The **CTX10-1-52LP-R** is a specific electronic component manufactured by **Eaton (formerly Coiltronics)**. It belongs to the **OCTA-PAC® PLUS** series of power inductors and transformers. --- ### 1. Component Overview The CTX10-1-52LP-R is a **surface-mount (SMD) power inductor** known for its dual-winding design. This allows it to be used as a single inductor, two coupled inductors, or a 1:1 transformer. ### 2. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Inductance (Parallel)** | 10.1 µH (Nominal) | | **Inductance (Series)** | 40.4 µH (Nominal) | | **Current Rating (Parallel)** | ~1.62 Amperes | | **DC Resistance (DCR)** | ~0.063 Ohms (per winding) | | **Core Material** | Powdered Iron (Material -52) | | **Operating Temperature** | -40°C to +125°C | | **Package/Case** | Size 1 (Low Profile) | | **Termination** | RoHS Compliant (Lead-Free) | --- ### 3. Detailed Features * **Dual Winding Construction:** It consists of two separate windings on a single core. You can bridge the pins to create different configurations: * **Parallel:** Higher current capacity, lower inductance. * **Series:** Higher inductance, lower current capacity. * **Core Material (-52):** The "52" in the part number refers to the iron powder core material. This material is optimized for high-frequency applications (up to 500 kHz) and provides stable performance with low core losses. * **Low Profile (LP):** Designed for height-sensitive applications where vertical space is limited. ### 4. Common Applications 1. **DC-DC Converters:** Used in Buck, Boost, and SEPIC topologies. 2. **Power Supplies:** Acts as an output filter inductor to smooth out current ripples. 3. **Signal Isolation:** Can function as a 1:1 isolation transformer for low-power signals. 4. **Common Mode Choke:** When wired correctly, it can help suppress EMI (Electromagnetic Interference) on power lines. --- ### 5.
