Safety Precautions
(Common precautions for Voltage Step-up Coils)
• 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 (automobile, train, vessel), traffic lights, medical equipment, aerospace equipment, electric heating
appliances, combustion/gas equipment, rotating equipment, and disaster/crime prevention equipment.
½
Systems equipped with a protection circuit and a protection device
½
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 appliances, office equipment, information and com munication
equipment)
2
These products are not designed for the 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 Cl
2
, H
2
S, NH
3
, SO
2
, or NO
2
• In an environment where these products cause dew condensation
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.
1
Resoldering should be done within 3 seconds by soldering iron, the temperature with 350 °C or less and should be cooling
down after ward. Both side of terminals shall be fixed closely to PWB. And terminals shall not be pressed in heating.
Don’t Press
2. Handling
3. Resoldering with a soldering iron
2
The wiring tab shall not be held by sharp-edged tool.
Wiring Tab
3
Iron shall not be put to the component itself.
4. Mounting side
1
External force must be less than 4.9N while mounting.
2
The wiring tab is expose the terminal, so please be careful when you design PWB pattern of coil
circumference.
5. Cleaning
If you clean the inductor, please use own your ultrasonic cleaning to check specified conditions.
6. Storage conditions
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.
<Package markings>
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.
