The **CTX150-1P-R** is a high-performance power inductor, part of the **OCTA-PAC® PLUS** series manufactured by **Eaton (formerly Cooper Bussmann/Coiltronics)**. This component is specifically designed for high-current applications and power conversion circuits. ### 1. Technical Specifications The following table summarizes the key electrical characteristics of the CTX150-1P-R: | Parameter | Specification | | :--- | :--- | | **Inductance** | 15.0 µH (nominal) | | **Current Rating (Irms)** | 6.57 Amperes | | **Saturation Current (Isat)** | 8.01 Amperes | | **DC Resistance (DCR)** | 0.0195 Ohms (Max) | | **Operating Temperature** | -40°C to +125°C | | **Package/Case** | Surface Mount (SMD) | | **Core Material** | Powdered Iron (High stability) | --- ### 2. Key Features and Construction The "OCTA-PAC PLUS" designation refers to the specific physical and magnetic architecture of the part: * **Toroidal Geometry:** It utilizes a toroidal (ring-shaped) core which is excellent for containing magnetic flux, resulting in low Electromagnetic Interference (EMI). * **High Power Density:** Designed to handle significant current in a relatively small footprint. * **E-I Core Alternative:** Unlike standard E-cores, the toroidal design provides a more uniform magnetic path. * **RoHS Compliant:** The "-R" suffix indicates that the part is lead-free and meets RoHS environmental standards. --- ### 3. Common Applications The CTX150-1P-R is versatile and typically found in the following electronic circuits: 1. **DC-DC Converters:** Used as a storage inductor in Buck (Step-down), Boost (Step-up), and SEPIC topologies. 2. **Voltage Regulator Modules (VRM):** Essential for stabilizing power delivery to CPUs and high-end processors. 3. **Noise Filtering:** Acts as an effective EMI filter for power lines in telecommunications and industrial equipment. 4. **Battery Powered Systems:** High efficiency and low DCR make it suitable for extending battery life in portable electronics. --- ### 4. Footprint and Soldering The component is designed for **Surface Mount Technology (SMT)**. It features secure mounting pads that provide high mechanical stability against vibration and thermal cycling. ```text Physical Dimensions (Approximate): Length: 15.0 mm Width: 12.7 mm Height: 6.35 mm ```
