode of the products is coated with solder. Don't keep products in corrosive gases such as sulfur, chlorine gas or acid, or it may cause oxidization of electrode, resulting in poor solderability. ・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. 12.
