HDDs, and DSCs
SHAPES AND DIMENSIONS
RECOMMENDED PC BOARD PATTERN
ELECTRICAL CHARACTERISTICS
Rated current: Value obtained when current flows and the temperature has risen to 40°C or when DC current flows and the nominal value of inductance
has fallen by 30%, whichever is smaller.
Operating temperature range: –40 to +105°C (Including self-temperature rise)
