TDK Co., Ltd. (President: Sakamoto Kenhiro) introduced the MHQ1005P series of laminated ceramic inductors in April 2012, offering performance comparable to traditional wound inductors while being more cost-effective. These components are widely used in high-frequency matching circuits for mobile devices like smartphones and tablets.

The MHQ1005P series achieves a Q value of 65 at 1 GHz with an inductance of 2.7 nH, matching the performance of similarly sized wound inductors. In the 2.4 GHz band—commonly used in Bluetooth and Wi-Fi applications—the Q value reaches 108, again matching the performance of wound inductors of the same size and inductance.

This impressive performance is made possible by TDK's advanced material technology and optimized internal design. The use of high-performance materials reduces losses, resulting in higher self-resonant frequencies. Additionally, structural improvements such as L-type terminals contribute to enhanced Q values.

Compared to traditional wound inductors, the MHQ1005P series offers lower component costs and supports efficient, low-loss circuit designs without compromising on performance. This makes it an ideal choice for modern high-frequency applications where space and efficiency are critical.

The MHQ1005P series includes inductors ranging from 1 nH to 10 nH in the E24 series, and 12–15 nH in the E12 series, providing flexibility for a wide range of applications.

Key Term:

· Q Value: The Q value (quality factor) of an inductor measures its efficiency under AC voltage at a specific frequency. It represents the ratio of inductive reactance to resistance. A higher Q value means less energy loss, better efficiency, and improved performance.

Main Applications:

· High-frequency circuits in mobile devices such as smartphones, tablets, and Bluetooth modules.

Main Features:

· Offers the same performance as wound inductors but at a lower cost, thanks to the lamination process. Ideal for high-frequency, high-performance, and cost-sensitive applications.
