May 22, 2025 /SemiMedia/ — TDK Corporation has expanded its MUQ0201022HA series of high-frequency inductors, introducing the industry’s smallest 0201 size (0.25 x 0.125 x 0.2 mm) components. These inductors maintain equivalent electrical performance to the existing larger 0402 size (0.4 x 0.2 mm) MHQ0402PSA series, with inductance values ranging from 0.6 nH to 3.6 nH. Mass production began in May 2025.

Driven by the demand for smaller and more advanced mobile devices such as smartphones and wearables, TDK applied proprietary patterning and sintering technologies to reduce the mounting area by roughly half without compromising high-frequency performance. This enables enhanced miniaturization and performance in semiconductor high-frequency front-end modules. TDK plans to further expand its lineup to meet evolving customer requirements in high-frequency inductors.

Key applications include impedance matching in mobile and wearable device high-frequency front-end modules. The product offers superior frequency characteristics in a smaller footprint, supporting advanced semiconductor device design and integration.
