SMD Inductors(Coils)
For Power Line(Wound, Magnetic Shielded)
VLF Series VLF3010A
FEATURES
• These are compact inductors for power line measuring at L2.6×
W2.8mm and 1mm in height, considerably smaller compared to
inductors with comparable characteristics.
• They feature low coil resistance, making them suitable for large
currents (e.g. 0.7A at 0.24Ω).
• They offer an excellent shielding effect.
• The products do not contain lead and support lead-free solder-
ing.
• This product does not contain regulated substances that are
slated to be included in RoHS.
APPLICATIONS
For mobile phones, hard disk drives and DSCs.

ELECTRICAL CHARACTERISTICS
∗
Rated current:The rated current is the smaller of the values given based on the rate of inductance change (30% decrease from the initial value) or the
temperature rise (temperature rise of 40°C caused by the heat generated by the product itself).
• Operating temperature range: –40 to +105°C (Including self-temperature rise)
