WIRE-WOUND CHIP POWER INDUCTORS (CB SERIES)
REFLOW
■ FEATURES
■ APPLICATIONS
CB-series are Wound Chip Inductors having wide line-up, which are suitable
for any circuit designs.
◦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..
◦CBC series has large rated current. They contribute to the miniaturization of the power supply circuit.
◦CBL series has low profile characteristic. They contribute to the lowering of the equipments.
◦CBMF series has a low loss characteristic.
■ OPERATING TEMP.
◦－ 40 ～ 105℃（Including-self-generated heat）

■ PRECAUTIONS
LEM Type，LB Type，CB Type
1．Circuit Design
◆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
Precautions
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
Precautions
1．Please contact any of our offices for a land pattern, and refer to a recommended land pattern of a right figure or specifications.
PRECAUTIONS
Technical 【Recommended Land Patterns】
considerSurface Mounting
ations
・Mounting and soldering conditions should be checked beforehand.
・Applicable soldering process to those products is reflow soldering only.
3．Considerations for automatic placement
◆Adjustment of mounting machine
Precautions
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- 1. When installing products, care should be taken not to apply distortion stress as it may deform the products.
ations
4．Soldering
◆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.
Precautions ◆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.
◆Wave soldering（LEM Type only）
1．Components can be damaged by excessive heat where soldering conditions exceed the specified range.

5．Cleaning
Precautions
Technical
considerations
◆Cleaning conditions
Washing by supersonic waves shall be avoided.
◆Cleaning conditions
If washed by supersonic waves, the products might be broken.
6．Handling
◆Handling
1．There is a case that a characteristic varies with magnetic influence.
◆Breakaway PC boards（splitting along perforations）
Precautions
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.
◆Handling
1．Keep the inductors away from all magnets and magnetic objects.
Technical ◆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.
consider2．Board separation should not be done manually, but by using the appropriate devices.
ations
◆Mechanical considerations
1．Please do not give the inductors any excessive mechanical shocks.
7．Storage conditions
◆Storage
Precautions
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.
◆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
Technical
Ambient temperature：0～40℃　／　Humidity：Below 70% RH
considerThe ambient temperature must be kept below 30℃ even under ideal storage conditions, solderability of products electrodes may decrease as time passes. For
ations
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.
