The **CTX110600-R** is a high-performance, surface-mount power inductor belonging to the **OCTA-PAC® PLUS** series, manufactured by Eaton (formerly Cooper Bussmann/Coiltronics). These components are unique because they feature **dual windings**, allowing them to be configured in multiple ways. --- ### 1. Technical Specifications Below are the primary electrical and physical characteristics of the CTX110600-R: | Feature | Specification | | :--- | :--- | | **Inductance (Parallel)** | 600.2 µH | | **Inductance (Series)** | 2400.8 µH | | **Current Rating (Irms)** | 0.44 Amps (Parallel) | | **DC Resistance (DCR)** | 1.832 Ohms (Max per winding) | | **Operating Temperature** | -40°C to +125°C | | **Package Size** | OCTA-PAC® PLUS Size 1 | | **Termination** | RoHS Compliant (Matte Tin over Copper) | --- ### 2. Key Internal Components & Materials The reliability of the CTX110600-R comes from its specific material composition: * **Core Material:** Powered Iron. This provides high saturation flux density and is ideal for energy storage applications. * **Dual Windings:** It consists of two identical copper coils wound on a single core. This allows the user to connect them in series or parallel to double the inductance or the current capacity. * **Secure Packaging:** The "PLUS" designation indicates an enhanced construction that uses high-temperature materials and adhesives to withstand lead-free reflow soldering temperatures. --- ### 3. Application Use Cases Because of its dual-winding nature, this part is highly versatile: 1. **DC-DC Converters:** Used in Buck, Boost, and SEPIC topologies. 2. **Transformers:** Can function as a 1:1 isolation transformer or a flyback transformer. 3. **Common Mode Chokes:** Used for EMI filtering in power lines to suppress noise. 4. **Energy Storage:** High inductance makes it suitable for smoothing ripples in power supplies. --- ### 4. Comparison: Series vs. Parallel Connection The user must decide how to bridge the pins on the PCB to achieve the desired performance: * **Series Connection:** High inductance, lower current rating. Connect Pin 2 to Pin 3; input on Pin 1, output on Pin 4. * **Parallel Connection:** Lower inductance, higher current rating. Connect Pin 1 to 2 and Pin 3 to 4.
