The **CTX50-10-52LP-R** is a high-performance power inductor, specifically a toroidal inductor manufactured by **Eaton (formerly Cooper Bussmann/Coiltronics)**. It belongs to the **Octa-Pac® Plus** series, known for its low profile and high power density. --- ### ## Technical Specifications Below are the key electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Inductance** | 50 µH (Nominal) | | **Current Rating (Irms)** | ~10 Amps (approximate based on series) | | **Core Material** | Powder Iron (Type -52) | | **Mounting Type** | Surface Mount (SMD) | | **Configuration** | Dual Winding (can be series or parallel) | | **Operating Temp** | -40°C to +125°C | | **Shielding** | Non-shielded (Toroidal geometry naturally contains flux) | --- ### ## Key Features & Construction 1. **Dual Winding Design:** The device consists of two separate windings on a single core. This allows for versatility: * **Series connection:** Increases total inductance. * **Parallel connection:** Increases current handling capability. * **1:1 Transformer:** Can be used as a flyback transformer or a common mode choke. 2. **Core Material (-52):** The suffix `-52` refers to the specific iron powder material. It is optimized for frequencies up to **500 kHz**. It offers a good balance between low core loss and high permeability, making it ideal for energy storage. 3. **Low Profile (LP):** The "LP" designation indicates a low-profile package, designed for space-constrained PCB applications where vertical height is limited. --- ### ## Common Applications This inductor is typically found in power management circuits, including: * **DC-DC Converters:** Used in buck, boost, and forward converters. * **Switching Regulators:** Acting as an energy storage element. * **EMI Filtering:** Utilized as a common mode or differential mode choke to reduce electronic noise. * **Renewable Energy:** Integrated into solar inverters and battery management systems. --- ### ## Identification Code Breakdown * **CTX:** Coiltronics/Eaton Series designation. * **50:** Inductance value (50 µH). * **10:** Size/Power rating code. * **52:** Core material type (Iron Powder). * **LP:** Low Profile package. * **R:** RoHS compliant (Lead-free).
