TDK Corporation announced the new MHQ0402PSA series of multilayer inductors in case size IEC 0402. Measuring in with reduced dimensions of just 0.4 mm x 0.2 mm x 0.2 mm, the new inductors feature a Q factor of 21 at 1 GHz. Mass production began in January 2016.

The high Q of 21 of the MHQ0402PSA series at an inductance of 0.3 nH, represents an improvement of over 30% compared to TDK's existing MLG0402Q series. The achievement of the high Q factor in an extremely compact package was made possible by TDK's proprietary dielectric materials technology, combined with an optimized coil pattern and an internal electrode cross-section design with a high aspect ratio. Main applications were: Smartphones, tablets, Bluetooth and WLAN devices; RF circuits and modules for mobile communication devices, including PAs, VCOs, and front-end modules.

Main features and benefits were High Q factor contributes to reduced losses in RF circuits.
