automotive powertrain control system, train control system, and ship control system, traffic signal equipment,
medical equipment classified as Class III by IMDRF).
Please do not incorporate our products into any equipment requiring high levels of safety and/or reliability (e.g.,
aerospace equipment, aviation equipment*, medical equipment classified as Class IV by IMDRF, nuclear control
equipment, undersea equipment, military equipment).
*Note: There is a possibility that our products can be used only for aviation equipment that does not directly affect the safe operation of aircraft (e.g.,
in-flight entertainment, cabin light, electric seat, cooking equipment) if such use meets requirements specified separately by TAIYO YUDEN.
Please be sure to contact TAIYO YUDEN for further information before using our products for such aviation equipment.
When our products are used even for high safety and/or reliability-required devices or circuits of general electronic
equipment, it is strongly recommended to perform a thorough safety evaluation prior to use of our products and to
install a protection circuit as necessary.

■PRECAUTIONS
1．Circuit Design
Precautions
◆Operating environment
1. The products listed in this catalogue are intended for use in general electronic equipment
(e.g., AV equipment, OA equipment, home electric
appliances, office equipment, information and communication equipment), general medical
equipment, industrial equipment, and automotive
interior applications, etc.
Please be sure to contact TAIYO YUDEN for further information before using the products for any equipment which may directly cause
loss of human life or bodily injury (e.g., specially controlled medical equipment, transportation equipment including, without limitation,
automotive powertrain control system, train control system, and ship control system, traffic signal equipment).
Please do not incorporate our products into any equipment requiring high levels of safety and/or reliability (e.g., aerospace equipment,
aviation equipment, nuclear control equipment, undersea equipment, military equipment, etc.).
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.
▶ 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/) .
hq_i_wound_CB_LB_prec_e.doc
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 term
inal 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, These series should be used within 6 months from the time of delivery.
Technical
considerations
◆Storage
1. Under a high temperature a
nd humidity environment, problems such as reduced solderability caused by oxidation of terminal electrodes
and deterioration of taping/packaging materials may take place.
