The **CTS1F-R56K** is a specific electronic component belonging to the **inductor** family. Specifically, it is a subminiature, axial-leaded molded inductor typically used in high-frequency applications and signal processing. ### 1. General Specifications The part number follows a standard naming convention for fixed inductors. Here are the primary technical characteristics: | Parameter | Specification | | :--- | :--- | | **Component Type** | Fixed Inductor (Axial Leaded) | | **Inductance Value** | 0.56 µH (Microhenries) | | **Tolerance** | ±10% (Indicated by the 'K' suffix) | | **Core Material** | Phenolic or Ferrite (depending on specific series batch) | | **Package/Case** | Molded Axial (Cylindrical with leads on both ends) | --- ### 2. Part Number Breakdown Understanding the code helps in identifying the specific attributes: 1. **CTS1F**: The Series identifier. "CTS1" usually refers to the physical size and power rating (Small/Subminiature), while "F" often denotes a "Conformal" or "Flame retardant" coating. 2. **R56**: The Inductance value. The "R" acts as a decimal point. Therefore, **R56 = 0.56**. 3. **K**: The Tolerance code. * J = ±5% * **K = ±10%** * M = ±20% --- ### 3. Electrical Performance While exact ratings can vary slightly between manufacturers (like Central Technologies), typical performance for a 0.56µH axial inductor includes: * **Self-Resonant Frequency (SRF):** Usually very high (often >300 MHz), making it suitable for RF (Radio Frequency) circuits. * **DC Resistance (DCR):** Low resistance to minimize power loss. * **Rated Current:** Typically handles between 500mA to 1200mA depending on the specific wire gauge used inside. * **Quality Factor (Q):** High Q-factor at high frequencies, ensuring low energy dissipation in resonant circuits. --- ### 4. Common Applications Due to its small form factor and axial leads, the CTS1F-R56K is frequently found in: * **RF Tuning:** Used in filters and oscillators. * **Decoupling:** Filtering high-frequency noise out of power supply lines. * **Signal Conditioning:** Providing impedance matching in communication equipment. * **Consumer Electronics:** Found in older or through-hole PCB designs for TVs, radios, and monitors. ---
