0402 chip inductor duo have low profiles

Two of low-profile, wirewound chip inductors, the 0402CT and the 0402FL series, have been announced by Coilcraft.

The 0402CT series features a ceramic core and has a maximum height of just 0.45mm. Coilcraft says its profile is 30 per cent lower than competitive products. It is offered in 23 inductance values from 1.2 to 56 nH (with tolerances of two, three or five per cent). The 0402CT provides excellent Q Factor performance – up to 84 at 2.4GHz, adds Coilcraft. It also offers self-resonant frequencies as high as 27.5GHz and current ratings up to 2.3A (Irms).

The ferrite-core 0402FL series has a maximum height of 0.55mm and is offered in 16 inductance values from 20 to 560 nH. It is intended 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, says Coilcraft, up to 1.3A (Irms) and with extremely low DCR.

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

Both inductors are supplied with complete technical specifications and free evaluation samples. Parts are available from stock.

Coilcraft is headquartered in Cary, outside Chicago, Illinois. It supplies magnetic components including high performance RF chip inductors, power magnetics and filters. It also designs and builds custom magnetics to fit a customer’s exact electrical requirements.

The company also offers engineers and buyers engineering support.
