TDK Corporation has expanded its portfolio of multilayer power inductors
The current lineup covers inductance values from 160 nH to 560 nH. Thanks to their high rated currents ranging from 550 mA to 750 mA, they ensure operational stability even when handling the AC signal currents in the range of 100 mA to 300 mA that are encountered when the communication circuit is active. The compact IEC 1608 package (EIA 0603) of the MLJ1608 series has a footprint of 1.6 mm x 0.8 mm and a low-profile insertion height of 0.8 mm. Mass production of the MLJ1608 series began in April of this year.
The MLJ1608 series relies on a newly developed low-loss ferrite material from TDK which makes it possible to realize lower loss values with AC signals than achieved with similar sized wound coils. The superposition performance of the ferrite material has also been improved, resulting in characteristics that are on a par with those of conventional wound coils at the 300 mA peak current levels flowing in the NFC circuit.
An additional MLJ1005 series in an IEC 1005 (EIA 0402) package is currently under development and will add products suitable for low power NFC modules and applications requiring very small dimensions.
