For rated current of ordinary small power choke coils, please refer to the rated current 1 in the above table. Rated current 2 is the current for instantaneous flow such as plunging current of DC/DC converter. In case of usage in the circuit where large current may be semicontinuously applied over 5 minutes with auto recovery circuit, etc., please contact our sales section before practical application. Rated current 1 : Current value to guarantee -30L of nominal inductance Rated current 2 : Current value to guarantee component temperature within TW40C with current flow. ( It is not the current to guarantee the inductance value.)

PRECAUTIONS
LEM Type LB Type CB Type
Precautions Operating environment, 1.The products described in this specification are intended for use in general electronic equipment,(office systems, supply Technical considerations
Stages 1.Circuit Design
equipment,
telecommunications
measuring
equipment, and household equipment). They are not intended for use in mission-critical equipment or systems requiring special quality and high reliability (traffic systems, safety equipment, aerospace systems, nuclear control systems and medical equipment including life-support systems,) where product failure might result in loss of life, injury or damage. For such uses, contact TAIYO YUDEN Sales Department in advance. 2.PCB Design Land pattern design 1.Please contact any of our offices for a land pattern, and refer to a recommended land pattern of specifications. 3.Considerations for automatic placement Adjustment of mounting machine 1.Excessive impact load should not be imposed on the products when mounting onto the PC boards. 2.Mounting and soldering conditions should be checked beforehand. 4.Soldering Wave soldering 1.Please refer to the specifications in the catalog for a wave soldering. Reflow soldering 1.Please contact any of our offices for a reflow soldering, and refer to the recommended condition specified. 2.LB Type, CB Type Reflow solderring only. Lead free soldering 1.When using products with lead free soldering, we request to use them after confirming of adhesion, temperature of resistance to soldering heat, etc. sufficiently. Recommended conditions for using a soldering iron Put the soldering iron on the land-pattern. Soldering iron's temperature - Below 350 Duration - 3 seconds or less The soldering iron should not directly touch the inductor. 5.Cleaning Cleaning conditions LB Type, CB Type 1.Washing by supersonic waves shall be avoided. 6.Handling Handling 1.Keep the inductors away from all magnets and magnetic objects. Breakaway PC boards (splitting along perforations) 1.When splitting the PC board after mounting inductors, care should be taken not to give any stresses of deflection or twisting to the board. 2.Board separation should not be done manually, but by using the appropriate devices. Mechanical considerations 1.Please do not give the inductors any excessive mechanical shocks. 7.Storage conditions Storage 1.To maintain the solderability of terminal electrodes and to keep the packing material in good condition, temperature and humidity in the storage area should be controlled. Recommended conditions Ambient temperature Humidity 0 40 1. Under a high temperature and humidity environment, problems such as reduced solderability caused by oxidation of terminal electrodes and deterioration of taping/packaging materials may take place. 1.There is a case to be damaged by a mechanical shock. 1.Planning pattern configurations and the position of products should be carefully performed to minimize stress. 1.There is a case that a characteristic varies with magnetic influence. LB Type, CB Type 1.If washing by supersonic waves, supersonic waves may cause broken products. 1.If products are used beyond the range of the recommended conditions, heat stresses may deform the products, and consequently degrade the reliability of the products. 1. When installing products, care should be taken not to apply distortion stress as it may deform the products.

Below 70% RH Even under
The ambient temperature must be kept below 30
ideal storage conditions, solderability of products electrodes may decrease as time passes. For this reason, LE type inductors should be used within one year from the time of delivery. LB type Please should be used within 6 months from the time of delivery. LE type In case of storage over 6 months, solderability shall be checked before actual usage.
