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 enabling mass production. These components are widely used in high-frequency matching circuits for mobile devices such as smartphones and mobile phones.

The MHQ1005P series delivers a Q value of 65 at 1 GHz with an inductance of 2.7 nH, matching the performance of wound inductors of the same size and inductance. In the 2.4 GHz band, where the standard inductance is 2.7 nH, the Q value reaches 108, again equivalent to a wound inductor of similar specifications.

This impressive Q performance is achieved through TDK's advanced material technology and optimized internal design. By using high-performance materials, the series reduces losses and increases self-resonant frequencies. Additionally, structural improvements such as L-type terminals contribute to enhanced Q characteristics.

Thanks to these innovations, the MHQ1005P series offers lower component costs and more efficient, low-loss circuit designs compared to traditional wound inductors with similar Q values. This makes it a cost-effective solution without compromising on performance.

The MHQ1005P series includes E24 series inductors ranging from 1 nH to 10 nH, as well as E12 series inductors between 12 nH and 15 nH, providing a wide range of options for various applications.

Key Terms:

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

Applications:

· High-frequency circuits in mobile devices like smartphones, mobile phones, and Bluetooth modules.

Features:

· Offers the same performance as wound inductors but at a lower cost due to the lamination process. Ideal for high-frequency, high-performance, and cost-effective circuit designs.
