- *1: Inductance is measured at 1.0 MHz. 

- *2: Rated current defines actual value of DC current, when temperature rise of coil becomes 40 K. (Method A) 

- *3: Rated current (reference) defines actual value of DC current, when temperature rise of coil becomes 40 K. (Method B) 

- *4: Reference only 

- Method A (PANASONIC's standard measurement conditions), Method B (high heat dissipation measurement) is different from Method A by the measurement methods. In normal application condition, the part's temperature depends on circuit design and heat dissipation condition. This condition shall be verified by the worst operational condition. 

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.

**Matters to Be Observed When Using This Product / Reference Information** 

## **Matters to Be Observed When Using This Product** 

(Power inductor for consumer use) 

## **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 bobbin, 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. 

- The storage temperature of an inductor ranges from -5 ℃ to 35 ℃, and the working temperature (ambient temperature) of an inductor ranges from -40 ℃ to 130 ℃ (which includes the temperature increase). 

   - The highest working temperature of PCC-F126(N6) series is 100 ℃. 

## **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 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. 

## **Reference information** 

## ~~Cn~~ **Labeling on package** 

On the inductor package, a product number, the number of components, and the place of origin are indicated. Usually, the place of origin is written in English.
