The **CTX150-2-52LP-R** is a specific electronic component belonging to the **OCTA-PAC® PLUS** series, manufactured by Eaton (formerly Cooper Bussmann/Coiltronics). This part is a high-power, surface-mount toroidal inductor/transformer. --- ## 1. Technical Specifications The part number encodes specific data about its construction and performance. | Parameter | Specification | | :--- | :--- | | **Inductance (Parallel)** | 14.8 µH | | **Inductance (Series)** | 59.3 µH | | **Current Rating (Isat)** | ~2.65 A (Parallel) | | **DC Resistance (DCR)** | ~0.046 Ω (Parallel) | | **Core Material** | Powered Iron (Material -52) | | **Configuration** | Dual Winding (Two identical coils) | | **Mounting Type** | Surface Mount (SMD) | | **Operating Temp** | -40°C to +125°C | --- ## 2. Key Features and Construction ### Dual Winding Versatility The most significant feature of this part is the **two separate windings** on a single core. This allows the component to be used in three distinct ways: 1. **Series Inductor:** Connecting the coils in series quadruples the inductance. 2. **Parallel Inductor:** Connecting the coils in parallel maintains the base inductance but doubles the current capacity. 3. **1:1 Transformer:** Using one winding as a primary and the other as a secondary for isolation or voltage transformation. ### Material -52 Core The "-52" in the part number refers to the core material (blue/green iron powder). This material is optimized for: * High frequency applications (up to 500kHz). * Lower core losses compared to standard iron powder. * Stable performance under high-temperature conditions. --- ## 3. Applications Due to its rugged design and dual-winding flexibility, it is commonly found in: * **DC-DC Converters:** Used in Buck, Boost, and SEPIC topologies. * **EMI Filtering:** Acting as a common-mode or differential-mode choke. * **Power Supplies:** Specifically in high-density power modules for industrial or telecommunications equipment. * **Isolation:** Providing signal or power isolation in low-wattage circuits. --- ## 4.
