■ Storage Conditions
● Package
: Normal temperature (–5 to 35 °C), normal humidity (85 %RH max.), shall not be exposed to
direct sunlight and harmful gases and care should be taken so as not to cause dew.
● Operating Temperature : –40 to +85 °C
■ Storage Period
● Solderability may be reduced due to the conditions of high temperature and high humidity which causes the oxidation
of tin-plated terminals. Even if storage conditions are within specified limits, solderability may be reduced with the
passage of time. Therefore, please control the storage conditions and try to use the product within 6 months of receipt.
■Packaging Methods, Soldering Conditions and Safety Precautions
Please see Data Files.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.

■ Notes
● Solderability may be reduced due to the conditions of high temperature and high humidity which causes the oxidation
of tin-plated terminals. Even if storage conditions are within specified limits, solderability may be reduced with the
passage of time. Therefore, please control the storage conditions and try to use the product within 6 months of receipt.
● In case the product has been stored for a period longer than 6 months, use the product only after confirmation of its
solderability.

Fixed Inductors (Chip Inductors)
Safety Precautions
(Common precautions for Chip Inductors)
• When using our products, no matter what sort of equipment they might be used for, be sure to make a written
agreement on the specifications with us in advance. The design and specifications in this catalog are subject
to change without prior notice.
• Do not use the products beyond the specifications described in this catalog.
• This catalog explains the quality and performance of the products as individual components. Before use, check
and evaluate their operations when installed in your products.
• Install the following systems for a failsafe design to ensure safety if these products are to be used in equipment
where a defect in these products may cause the loss of human life or other significant damage, such as damage to
vehicles (au to mo bile, train, vessel), traffic lights, medical equipment, aerospace equipment, elec tric heating
appliances, combustion/gas equipment, rotating equipment, and disaster/crime prevention equipment.
✽ Systems equipped with a protection circuit and a protection device
✽ Systems equipped with a redundant circuit or other system to prevent an unsafe status in the event of a single fault
Precautions for use
1. Operation range and environments
1 These products are designed and manufactured for general and stan dard use in general elec tron ic
equipment (e.g. AV equipment, home electric applianc es, office equipment, information and com mu nication
equipment)
2 These products are not intended for use in the following special conditions. Before using the products, carefully check
the effects on their quality and performance, and determine whether or not they can be used.
• In liquid, such as water, oil, chemicals, or organic solvent
• In direct sunlight, outdoors, or in dust
• In salty air or air with a high concentration of corrosive gas, such as Cl2, H2S, NH3, SO2, or NO2
• In an environment where these products cause dew condensation
2. Handling
1 Do not bring magnets or magnetized materials close to the product. The influence of their magnetic field can
change the inductance value.
2 Do not apply strong mechanical shocks by either dropping or collision with other parts.
Excessive schock can damage the part.
3. Land pattern design
1 Please refer to the recommended land pattern for each type shown on the datasheet.
2 Avoid placing the chip inductor on any metal pattern except the recommended land pattern because a drop of Q
and mutual conductance may occur.
3 In case of flow soldering, venting of soldering flux gases should be made for high density assemblies to get a
good solder connection.
4 In case of reflow soldering, consider the layout because taller components close to chip inductor tend to block
thermal conduction.
4. Mounting
1 In general, magnetic and electric characteristics of ferrite cores can be changed by applying excessively strong
force. Placement force should not exceed 20 N.
2 Do not bend or twist the PWB after mounting the part.
5. Cleaning
1 Do not use acid or alkali agents. Some cleaning solvents may damage the part.
Confirm by testing the reliability in advance of mass production.
2 If Ultrasonic cleaning is used, please confirm the reliability in advance.
It is possible that combined resonance of component and PWB and cavitation can cause an abnormal vibration
mode to exist causing damage.
6. Caution about applying excessive current
The rated current is defined as the smaller value of either the current value when the inductance drops 10 %
down from the initial point or the current value when the average temperature of coil inside rises 20 °C up from
the initial point. Do not operate product over the specific max. current.
Package markings include the product number, quantity, and country of origin.
In principle, the country of origin should be indicated in English.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.
