■ Product information in this catalog is as of October 2011. All of the contents specified herein are subject to change
without notice due to technical improvements, etc. Therefore, please check for the latest information carefully be-
fore practical application or usage of the Products.
Please note that Taiyo Yuden Co., Ltd. shall not be responsible for any defects in products or equipment incorpo-
rating such products, which are caused under the conditions other than those specified in this catalog or individual
specification.
■ Please contact Taiyo Yuden Co., Ltd. for further details of product specifications as the individual specification is
available.
■ Please conduct validation and verification of products in actual condition of mounting and operating environment
before commercial shipment of the equipment.
■ All electronic components or functional modules listed in this catalog are developed, designed and intended for
use in general electronics equipment.(for AV, office automation, household, office supply, information service,
telecommunications, (such as mobile phone or PC) etc.). Before incorporating the components or devices into any
equipment in the field such as transportation,( automotive control, train control, ship control), transportation signal,
disaster prevention, medical, public information network (telephone exchange, base station) etc. which may have
direct influence to harm or injure a human body, please contact Taiyo Yuden Co., Ltd. for more detail in advance.
Do not incorporate the products into any equipment in fields such as aerospace, aviation, nuclear control, subma-
rine system, military, etc. where higher safety and reliability are especially required.
In addition, even electronic components or functional modules that are used for the general electronic equipment,
if the equipment or the electric circuit require high safety or reliability function or performances, a sufficient reliabil-
ity evaluation check for safety shall be performed before commercial shipment and moreover, due consideration to
install a protective circuit is strongly recommended at customer's design stage.
■ The contents of this catalog are applicable to the products which are purchased from our sales offices or distribu-
tors (so called “TAIYO YUDEN’s official sales channel”).
It is only applicable to the products purchased from any of TAIYO YUDEN’ s official sales channel.

LB-series are Wound Chip Inductors having wide line-up, which are suitable
for any circuit designs.
◦LBC series has large rated current. They contribute to the miniatur-
ization of the power supply circuit.
◦LBR series has low DC resistance. They contribute to the miniaturiza-
tion of the power supply circuit.
◦LBMF series has a low loss characteristic.
◦
They are suitable for an anti-noise measure on the power supply circuit
of DSC, DVC, HDD, LCD-TV, mobile phones,PC, game equipments,
various communication equipments and etc..

■ PRECAUTIONS
＊ This catalog contains the typical specification only due to the limitation of space. When you consider the purchase of our products, please check our specification.
For details of each product (characteristics graph, reliability information, precautions for use, and so on), see our Web site (http://www.ty-top.com/) or CD catalogs.
1．Circuit Design
Precautions
◆Operating environment
1． The products described in this specification are intended for use in general electronic equipment,(office supply equipment, telecommunications systems,
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
Precautions ◆Land pattern design
1．Please contact any of our offices for a land pattern, and refer to a recommended land pattern of a right figure or specifications.

ations
PRECAUTIONS
【Recommended Land Patterns】
Surface Mounting
・ Mounting and soldering conditions should be checked beforehand.
・ Applicable soldering process to those products is reflow soldering only.
3．Considerations for automatic placement
Precautions
◆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.
Technical
consider-
ations
1. When installing products, care should be taken not to apply distortion stress as it may deform the products.
4．Soldering
Precautions
◆Wave soldering （LEM Type only）
1．For wave soldering,please apply conditions meeting the range of the specifed conditions in our catalog or the relevant specifications.
◆Reflow soldering （LB and CB Types）
1．For reflow soldering with either leaded or lead-free solder,the profile specified in "point for controlling" is recommended.
◆Reflow soldering （LEM）
1．For reflow soldering, please apply conditions meeting the range of the specified conditions in our catalog or the relevant specifications.
◆Recommended conditions for using a soldering iron
1．Put the soldering iron on the land-pattern. Soldering iron's temperature - Below 350℃ Duration-3 seconds or less. The soldering iron shoud not come in contact
with inductor directly.
Technical
consider-
ations
◆Wave soldering （LEM Type only）
1．Components can be damaged by excessive heat where soldering conditions exceed the specified range.
◆Reflow soldering （LB and CB Types）
1．Reflow profile
◆Recommended conditions for using a soldering iron
1．Components can be damaged by excessive heat where soldering conditions exceed the specified range.
5．Cleaning
Precautions ◆Cleaning conditions
Washing by supersonic waves shall be avoided.
Technical
consider-
ations
◆Cleaning conditions
If washed by supersonic waves, the products might be broken.
6．Handling
Precautions
◆Handling
1．There is a case that a characteristic varies with magnetic influence.
◆Breakaway PC boards （splitting along perforations）
1．Planning pattern configurations and the position of products should be carefully performed to minimize stress.
◆Mechanical considerations
1．There is a case to be damaged by a mechanical shock.
Technical
consider-
ations
◆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
Precautions
◆Storage
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.
Technical
consider-
ations
◆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：0～40℃　／　Humidity：Below 70% RH
The ambient temperature must be kept below 30℃ even under 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：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.
