Power : 20 W / l max. Frequency : 28kHz to 40kHz Time : 5 minutes max. - (3) Cleaner 1. Alternative 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 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 Caution for use** - ・Sharp material such as a pair of tweezers or other material such as bristles of cleaning brush, shall not be touched to the winding portion to prevent the breaking of wire. - ・ Mechanical shock should not be applied to the products mounted on the board to prevent the breaking of the core. ## **11.10 Handling of a 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 MURATA MFG.CO., LTD ## SpecNo.JELF243A-0039R-01 Reference P8/8 Only ~~oo Po~~ ## **11.11 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.** A **Note** (1) Please make sure that your product has been evaluated in view of your specifications with our product being mounted to your product.
