New High Current Air Core Inductors Offer Q Factors Up To 230 at 400 MHz

Cary, IL, USA - Coilcraft’s new VS Series air core inductors combine current ratings of up to 57.0 Amps and excellent Q factors, making them ideal for high current IF/RF applications.  Other applications include high power filtering, high frequency VRMs where magnetic material must be avoided (e.g., in MRI machines), and as high current IF chokes.

VS SeriesThe VS Series is offered in three sizes/configurations. The 1010VS measures 10.0 X 10.0 mm, with a maximum height of 6.10 mm. It is available with five inductance values between 23.5 and 146 nH, current ratings up to 26.0 Amps, and Q factors as high as 150.

The 1212VS measures 12.0 X 11.5 mm with a maximum height of 11.3 mm. It’s offered with five inductance values ranging from 22.2 to 117 nH, current ratings up to 57.0 Amps and Q factors as high as 200.

The 2014VS measures 19.56 X 13.6 mm with a maximum height of 11.4 mm. It’s available with six inductance values between 33 and 257 nH, current ratings up to 43.0 Amps and Q factors as high as 230.

All VS Series air core inductors feature RoHS compliant tin-silver over copper terminations and offer a maximum reflow temperature of 260°C. COTS Plus tin-lead terminations are also available.

As with all Coilcraft parts, free evaluation samples and complete technical specifications for the VS Series are available online at Parts are available from stock and can be ordered on-line at or by calling a local Coilcraft sales office.

Coilcraft also offers its C456 Designer’s Kit which contains five samples of each inductance value offered for all three series (16 values in total).
