Matters to Be Observed When Using This Product
Matters to Be Observed When Using This Product
(Power inductor for Automotive)
Use environments and cleaning conditions
■ This product (inductor) is intended for standard general-purpose use in electronic equipment, and is not designed for
use in the specific environments described below. Using the product in such specific environments or service conditions,
therefore, may affect the performance of the product.
Please check with us about the performance and reliability of the product first before using the product.
(1) A product splashed with water, coffee, etc., is in a wet state.
(2) Used in a place where the product is heavily exposed to sea breeze or a corrosive gas, such as Cl2, H2S, NH3, SO2,
or NOX.
(3) Used in an outdoor environment where the product is exposed to direct sunlight, ozone, radiation, UV-rays, etc.,
or in a dusty place.
■ Sealing the product with a resin may damage the copper wire insulation cover of the product. In such a case, consult
us first.
■ Immersing the product in a solvent, cleaning agent, or coating agent containing toluene or xylene for a long period
may result in a significant drop in the performance of the product. In such a case, consult us first.
Response to anomalies and handling conditions
■ The inductor, as a single component, does not have a protective function against a problem such as overloading,
short circuit, or open failure. Make sure to provide a circuit set with a protection device or circuit that protects the inductor,
and confirm that smoke generation/ignition, weakened dielectric strength, lower insulation resistance, etc., do not occur.
■ The temperature rise rate of the inductor changes depending on the state in which the inductor is incorporated in the
circuit set. Make sure to confirm that the temperature of the inductor is equal to or lower than the temperature
corresponding to the specified insulation class (heat-resistant class) when the inductor is incorporated in the circuit set.
■ Applying voltage higher than the specified withstand voltage to the inductor at a dielectric strength test leads to the
deterioration of the insulation performance of the inductor. Be careful to avoid this.
■ Handle the inductor while protecting it from static electricity with proper electrostatic control measures.
(Process/equipment) Applying voltage equal to or higher than 200 V to the inductor may change its characteristics.
Keep voltage applied to the inductor lower than 200 V.
■ The inductor having received mechanical stress as a result of dropping on the floor, etc., may have formed a crack on
its core, etc., and therefore the performance of the inductor may have dropped significantly. Avoid using such an
inductor.
■ When severe mechanical stress is applied to an inductor, its core may chip or crack.
There are also some cases where the core already has a chipped or cracked part. However, this chip or crack is
negligible and has no effect on the quality of the inductor.
Reliability and product life
A product conforming to "AEC-Q200" refers to a product having passed some or all of the evaluation test items defined
in AEC-Q200. To know the detailed specifications of individual products or specific evaluation test scores, please contact us.
We issue a delivery specification sheet for each product ordered. Please confirm with the sheet when you place an order
with us.

Matters to Be Observed When Using This Product / Reference Information
Circuit design and circuit board design
■ When the inductor is used in a different product set among a series of similar product sets, there are times when the
inductor will fail to achieve 100% of its capability because of the difference in service conditions, etc. In such a case,
consult us first.
■ When the inductor is used in an audible frequency range (= about 20 Hz to 20 kHz) or burst mode, it may emit a sound
(beat) under certain operation conditions (current waveform conditions). This sound may be heard as noise, depending
on circuits/board configurations in which the inductor is incorporated. Check for this problem before using the inductor.
■ When there is a possibility that electrostatic noise is applied to circuit components, place an ESD preventing component,
such as a capacitor resistant to static electricity, in a preceding stage to the inductor. In such a case, consult us first.
■ To ensure insulation between the internal coil of the inductor and the upper surface of the board, avoid forming patterns
or vias in which voltage exceeding the guaranteed operating voltage is applied, on the uppermost layer of the board in
counter to the inductor bottom. (DUST series)
■ Do not form a pattern, via, etc., on the counter to the bottom of the inductor. (MC series/* Fig.1, Dust type/*Fig.2)
■ Keep a component placed around the inductor from being in contact with the surface (top face, side face) of the inductor.
(MC series/* Fig. 3)
■ Different from a ferrite core type with a magnetic energy concentration gap, the inductor described herein has a vertical
leakage flux distribution.
Exercise special caution when using a component or a circuit configuration susceptible to leakage flux from an inductor.
