Selecting the appropriate molded inductor is essential for ensuring efficiency, reliability, and performance in modern electronic designs. Mentech offers two main series of molded inductors—MHA and MHC—each optimized for specific technical requirements. Understanding the differences between these series helps engineers make informed choices for power applications, automotive electronics, and high-current circuits.

MHA Series: Low DCR and High LRM
The MHA series of molded inductors is designed with low direct current resistance (DCR) and high inductance-to-resistance ratio (LRM). These characteristics make the MHA series well-suited for applications where efficiency and minimal power loss are critical. Common uses include voltage regulation modules, DC-DC converters, and power supply circuits where low energy loss and stable magnetic performance are priorities. The MHA series offers an inductance range from 0.047µH to 150µH, supports operating temperatures up to 155°C, and provides reliable performance under standard current loads.
MHC Series: High Current Capability
In contrast, the MHC series is designed to handle higher currents efficiently. With robust construction and thermal management, these molded inductors maintain stable inductance even under transient peaks, making them ideal for high-current power supplies, automotive electronics, and industrial applications. The MHC series ensures reliable operation in demanding environments, supporting transient currents and minimizing self-induced electromagnetic interference (EMI).
Choosing Between MHA and MHC
When selecting a molded inductor, engineers should consider both current requirements and efficiency goals. The MHA series is ideal for applications that prioritize low DCR and reduced power loss, whereas the MHC series excels in high-current environments requiring stable performance under load. Both series share benefits such as compact size, one-piece molded shielding, and improved thermal performance, ensuring reliability across a wide range of applications.
Conclusion
For design engineers evaluating component options, Mentech molded inductors provide versatile solutions tailored to different technical needs. Choosing between the MHA and MHC series depends on whether the priority is high efficiency with low DCR or superior current handling. By understanding the specific characteristics of each series, engineers can optimize performance and reliability in power supply circuits, automotive systems, and other electronics applications.
