■ PRECAUTIONS
＊This catalog contains the typical specication only due to the limitation of space. When you consider the purchase of our products, please check our specication.
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 specication are intended for use in general electronic equipment,(ofce 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 (trafc 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
◆Design
1. Please design insertion pitches as matching to that of leads of the component on PCBs.
Technical
consider-
ations
◆Design
1. When Inductors are mounted onto a PC board, hole dimensions on the board should match the lead pitch of the component, if not, it will cause breakage of
the terminals or cracking of terminal roots covered with resin as excess stress travels through the terminal legs.
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
◆Adjustment of mounting machine
1. When installing products, care should be taken not to apply distortion stress as it may deform the products.
4. Soldering
Precautions
◆Wave soldering
1. Please refer to the specications in the catalog for a wave soldering.
2. Do not immerse the entire inductor in the ux during the soldering operation.
◆Lead free soldering
1. When using products with lead free soldering, we request to use them after conrming adhesion, temperature of resistance to soldering heat, soldering etc
sufciently.
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.
◆Reow soldering
1. As for reow soldering, please contact our sales staff.
Technical
consider-
ations
◆Lead free soldering
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.
5. Cleaning
Precautions
◆Cleaning conditions
1. CAL type, LH type, LA Type
Please do not do cleaning by a supersonic wave.
Technical
consider-
ations
◆Cleaning conditions
1. CAL type, LH type, LA Type
If washing by supersonic waves, supersonic waves may deform products.
6. Handling
Precautions
◆Handling
1. Keep the inductors away from all magnets and magnetic objects.
◆Mechanical considerations
1. Please do not give the inductors any excessive mechanical shocks.
2. LH type
If inductors are dropped onto the oor or a hard surface they should not be used.
◆Packing
1. Please do not give the inductors any excessive mechanical shocks.
In loading, please pay attention to handling indication mentioned in a packing box (a loading direction / number of maximum loading / fragile item).
Technical
consider-
ations
◆Handling
1. There is a case that a characteristic varies with magnetic inuence.
◆Mechanical considerations
1. There is a case to be damaged by a mechanical shock.
2. LH type
There is a case to be broken by a fall.
◆Packing
1. There is a case that a lead wire could be deformed by a fall or an excessive 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, inductors should be used within one year from the time of delivery.
In case of storage over 6 months, solderability shall be checked before actual usage.
Technical
consider-
ations
◆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.
