Inductance is measured at 1.0 MHz.
Rated current defines actual value of DC current, when temperature rise of coil becomes 40 K. (Method A)
Rated current defines actual value of DC current, when temperature rise of coil becomes 40 K. (Method B)
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.
