Coilcraft, represented by Tri Components in Australia, has introduced SQ series of air core inductors. At operating frequencies, these new SQ air core inductors have Q factors in the range of 250 – 350.
And even with their miniature size, they can handle currents up to 4.4A. the SQ air core inductors are roughly the size of a conventional 0805 chip inductor. The SQ air core inductors are available with 15 inductance values from 6 to 27.3nH, all with 5% inductance tolerance.
The small footprint of these new SQ air core inductors comes from their close-wound construction. The square shape reduces the height to as low as 1.5mm while providing a surface ideal for automated handling.
The features of the SQ air core inductors are:
- Inductance values from 6 to 27.3nH, ±5% tolerance
- Maximum Q factors up to 130
- Current ratings from 2.7 to 4.4A
- Very low DCR ratings from 6 to 10mΩ
- Extremely low profile - 1.5 to 2.03mm
- Flat top and bottom for easy handling and mounting
- RoHS compliant and 260° compatible
