- *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.

## **2. Precautions for use** 

## **2-1. 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. 

## **2-2. 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. 

## **2-3. Dielectric strength** 

Dielectric withstanding test with higher voltage than specific value will damage Insulating material and shorten its life. 

## **2-4. 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. 

## **2-5. 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. 

## **2-6. Solvent** 

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. 

## **2-7. Static electricity measures** 

## ① Circuit 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. 

## ② Treatment with single 

(Processes and Equipment) If a voltage of 200 V or more is applied to the power choke coil, the characteristics may change. Take measures against static electricity when handling the power choke coil alone. Operate at 200 V or less.

## **2-8. 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. 

## **2-9. Storage temperature** 

- 5 ℃ to +35 ℃ 

## **2-10. Operating temperature** 

Minimum temperature ： ‒40 ℃ (Ambient temperature of the power choke coil) Maximum temperature ： 130 ℃ (Ambient temperature of the power choke coil plus the temperature rise) 100 ℃ (Only series : PCC-F126F(N6)) 

## **2-11. 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. 

When using this product for amusement purposes, contact our sales representative as it is necessary to fix the font in order to display the seal. 

## **2-12. 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. 

## ＜ Package markings ＞ 

Package markings include the product number, quantity, and country of origin. 

In principle, the country of origin should be indicated in English.
