Standard Parts
Standard Packing Quantity (Minimum Quantity/Packing Unit)
(✽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 defines actual value of DC current, when temperature rise of coil becomes 40 K. (Method B)
(✽4) Reference only
(✽5) 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.
