Tolerance of Inductance
CDRH12D58/A 10µH – 390µH ± 20% (M)
CDRH12D78/A 10µH – 390µH ± 20% (M)
CDRH127C/A
Other
*A The rated DC current Indicates the DC current when the inductance decreases to maximum 65% of nominal value or
10µH – 470µH ± 20% (M)
ꢀ
DC current when the temperature of coil is increased to 30 °c. The smaller one is defined as DC rated current.

NOTE
Please note that when using the product for automotive while applying current with audio-frequency (AF) signals may result in audible noises due to magnetostriction.
Also, in order to avoid an audible noise problem, operating with Non-AF signals would be recommended. The noise may amplify depending on the coil mount area on the PCB.
