    Product Description

    Air-core Coil

    FEATURES:

    The air coil inductor SMAR Series features air core construction, delivering minimal core losses and superior performance in demanding circuits. With an excellent quality factor (Q) up to 145, it ensures efficient energy storage and low distortion. High current ratings from 1.6A to 4.4A make it a robust Power Inductor for energy-intensive systems. It offers a broad inductance range of 1.65 nH to 538 nH, with tight tolerances of ±2%, ±5%, or ±10%, ensuring precision in diverse setups. The high self-resonant frequency (SRF) enhances stability in high-frequency operations. Compact dimensions support reliable pick-and-place assembly, while an operating temperature range of -40°C to +125°C guarantees reliability in harsh environments. This Air Core Inductor is RoHS-compliant, with a reflow profile peaking at 255–260°C for easy integration.

    APPLICATIONS:

    Ideal for RF Inductor roles in wireless communication and RF circuits, this series excels in broadband I/O filtering and EMC Filter implementations for noise suppression. It is perfect for impedance matching/tuning in Transformers and Sensor-based systems, ensuring signal integrity. As a Power Inductor, it is essential in Power Converter designs for efficient voltage regulation and energy management. Additionally, it serves in decoupling/bypassing applications for power supplies and EMC Filter enhancements. For Sensor interfaces and Transformers, it provides stable performance, while in RF Inductor setups, it maximizes frequency response. Integrate it into Power Converter units for optimized industrial and automotive solutions.

    KEY SPECIFICATIONS:

    Inductance values span from 1.65 nH (e.g., SMAR1422-1N65) to 538 nH (e.g., SMAR6310-538N), tested at frequencies like 50 MHz or 800 MHz depending on the model. Typical Q factor exceeds 100, with SRF ranging from 10 GHz to 0.49 GHz. Maximum DC resistance (DCR) is as low as 1.1 mΩ for high-efficiency designs, while rated current (Irms) supports up to 4.4A, underscoring its role as a Power Inductor. Storage temperature ranges from -40°C to +85°C. Use this RF Inductor in EMC Filter configurations or Sensor circuits for reliable operation. For Power Converter systems, it handles high currents with minimal loss. As an Air Core Inductor, it is versatile across Transformers and EMC Filter applications.
