I N D U C T O R S April 2016 Inductors for Power Circuits Wound Ferrite CLF-NI-D Series CLF7045NI-D Type CLF7045NI-D (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 12 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. 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. Do not use products that have received any excessive mechanical shock such as by being dropped. 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. Do not expose the products to magnets or magnetic fields. The performance of the product may deteriorate if coating materials are used, thus please assess the situation beforehand by taking this factor into consideration. Do not use for a purpose outside of the contents regulated in the delivery specifications.
