Matters to Be Observed When Using This Product

This product is not designed for use in special environments. Do not use in the following special environments or conditions

as performance may be affected. If you use this product, please thoroughly verify its performance and reliability at your own

risk.

(1) Use in environments directly exposed to water, salt water, or oil, or in liquids such as water, oil, chemicals, or organic

solvents.

(2) Use in an environment exposed to direct sunlight such as outdoor exposure, ozone, radiation or ultraviolet rays, or dust.

(3) Use in a place with large amounts of moisture (Condensation, water leakage, etc.), sea breeze, corrosive gases such

as Cl2, H2S, NH3, SO2, NOX, etc.

(4) Environment filled with toxic gases (Hydrogen sulfide, sulfurous acid, nitrous acid, chlorine and its compounds,

bromine and its compounds, ammonia, etc.)

(5) Use in an acidic or alkaline environment.

(6) Use in an environment where the voltage exceeds HBM (2 kV), MM (200 V) or where there are strong

electromagnetic waves.

(7) Use solvents, water, water-soluble detergents, etc. for soldering and flux cleaning after soldering.

(8) Use after sealing or coating the product with resin, etc.

(9) Use when shock or stress is applied by dropping or excessive loading.

■ 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.

■ Do not use this product in circuit conditions where the voltage load exceeds the specified dielectric strength.

■ 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.

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.

■ 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.
