Coilcraft has introduced two low profile wirewound chip inductor families.

The 0402CT chip inductor Series features a ceramic core and has a maximum height of just 0.45 mm, 30 percent lower than previous products. Offered in 23 inductance values from 1.2 to 56 nH (with, 5 percent, 3 percent or 2 precent tolerance), the 0402CT provides a Q Factor of up to 84 at 2.4 GHz. It also offers self-resonant frequencies as high as 27.5 GHz and current ratings up to 2.3 Amps (Irms).

The ferrite-core 0402FL Series has a maximum height of 0.55 mm and is offered in 16 inductance values from 20 to 560 nH. It is ideal for use as a one-pole filter or RF choke in cellular bands, and can be used in both mobile and infrastructure equipment. The 0402FL’s ferrite construction provides high current handling — up to 1.3 Amps (Irms) — with extremely low DCR.

Both the 0402CT and 0402FL feature RoHS compliant, with matte tin over nickel over silver-platinum-glass frit terminations and both can withstand a maximum reflow temperature of 260°C.

Technical specifications and free evaluation samples of the 0402CT and 0402FL Series are available at  www.coilcraft.com. Parts are available from stock and can be ordered on-line
