Resin coating (Except DLW Series) Using resin for coating/molding products may affect the products performance. So please pay careful attention in selecting resin. Prior to use, please make the reliability evaluation with the product mounted in your application set. 2. Resin coating (DLW Series) The impedance 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 in selecting 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. 3. Caution for use (DLW/NFW Series) When you hold products with a tweezer, please hold by the sides. Sharp materials, such as a pair of tweezers, should not touch the winding portion to prevent breaking the wire. Mechanical shock should not be applied to the products mounted on the board to prevent breaking the core. 6 174

C31E.pdf 08.9.1 Lead Type EMIFILr !Caution/Notice ■ !Caution (Rating) Do not use products beyond the rated current and rated voltage as this may create excessive heat and deteriorate the insulation resistance. ■ !Caution (Soldering and Mounting) Mounting holes should be designed as specified in these specifications. Other designs than shown in these specifications may cause cracks in ceramics which may lead to smoking or firing. ■ Notice (Storage and Operating Conditions) 1. Do not use products in a chemical atmosphere such as chlorine gas, acid or sulfide gas. 2. Do not use products near water, oil or organic solvents. Avoid environment where dust or dirt may adhere to product. VFR3V series is designed only to absorb electrostatic surges. Do not use this product to absorb large energy surges such as lighting or switching related surges. 1. Storage Period Used the products within 12 months after delivery. Solderability should be checked if this period is exceeded. 2. Storage Conditions (1) Storage temperature: -10 to 40 degrees C Relative humidity: 30 to 70% Avoid sudden changes in temperature and humidity. (2) Do not store products in a chemical atmosphere such as chlorine gas, acid or sulfide gas. (3) When restoring taping type (BL01RN1A1F1J), please attach the Spacer between flanges of reel. The Spacer is corrugated paper which is attached when shipping. ■ Notice (Soldering and Mounting) 1. Washing Failure and degradation of a product are caused by the washing method. When you wash in conditions that are not in mounting information, please contact Murata engineering. 2. Soldering Reliability decreases with improper soldering methods. Please solder by the standard soldering conditions shown in mounting information. 3. Other Noise suppression levels resulting from Murata's EMI suppression filters "EMIFIL" may vary, depending on the circuits and ICs used, type of noise, mounting pattern, lead wire length, mounting location, and other operating conditions. Be sure to check and confirm in advance the noise suppression effect of each filter, in actual circuits, etc. before applying the filter in a commercial-purpose equipment design. 6 175
