Power Choke Coil (Automotive Grade)
Application Guidelines (Automotive grade)
Safety precautions
・ 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.
✽ 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. Provision to abnormal condition
This power choke coil itself does not have any protective function in abnormal condition such as overload,
short-circuit and open-circuit conditions, etc.
Therefore, it shall be confirmed as the end product that there is no risk of smoking, fire, dielectric withstand
voltage, insulation resistance, etc. in abnormal conditions to provide protective devices and/or protection circuit
in the end product.
2. Temperature rise
Temperature rise of power choke coil depends on the installation condition in end products. It shall be confirmed
in the actual end product that temperature rise of power choke coil is in the limit of specified temperature class.
3. Dielectric strength
Dielectric withstanding test with higher voltage than specific value will damage Insulating material and shorten
its life.
4. Water
This Power choke coil must not be used in wet condition by water, coffee or any liquid because insulation
strength becomes very low in such condition.
5. Potting
If this power choke coil is potted in some compound, coating material of magnet wire might be occasionally
damaged. Please ask us if you intend to pot this power choke coil.
6. Model
When this power choke coil is used in a similar or new product to the original one, it might be unable to satisfy
he specifications due to difference of condition of usage.
Please ask us if you use this power choke coil in the manner such as above.
7. Drop
If the power choke coil receives mechanical stress such as drop, characteristics may become poor (due to
damage on coil bobbin, etc.). Never use such stressed power choke coil.
8. Buzz Noise
When this coil is used in the frequency band of the audible range (≒ 20 Hz to 20 kHz), or, when using in
burst mode, depending on the operating conditions (conditions of the energized waveform) sounds (buzz noise)
may occur. Depending on the circuit / board installation environment it may be heard as abnormal sounds,
so please check in advance.
9. Solvent (Series MC)
If this power choke coil is dipped in the cleaning agent, and the coating agent of the toluene and the xylene
system, there is a possibility that the performance decreases greatly. Please ask us if you intend to pot this power
choke coil.
10. Static electricity measures (Series MC)
①Circuit design
Please set up the ESD measures parts such as capacitors in the former steps of this power choke coil for static
electricity when there is a possibility that static electricity is impressed to the choke coil on the circuit.
Moreover, please consult our company about such a case once.

Power Choke Coil (Automotive Grade)
②Treatment with single
Take countermeasures against static electricity when using single power choke coil. (process and equipment)
There is a possibility that the characteristic changes when the voltage of 200 V or more is impressed to this
power choke coil. Please handle 200 V or less.
11. Printed circuit board design
①Land pattern and Via which exceed Operating Voltage, should not be placed top layer PWB under the products
for keeping isolation between inside coil and surface of PWB. (Series DUST)
②To the opposing part in this power choke coil bottom please install neither pattern nor the beer, etc. (Series MC)

④This power choke coil is different from the ferrite core-type that installs general concentration GAP.
It has the leakage magnetic bunch distribution of the choke coil to the vertical direction. Please be cautious
when using parts and circuit compositions which are easily affected by the leakage flux.
12. Other using emviroment
This power choke coil is not designed for the use in the following, special environment.
Therefore, please do not use it in the following special environment.
・Use in place where a lot of causticity gases such as sea breeze, Cl2, H2S, NH3, SO2, and NOx exist.
・Use in place where out-of-door exposure and direct sunshine strike.
13. Core Chipping and Core Crack
This choke coil has a possibility to make partial chipping or crack in the core due to excessive mechanical stress
from outside, and might have initially a partial chipping and/or cracks that do not affect the quality.
14. Keeping environment
If this power choke coil is kept under following environment and condition, there is a possibility that the
performance and soldering decreases greatly.
・Keep in place where a lot of causticity gases such as sea breeze, Cl2, H2S, NH3, SO2, and NOx exist.
・Keep in place where out-of-door exposure and direct sunshine strike.
