TDK launches industry’s smallest 0201-size high-frequency inductors for RF modules

May 30, 2025 — TDK Corporation has initiated mass production of its MUQ0201022HA series, marking the launch of the world’s smallest high-frequency inductors in the 0201 size format (0.25 x 0.125 x 0.2 mm). Designed for GHz-band applications in smartphones and wearable devices, these components offer advanced electrical performance while significantly reducing footprint.

By leveraging proprietary patterning and sintering techniques, TDK has achieved RF characteristics on par with, or exceeding, its existing MHQ0402PSA series, despite the MUQ series occupying roughly half the mounting area. The new lineup covers an inductance range from 0.6 nH to 3.6 nH, catering to the growing demand for compact yet high-performance RF components in next-generation mobile platforms.

As system designers face increasing pressure to integrate more functionality in ever-smaller spaces, TDK’s 0201-sized inductors provide a practical solution for impedance matching in high-frequency front-end modules and wearable applications.

TDK aims to expand the series further to support a wider array of high-frequency design needs across the semiconductor and communications sectors.
