(2/9) I N D U C T O R S REMINDERS FOR USING THESE PRODUCTS Before using these products, be sure to request the delivery specifications. n SAFETY REMINDERS e Please pay sufficient attention to the warnings for safe designing when using these products. e b REMINDERS e The storage period is less than 6 months. Be sure to follow the storage conditions (Temperature: 5 to 30°C, Humidity: 10 to 75% RH or v less). If the storage period elapses, the soldering of the terminal electrodes may deteriorate. a n Do not use or store in locations where there are conditions such as gas corrosion (salt, acid, alkali, etc.). h o Before soldering, be sure to preheat components. The preheating temperature should be set so that the temperature difference between the solder temperature and chip temperature r i does not exceed 150°C. o t c Soldering corrections after mounting should be within the range of the conditions determined in the specifications. If overheated, a short circuit, performance deterioration, or lifespan shoretening may ocucur. When embedding a printed circuit board where a chip is mounted to a set, be sure that residual stress is not given to the chip due to b d the overall distortion of the printed circuit board and partial distortion such as at screw tightening portions. o Self heating (temperature increase) occurs when the power is turned ON, so the tolerance should be sufficient for the set thermal l design. l r Carefully lay out the coil for the circuit board design of thei non-magneticp shield type. w A malfunction may occur due to magnetic interference. Use a wrist band to discharge static electricity in your body througdh the grounding wire. Do not expose the products to magnets or magnsetic fields. e t Do not use for a purpose outside of the contents regulatedp in the delivery specifications. c The products listed on this catalog are intended for use in general electronic equipment (AV equipment, telecommunications p equipment, home appliances, amusemeunt equipment, computer equipment, personal equipment, office equipment, measurement equipment, industrial robots) under da normal operaotion and use condition. The products are not designed or warranted to meet the requirements of the applications listed below, whose performance and/or quality require a more stringento level of safety tor reliability, or whose failure, malfunction or trouble could cause serious damage to society, person or property. s If you intend to use the prodructs in the applications listed below or if you have special requirements exceeding the range or conditions set forth in the each cataplog, please contact us.
