The **CTX10-2-52LP-R** is a specific electronic component belonging to the **OCTA-PAC® PLUS** series, manufactured by **Eaton (formerly Cooper Bussmann/Coiltronics)**. It is a surface-mount (SMD) power inductor that features two identical windings. --- ### 1. Technical Specifications The following table summarizes the core electrical and physical characteristics of this part: | Parameter | Specification | | :--- | :--- | | **Inductance (Parallel)** | 10.3 µH | | **Inductance (Series)** | 41.2 µH | | **Rated Current (Irms)** | 2.50 Amperes | | **DC Resistance (DCR)** | ~0.046 Ω (Parallel) | | **Core Material** | Powered Iron (Material -52) | | **Operating Temperature** | -40°C to +125°C | | **Mounting Type** | Surface Mount (SMD) | | **Dimensions** | ~11.4mm x 11.4mm x 6.0mm | --- ### 2. Key Features and Construction * **Dual Winding Design:** It consists of two separate coils wound on a single toroid core. These can be connected in **series** (to increase inductance) or **parallel** (to increase current capacity). * **Material -52 Core:** The "-52" suffix refers to the iron powder core material. This material is known for high frequency stability and low core losses in power conversion applications. * **Low Profile (LP):** The "LP" in the part number indicates a low-profile design, making it suitable for compact PCB layouts where height is restricted. * **RoHS Compliant:** The "-R" suffix confirms that the part meets lead-free and environmental safety standards. --- ### 3. Common Applications Due to its versatile dual-winding configuration, the CTX10-2-52LP-R is commonly used in: 1. **DC-DC Converters:** Acts as a buck, boost, or SEPIC inductor. 2. **1:1 Transformers:** Can be used as a basic isolation or flyback transformer. 3. **Common Mode Chokes:** Used for EMI filtering to suppress noise in power lines. 4. **Coupled Inductors:** Ideal for circuits requiring multiple outputs or energy storage. --- ### 4.
