■ 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/)

1. Circuit Design
Precautions
◆Operating env
ironment
1. The products described in this specification are intended for use in general electronic equipment,(office supply equipment, telecommunications systems,
mea
suring equipment, and household equipment). They are not intended for use in mission-critical equipment or systems requiring special quality and high
rel
iability (traffic systems, safety equipment, aerospace systems, nuclear control systems and medical equipment including life-support systems,) where
pro
duct 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.
Tec

con
sider-
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 t
erminals or cracking of terminal roots covered with resin as excess stress travels through the terminal legs.
3. Considerations for automatic placement
Precautions
◆Adjustment of mo
unting 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.

◆Adjustment
of mo
unting 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 specifications in the catalog for a wave soldering.
2.
Do not immerse the entire inductor in the flux during the soldering operation.
◆Lea
d free soldering
1.
When using products with lead free soldering, we request to use them after confirming adhesion, temperature of resistance to soldering heat, soldering etc
suf
ficiently.
Recommended con
ditions for using a soldering iron:
・Put the soldering iron on the land-pattern.
・So
ldering iro
n's temperature - Below 350℃
・Duration - 3 sec
onds or less
・The soldering iron should not directly touch the inductor.
◆Refl
ow soldering
1.
As for reflow soldering, please contact our sales staff.

◆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 p
roducts.
5. Cleaning
Precautions
◆Cleaning con

conditions
1. CAL type, LH type, LA Ty

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.
◆Mec
hanical con
siderations
1. Please do not give the inductors any excessive mechanical shocks.
2.
LH type
If i
nductors are dropped onto the floor or a hard surface they should not be used.
◆Pac
king
1.
Please do not give the inductors any excessive mechanical shocks.
In l
oading, please pay attention to handling indication mentioned in a packing box (a loading direction / number of maximum loading / fragile item).

◆Handling
1.
There is a case that a characteristic varies with magnetic influence.
◆Mec
hanical con
siderations
1. There is a case to be damaged by a mechanical shock.
2.
LH type
Th
ere is a case to be broken by a fall.
◆Pac
king
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 co
ntrolled.
R
ecommended con
ditions
・Ambient tem
perature 0～40℃
・Humidity Bel
ow 70% RH
The ambient temperature must be kept below 30℃. Ev
en 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.
I
n case of storage over 6 months, solderability shall be checked before actual usage.
Tec

ations
◆Storage
1.
Under a high temperature and humidity environment, problems such as reduced solderability caused by oxidation of terminal electrodes and deterioration of
tap
ing/packaging materials may take place.
