The **CTX0.68-1P-R** is a specific electronic component belonging to the **CTX Series** of high-power, surface-mount (SMT) inductors, manufactured by **Eaton (formerly Cooper Bussmann/Coiltronics)**. --- ### 1. Key Technical Specifications The part number itself contains encoded information about its electrical characteristics. | Parameter | Value / Description | | :--- | :--- | | **Inductance** | 0.68 µH (Microhenries) | | **Tolerance** | ±20% (Standard for this series) | | **Current Rating (Isat)** | ~18A to 25A (Depending on temperature rise) | | **DC Resistance (DCR)** | Extremely Low (typically < 2.0 mΩ) | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Shielding** | Magnetically Shielded | --- ### 2. Physical Construction and "1P" Designation The "1P" in the part number refers to the **Octa-Path** or specialized footprint configuration often found in the **Power-Plus** series. * **Core Material:** Ferrite core for low core losses at high frequencies. * **Design:** These are often "Flat-Pac" or high-profile inductors designed to handle high current ripples without saturating quickly. * **RoHS Compliant:** The "-R" suffix indicates that the part is Lead-Free and RoHS compliant. --- ### 3. Common Applications Due to its very low inductance (0.68 µH) and high current capability, this part is typically found in: 1. **Voltage Regulator Modules (VRMs):** Used in CPUs and GPUs where high current and fast transient response are required. 2. **DC-DC Converters:** High-frequency switching power supplies. 3. **Point of Load (POL) Converters:** Providing stable power near the integrated circuits on a PCB. 4. **Multi-phase Buck Converters:** Used in servers and telecommunication equipment. --- ### 4.
