The **CTC2F-R056M** is a high-performance **shielded surface mount (SMD) power inductor** typically manufactured by companies like Central Technologies. It is designed for high-density circuits where electromagnetic interference (EMI) must be minimized. --- ### 1. Technical Specifications The part number follows a specific nomenclature. Here is the breakdown of its key electrical characteristics: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.056 µH (56nH) | | **Tolerance** | ±20% (indicated by 'M') | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Shielding** | Magnetically Shielded | | **Core Material** | Ferrite | | **Operating Temp** | -40°C to +125°C (typical) | --- ### 2. Part Number Deciphering Understanding the alphanumeric code helps in identifying the component's physical and electrical properties: * **CTC2F**: Series designation (likely a specific size/package style, e.g., 0805 or 1210 equivalent). * **R056**: The inductance value. "R" acts as the decimal point (0.056). * **M**: The tolerance code. In the electronic component world, 'M' stands for ±20%. --- ### 3. Key Features & Applications #### Features: * **Low Profile:** Designed for compact electronic assemblies like smartphones and tablets. * **Magnetic Shielding:** The ferrite construction contains the magnetic field, preventing the inductor from interfering with nearby sensitive components. * **High Current Capability:** Despite its small size, it is designed to handle significant DC currents without saturating the core. #### Common Applications: 1. **DC-DC Converters:** Used for energy storage and voltage regulation. 2. **Filtering:** Effective at removing high-frequency noise from power lines. 3. **Mobile Electronics:** Ideal for laptops, SSDs, and handheld devices where space is at a premium. 4. **Telecom:** Used in base stations and networking hardware. --- ### 4. Comparison with Non-Shielded Inductors | Feature | CTC2F-R056M (Shielded) | Standard Unshielded Inductor | | :--- | :--- | :--- | | **EMI Leakage** | Very Low | High | | **Cross-talk** | Minimal | Potential for interference | | **Size** | Slightly larger/heavier | Smaller profile | | **Cost** | Slightly higher | Lower |
