SMD Inductors(Coils) For Power Line(Wound, Magnetic Shielded) VLF Series VLF3012A FEATURES • Miniature size Mount area: 2.6 × 2.8mm Low profile: 1.2mm max. height • Generic use for portable DC to DC converter line. • High magnetic shield construction should actualize high resolu- tion for EMC protection. • Available for automatic mounting in tape and real package. • The products contain no lead and also support lead-free soldering. • It is a product conforming to RoHS directive. APPLICATIONS Power souce inductor for mobile devices such as mobile phones, HDDs, and DSCs SHAPES AND DIMENSIONS RECOMMENDED PC BOARD PATTERN ELECTRICAL CHARACTERISTICS ∗1 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. ∗2 Inductance is at 1/2 Idc1 power distribution. The L vaule at 0A is higher than the guaranteed performance. • Operating temperature range: –40 to +105°C (Including self-temperature rise) TYPICAL ELECTRICAL CHARACTERISTICS INDUCTANCE vs. DC SUPERPOSITION CHARACTERISTICS VLF3012AT-1R5N1R2 VLF3012AT-2R2M1R0 Conformity to RoHS Directive 1.2max.
