injury damage. such uses, contact TAIYO YUDEN Sales Department advance. 2.PCB Design Land pattern design 1.Please contact offices land pattern, refer recommended land pattern specifications. 3.Considerations automatic placement Adjustment mounting machine 1.Excessive impact load should imposed products when mounting onto boards. 2.Mounting soldering conditions should checked beforehand. 4.Soldering Wave soldering 1.Please refer specifications catalog wave soldering. Reflow soldering 1.Please contact offices reflow soldering, refer recommended condition specified. 2.LER012 Type,LB Type Reflow solderring only. Lead free soldering 1.When using products with lead free soldering, request them after confirming adhesion, temperature resistance soldering heat, etc. sufficiently. Recommended conditions using soldering iron soldering iron land-pattern. Soldering iron's temperature Below Duration seconds less soldering iron should directly touch inductor. 5.Cleaning Cleaning conditions Type 1.Washing supersonic waves shall avoided. 6.Handling Handling 1.Keep inductors away from magnets magnetic objects. Breakaway boards (splitting along perforations) 1.When splitting board after mounting inductors, care should taken give stresses deflection twisting board. 2.Board separation should done manually, using appropriate devices. Mechanical considerations 1.Please give inductors excessive mechanical shocks. 7.Storage conditions Storage 1.To maintain solderability terminal electrodes keep packing material good condition, temperature humidity storage area should controlled. Recommended conditions Ambient temperature Humidity Below Under high temperature humidity environment, problems such reduced solderability caused oxidation terminal electrodes deterioration taping/packaging materials take place. 1.There case damaged mechanical shock. 1.Planning pattern configurations position products should carefully performed minimize stress. 1.There case that characteristic varies with magnetic influence. Type 1.If washing supersonic waves, supersonic waves cause broken products. 1.If products used beyond range recommended conditions, heat stresses deform products, consequently degrade reliability products. When installing products, care should taken apply distortion stress deform products.
ambient temperature must kept below Even under ideal storage conditions, solderability products electrodes decrease time passes. this reason, type inductors should used within year from time delivery. type, type Please should used within months from time delivery. type case storage over months, solderability shall checked before actual usage.
