RFC0810B-564KE RFC0810B-564 Inductor (560 uH)

RFC0810B-564KE is a high-performance through-hole power inductor manufactured by Coilcraft, a renowned leader in the design and production of magnetic components. This specific model, part of the RFC0810B series, is engineered to provide reliable energy storage and filtering in a wide array of power conversion applications. As a passive component, its primary function is to store energy in a magnetic field when current flows through it, and then release that energy, thereby smoothing current flow, filtering noise, and regulating voltage in electronic circuits. Its robust construction and precise inductance make it an ideal choice for demanding industrial and automotive environments.

Key Specifications

The RFC0810B-564KE boasts several critical specifications that define its performance and suitability for various applications: * Series: RFC0810B-564 – This indicates the specific product family, ensuring compatibility and consistent performance characteristics within the Coilcraft RFC0810B series. * DCR Max: 1.05 Ohm / DCR Typ: 895 mOhm – The DC Resistance (DCR) is a crucial parameter, representing the resistance of the inductor’s winding to direct current. A lower DCR minimizes power loss, leading to higher efficiency and reduced heat generation in power circuits. The typical value provides a benchmark for expected performance. * Shielded: No – This inductor is unshielded, meaning its magnetic field extends outside the component. While this can simplify manufacturing, designers must consider potential electromagnetic interference (EMI) with adjacent components, especially in densely packed circuits. * Inductance: 560 uH – This is the core characteristic, defining the inductor’s ability to store magnetic energy. A 560 microhenry inductance is suitable for various power filtering and energy storage applications, particularly in DC-DC converters and power supplies requiring moderate inductance values. * Core Material: Ferrite – Ferrite cores are widely used in power inductors due to their high magnetic permeability, which allows for higher inductance values in a compact size, and their ability to operate effectively at higher frequencies while minimizing core losses. * Mounting Type: Through Hole – This specifies that the component is designed for through-hole mounting, where leads pass through holes in a printed circuit board (PCB) and are soldered on the opposite side. This mounting method offers robust mechanical stability and is often preferred for power applications where physical stress or vibration might be a concern. * Component Type: Through Hole Power Inductor – This explicitly defines its function and mounting style, clarifying its role in power management circuits. * Size / Dimension: 9.5 x 9.5 x 11.5 mm – These dimensions provide the physical footprint and height of the component, critical for PCB layout and enclosure design, ensuring it fits within the allocated space. * AEC-Q200 Qualified: Yes – This is a significant qualification, indicating that the inductor meets the stringent reliability standards set by the Automotive Electronics Council for passive components. This makes it suitable for use in automotive applications where extreme temperatures, vibrations, and electrical stresses are common. * Current – Peak (Ipk): 0.75 A / Current – RMS (Irms): 0.75 A – These values represent the maximum peak and RMS (Root Mean Square) currents the inductor can safely handle without saturation or excessive heating. Operating within these limits is crucial for maintaining performance and component longevity. * Inductance Tolerance: ±10% – This specifies the permissible deviation from the nominal inductance value. A ±10% tolerance is standard for many power inductors, providing sufficient precision for most power conversion designs. * Operating Temperature: up to 125 °C – This wide operating temperature range highlights the inductor’s robustness, allowing it to function reliably in harsh thermal environments, a common requirement in industrial and automotive settings. * Current – Saturation (Isat): 1.06 A – The saturation current is the DC current at which the inductance drops by a specified percentage (typically 20% or 30%) from its initial value. It’s a critical parameter for power applications, as exceeding Isat can lead to a significant loss of inductance and degraded circuit performance.

Features and Benefits
