TDK Launches AEC-Q200 Qualified Inductors for High Frequency Applications

TDK Launches AEC-Q200 Qualified Inductors for High Frequency Applications

TDK Corporation, an electronic components manufacturer leading the world in magnetic technology, has announced the introduction of its new MHQ1005075HA series of inductors for automotive high-frequency circuits. This product uses the same materials and construction methods as the conventional product while applying TDK's proprietary design expertise to the internal structure from the perspective of fail-safe design. The series is 1005 size (1.0 × 0.5 × 0.7 mm - L x W x H), and the inductance ranges from 1.0 nH to 56 nH. Mass production of the product series began in February 2024.

Inductors for high-frequency circuits for automotive or infrastructure use must meet higher standards for safety and reliability, designed based on AEC-Q200. The product leverages TDK's one-of-a-kind design expertise in the design of the internal structure to realize high-frequency properties equal to or superior to conventional products. For example, the inductor’s internal structure is designed to reduce the chances of an open failure due to cracks in the mount points of the component. Combined with automotive circuit board manufacturing guidelines, the TDK MHQ1005075HA inductor can deliver a sizable increase in reliability in an automotive environment. TDK will further expand its line to meet the evolving needs of customers.


  • Inductors for high-frequency circuits: Inductors for high-frequency band (GHz band) are used in inductor products
  • AEC-Q200: Automotive Electronics Council. The standards for passive components for automobiles

Key features 

  • The high-frequency properties equal or superior to the conventional products are realized using an original internal structure developed by TDK
  • High reliability and AEC-Q200-ready because its structure prevents breaking problems caused by circuit board bending stress (automotive grade)
  • The multilayer method allows for a lineup with fine increments of inductance
  • Offers a wide operating temperature range of -55 to +1250 C.

Key applications

  • High-frequency circuits for automotive equipment (transmitter-receiver circuitry for communications inside and outside the car, such as telematics and V2X)
  • High-frequency transmitter-receiver circuitry for radio communications of smartphones, tablets, base stations and other devices (used as a component for impedance matching or filter circuits)
