Delta Electronics SMT Power Inductor SIQ1048 Series Manuals

1. Tolerance of inductance: 1.0~1.8uH 30% , 2.8~470uH 20%. 2. Irated is the DC current which cause the inductance drop 20% typical of its nominal inductance without current and the surface temperature of the part increase less than 45 oC. o 3. Operating temperature: -20 C to 105 (including self-temperature rise). SMT Power Inductor SIQ1048 Type RoHS compliant. Low profile (4.8mm max. hegiht ), high current(13.6A) SMD type. Magnetically shielded, suitable for hight density mounting. High energy storage and low DCR. Provided with embossed carrier tape packing. Ideal for power source circuits, DC-DC converter,DC-AC inverters inductor applications. In addition to the standard versions shown here, customized inductors are available to meet your exact requirements. Features Electrical Characteristics: DELTA ELECTRONICS, INC.
