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.). - ◯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 products that have received any excessive mechanical shock such as by being dropped. - ◯The performance of the product may deteriorate or at the worst case open if coating materials are used, thus please assess the situation beforehand by tak-ing this factor into consideration. - ◯Due to the application of mechanical stress after mounting and handling such as contact, disconnection may occur. - ◯Do not use for a purpose outside of the contents regulated in the delivery specifications. - ◯The products listed on this specification sheet (the “Products”) are intended for incorporation into automobile and/or equipment to be installed in automobile on the grounds that (i) the Products are used in accordance with the conditions and scope stated in this specification sheet and (ii) said automobile and/or equipment involving the Products are used under a normal operation and use condition. Except for said incorporation into automobile and/or equipment installed in automobile, the Products are not designed or warranted to meet the requirements of the applications listed below, whose performance and/or quality require a more stringent level of safety or reliability, or whose failure, malfunction or trouble could cause serious damage to society, person or property. Please understand that we are not responsible for any damage or liability caused by use of the Products in any of the applications listed below or for any other use exceeding the range or conditions set forth in this specification sheet. If you intend to use the Products beyond the condition and scope of this specification sheet or in any of the applications listed below, please contact with our sales office.
