# Inductors (Coils/Cores): A Comprehensive Guide to Series, Applications, and Design Resources
 
**Key Product Series and Features:**
 
The page details a range of inductor series, categorized by core material and key features. Each series is optimized for specific applications, including common mode filtering, normal mode filtering, PFC (Power Factor Correction), voltage boosting, and output smoothing. Here's a breakdown:
 
*   **Nanocrystalline Cores (FL, FL-V):**  Emphasize high permeability for common mode noise filtering and improved low-frequency performance. The FL-V series offers particularly high permeability for common mode applications, while the standard FL series is a reliable choice for common mode noise filtering.
 
*   **Alloy-Based Dust Cores (DM):** Optimized for downsizing and high-efficiency PFC voltage boosting coils.
 
*   **Amorphous Cores (KA, SM, AM, AW, CM, CMJ, BM, TM):** Offer a variety of features tailored to different needs.
 
    *   **KA:** Amorphous without gap, utilizing a 1-Turn structure (Low DCR) and Surface Mount Structure.
    *   **SM:** Amorphous without gap, featuring a feedthrough core with a single-turn lead wire for remarkably small D.C. resistance.
    *   **AM:** Amorphous with gap, demonstrating more excellent D.C. bias characteristics in large-current applications.
    *   **AW:** Amorphous with gap, offering downsizing compared to the AM Series for large-current applications.
    *   **CM:** Amorphous with gap, presented as a standard type in a smaller size compared to ferrite choke coils.
    *   **CMJ:** Amorphous with gap, achieving miniaturization compared to the CM Series coil by about 30%.
    *   **BM:** Amorphous without gap, offering downsizing compared to the TM Series.
    *   **TM:** Amorphous without gap, designed for downsizing and low leakage magnetic flux.
