Multilayer power inductors are made for high switching frequencies.

TDK has announced the availability of the company's first multilayer power inductors for high switching frequencies. The MLP2520, MLP3225 and MLP3216 feature excellent DC/AC resistance, which results in improved efficiency and standby time, both of which are paramount for battery driven devices. Thanks to their multilayer design, the inductors have a low profile of approximately 1mm, making them ideal for handheld applications.

TDK has designed these products for use as DC/DC convertors in small devices.

The company recognised the need for engineers to reduce the size of their devices, so it turned to its extensive experience in multilayer technology to develop these lower profile power inductors.

The design of the MLP2520, MLP3225, and MLP3216 power inductors make them well suited for small devices such as mobile phones, PDAs, and portable MP3 players.

Furthermore, the ferrite materials used to construct these power inductors are bespoke for this product type.

The inductors also boast excellent mounting strength thanks to SMD chip making.

The components are RoHS compliant and completely lead-free.

The MLP3225, MLP3216 and the MLP2520 are available in three standard heights, with case sizes of 3.2 x 2.5, 3.2 x 1.6 and 2.5 x 2.0mm, respectively.

The MLP2520 has a height of 1mm and resistance of 0.06-0.11ohm, and current ratings of 1100-1500mA.

The MLP3216 has a height of 0.8mm and resistance of 0.12-0.13ohm, and current rating of 1000mA.

The MLP3225 has a height of 1-1.4mm and resistance of 0.13-0.16ohm, and current rating of 900-1100mA.
