Top tape or cover tape 165°~ 180° Base tape Fig. 6.1-5 6.2 Storage a. The solderability of the external electrode may be deteriorated if packages are stored where they are exposed to high humidity. Package must be stored at 40℃ or less and 70% RH or less. b. The solderability of the external electrode may be deteriorated if packages are stored where they are exposed to dust of harmful gas (e.g. HCl, sulfurous gas of H2S) c. Packaging material may be deformed if package are stored where they are exposed to heat of direct sunlight. d. Minimum packages, such as polyvinyl heat-seal packages shall not be opened until they are used. If opened, use the reels as soon as possible. e. Solderability shall be guaranteed for 12 months from the date of delivery on condition that they are stored at the environment specified in specification. .For those parts, which passed more than 12 months shall be checked solder-ability before use. 7. Warning and Attentions 7.1 Precautions on Use a. Always wear static control bands to protect against ESD. b. Any devices used (soldering iron, measuring instruments) should be properly grounded. c. Use non-magnetic tweezers when handing the chips. d. Pre-heating when soldering, and refer to the recommended condition specified in specification. e. Don’t apply current in excess of the rated current value. It may cause damage to components due to over-current. f. Keep clear of anything that may generate magnetic fields such as speakers, coils. g. When soldering, the electrical characteristics may be varied due to hot energy and mechanical stress. h. When coating products with resin, the relatively high resin curing stress may change the electrical characteristics. For exterior coating, select resin carefully so that electrical and mechanical performance of the product is not affected. Before using, please evaluate reliability with the product mounted in your application set. i. When mount chips with adhesive in preliminary assembly, do appropriate check before the soldering stage, i.e., the size of land pattern, type of adhesive, amount applied, hardening of the adhesive on proper usage and amounts of adhesive to use. j. Mounting density: Add special attention to radiating heat of products when mounting other components nearby. The excessive heat by other products may cause deterioration at joint of this product with substrate. k. Since some products are constructed like an open magnetic circuit, narrow spacing between components may cause magnetic coupling. l. Please do not give the product any excessive mechanical shocks in transportation. m. Please do not touch wires by sharp terminals such as tweezers to avoid causing any damage to wires. n. Please do not add any shock and power to the soldered product to avoid causing any damage to chip body. o. Please do not touch the electrodes by naked hand as the solderability of the external electrodes may deteriorate by grease or oil on the skin. 7.2 PCB Bending Design The following shall be considered when designing and laying out PCB’s. a. PCB shall be designed so that products are not subjected to the mechanical stress from board warp or deflection. Products shall be located in the sideways direction to the (Poor example) b. (Good example) mechanical stress. Products location on PCB separation. C Separation B Product shall be located carefully because they may be subjected to the mechanical stress in order of A>C=B>D. A D Sunlord c. Categories: general confidential Wire Wound Chip Ceramic Inductor Page 10 of 14 When splitting the PCB board, or insert (remove) connector, or fasten thread after mounting components, care is required so as not to give any stress of deflection or twisting to the board. Because mechanical force may cause deterioration of the bonding strength of electrode and solder, even crack of product body. Board separation should not be done manually, but by using appropriate devices. 7.3 Recommended PCB Design for SMT Land-Patterns When chips are mounted on a PCB, the amount of solder used (size of fillet) and the size of PCB Land-Patterns can directly affect chip performance (such as Q). And they can also cause other soldering question (such as offset and side lap). Therefore, the following items must be carefully considered in the design of solder land patterns. a. Please use the PCB pad and solder paste we recommend, and contact us in advance if they need to be changed. b. Please use flux contained with resin since the highly acidic (Chlorine content more than 0.2 wt%) or water-soluble one could damage the insulation film of wires, then causing short circuit of parts. c. The amount of solder applied can affect the ability of chips to withstand mechanical stresses which may lead to breaking or cracking. Therefore, when designing land-patterns it is necessary to consider the appropriate size and configuration of the solder pads which in turn determines the amount of solder necessary to form the fillets. d. When more than one part is jointly soldered onto the same land or pad, the pad must be designed that each component’s soldering point is separated by solder-resist. Recommended land dimensions please refer to product specification. 8. Recommended Soldering Technologies This product is only for reflow soldering and iron soldering. 8.1 Re-flowing Profile △ Preheat condition: 150~200℃/60~120sec. △ Allowed time above 217C: 60~90sec. △ Max temp: 260℃ △ Max time at max temp: 10sec. △ Solder paste: Sn/3.0Ag/0.5Cu △ Allowed Reflow time: 2 times max.

Categories: general confidential Wire Wound Chip Ceramic Inductor Page 11 of 14 Accordingly increasing the solder volume, the mechanical stress to chip is also increased.Exceeding solder volume may cause the failure of mechanical or electrical performance. Before soldering, please ensure that the solder should not adhere to the wire part of chip. Please pay particular attention to whether there is flux remaining on surface of the wire part of chip after subjected to reflow soldering since this may causing short circuit of parts. 10.
