5 x 6.4 mm SMD inductor, similar to VK200, usable up to 30-50MHz, 3A continuous current.
TDK, a brand leader in ferrites field, manufactures this SMD product with 8 metallized in series holes, very similar to the traditional VK200.
This inductor has a lower inductance value (about 1 µH at 100 MHz) and it can be used at frequencies over 30-50 MHz with a continuous current of 30A or a peak current of 5A in a very reduced space of only 5 x 6.4 mm. Here you can find the diagrams of the measures obtained with network analyzer and impedance-meter up to 500 MHz. This product, among TDK selection, represents the type with the highest impedance and highest current.
