The **CTX150-1-52LP-R** is a high-performance power inductor, specifically a **dual-winding toroidal inductor** part of the Octa-Pac® PLUS series manufactured by Eaton (formerly Cooper Bussmann/Coiltronics). --- ## 1. Component Specifications The following table summarizes the key electrical and physical characteristics of the device: | Property | Value/Description | | :--- | :--- | | **Inductance** | 150 µH (Nominal) | | **Tolerance** | ±20% | | **Current Rating (Irms)** | ~0.70 Amperes (approximate) | | **Saturation Current (Isat)** | ~0.45 Amperes (approximate) | | **DCR (Direct Current Resistance)** | ~0.650 Ohms (per winding) | | **Winding Configuration** | Dual Winding (can be used in Series or Parallel) | | **Core Material** | Iron Powder (Material -52) | | **Package Type** | Surface Mount (Low Profile "LP") | --- ## 2. Key Features and Construction ### Dual Winding Versatility Because this component contains two separate windings on a single core, it offers significant flexibility for circuit designers: * **Series Connection:** Increases total inductance (4x the single winding inductance). * **Parallel Connection:** Increases current handling capability while keeping the inductance value the same as a single winding. * **1:1 Transformer:** Can be used as a common-mode choke or a basic isolation transformer. ### Material Properties (-52) The "52" in the part number refers to the **Iron Powder material**. * **Low Core Loss:** It is optimized for high-frequency applications. * **High Saturation:** Unlike ferrite cores that "hard-saturate" (dropping inductance suddenly), iron powder provides a "soft-saturation" curve, which is safer for power supply stability. ### Form Factor (LP-R) * **Low Profile:** The "LP" designation indicates a reduced height, making it ideal for compact consumer electronics or thin PCB stacks. * **RoHS Compliant:** The "R" suffix indicates the part is lead-free and meets environmental standards. --- ## 3. Typical Applications The CTX150-1-52LP-R is commonly found in the following circuits: 1. **DC-DC Converters:** Used as the main energy storage inductor in Buck, Boost, or SEPIC topologies. 2. **EMI Filtering:** Functioning as a common-mode choke to filter out high-frequency noise. 3. **Battery Powered Devices:** Due to its efficient size-to-inductance ratio. 4. **Signal Isolation:** Basic coupling applications where 1:1 voltage ratio is required. ---
