I N D U C T O R S January 2015 Inductors for Power Circuits Wound Ferrite VLCF Series VLCF5020 Type VLCF5020 (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. SAFETY REMINDERS Please pay sufficient attention to the warnings for safe designing when using these products. REMINDERS The storage period is less than 6 months. Be sure to follow the storage conditions (Temperature: 5 to 40°C, Humidity: 10 to 75% RH or less). If the storage period elapses, the soldering of the terminal electrodes may deteriorate. Do not use or store in locations where there are conditions such as gas corrosion (salt, acid, alkali, etc.). 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 does not exceed 150°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 shortening may occur. 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 the overall distortion of the printed circuit board and partial distortion such as at screw tightening portions. Self heating (temperature increase) occurs when the power is turned ON, so the tolerance should be sufficient for the set thermal design. Carefully lay out the coil for the circuit board design of the non-magnetic shield type. A malfunction may occur due to magnetic interference. Use a wrist band to discharge static electricity in your body through the grounding wire. Do not expose the products to magnets or magnetic fields. Do not use for a purpose outside of the contents regulated in the delivery specifications.
