The part number **2322-R** typically refers to a **High-Current Toroidal Inductor** manufactured by J.W. Miller (now part of Bourns Inc.). These components are designed for applications requiring high saturation currents and efficient power management. --- ### 1. Key Technical Specifications The "2322" series follows specific electrical parameters. Below is a summary of the general specifications for the **2322-R** model: | Parameter | Typical Value | | :--- | :--- | | **Inductance** | 10.0 µH | | **Tolerance** | ±15% | | **Current Rating (DC)** | 12.8 Amperes | | **DC Resistance (Max)** | 0.008 Ohms | | **Mounting Type** | Through-Hole | | **Core Material** | Iron Powder | --- ### 2. Physical Construction The "R" suffix in the part number usually denotes **RoHS compliance** (Lead-free). * **Toroidal Core:** The circular (donut) shape is highly efficient because it contains the magnetic flux within the core, reducing Electromagnetic Interference (EMI) with surrounding components. * **Winding:** Thick copper wire is wound around the iron powder core to handle high current without overheating. * **Lead Finish:** Pre-tinned leads for easy soldering onto Printed Circuit Boards (PCBs). --- ### 3. Common Applications These inductors are found in circuits where power stability and noise filtering are critical: 1. **Switching Power Supplies:** Used as storage elements in DC-DC converters (Buck/Boost). 2. **EMI/RFI Filtering:** Acting as a choke to block high-frequency noise in power lines. 3. **Output Chokes:** Smoothing the output current in high-current power stages. 4. **Signal Conditioning:** Protecting sensitive electronics from voltage spikes. --- ### 4.
