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 YUDENs official sales channel).

■PRECAUTIONS
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.
Technical
considerations
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
considerations 1. When installing products, care should be taken not to apply distortion stress as it may deform the products.
4．Soldering
Precautions
◆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.
◆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
should not come in contact with inductor directly.
Technical
considerations
◆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
considerations
◆Cleaning conditions
If washed by supersonic waves, the products might be broken.

i_wound_CB_LB_prec_e-01
6．Handling
Precautions
◆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.
Technical
considerations
◆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.
7．Storage conditions
Precautions
◆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,
LB type：Should be used within 6 months from the time of delivery.
Technical
considerations
◆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.
