Based on the part number provided, **92-6-R** typically refers to a **High-Current Toroidal Inductor** (specifically from the 92 Series produced by manufacturers like *Gowanda Electronics* or *API Delevan*). These components are designed for high-frequency power applications where stability and high current handling are required. --- ### 1. Technical Specifications The "92-6-R" follows a specific naming convention. The "R" usually indicates **RoHS compliance** (Lead-Free). | Feature | Specification (Typical) | | :--- | :--- | | **Inductance** | 2.5 µH | | **Current Rating (DC)** | ~25.0 Amperes | | **DC Resistance (Max)** | 0.003 Ohms (3 mΩ) | | **Core Material** | Powdered Iron / Ferrite | | **Configuration** | Toroidal (Donut-shaped) | | **Mounting Type** | Through-Hole (Vertical or Horizontal) | --- ### 2. Physical Construction The part is built using the following elements: * **Toroidal Core:** The ring shape helps contain the magnetic flux within the core, significantly reducing Electromagnetic Interference (EMI) compared to traditional bobbin inductors. * **Heavy Gauge Wire:** Because it handles high current (up to 25A), the copper winding is thick to prevent overheating. * **Lead Finish:** Sn/Ag/Cu or pure Matte Tin (RoHS compliant). --- ### 3. Key Applications These inductors are commonly found in power management circuits: * **Switching Power Supplies:** Used as an output filter to smooth out current ripples. * **DC-DC Converters:** Essential for energy storage during the switching cycle. * **EMI/RFI Filtering:** Used in industrial equipment to block high-frequency noise from entering or leaving the system. * **Audio Equipment:** Sometimes used in high-power crossovers or power stages. --- ### 4. Advantages 1. **Low EMI:** The toroidal geometry ensures minimal magnetic leakage. 2. **High Saturation:** Powdered iron cores handle high peak currents without the inductance "crashing" or saturating quickly. 3. **Efficiency:** Very low DC resistance (DCR) minimizes power loss as heat.
