Based on electronic component nomenclature and common industry standards, the part number **5CA-56-R** typically refers to a **High-Current Power Inductor** (often from manufacturers like Chilisin or similar magnetics providers). Below is a breakdown of the specifications and technical details associated with this component. --- ### 1. Technical Specifications The part is designed for surface-mount technology (SMT) and is used primarily for power management and noise filtering. | Parameter | Typical Value | Unit | | :--- | :--- | :--- | | **Inductance** | 56 | µH | | **Tolerance** | ±20% (Standard for Power Inductors) | % | | **Mounting Type** | Surface Mount (SMD/SMT) | - | | **Core Material** | Ferrite | - | | **Shielding** | Shielded (Reduces EMI) | - | | **RoHS Status** | Compliant (indicated by "-R") | - | --- ### 2. Part Number Breakdown The code can be decoded as follows to understand the manufacturing logic: * **5CA**: This usually denotes the **Series/Size**. The "5" often refers to the physical dimensions (e.g., approximately 5mm x 5mm footprint). * **56**: This represents the **Inductance Value**. In this case, it is 56 microhenries (µH). * **-R**: This suffix typically stands for **RoHS Compliant** (Lead-free) or, in some specific catalogs, **Tape & Reel** packaging. --- ### 3. Key Applications These components are essential in modern electronics for stabilizing voltage and filtering signals. * **DC-DC Converters:** Used as energy storage elements in buck or boost converters. * **Power Supplies:** Found in laptops, LED drivers, and networking equipment. * **EMI Suppression:** Filtering high-frequency noise in power lines to prevent interference with other components. * **Consumer Electronics:** Integrated into motherboards and portable devices where space is limited but high current is required. --- ### 4. Physical Characteristics As an SMD part, it features: * **Magnetic Shielding:** Prevents the magnetic field from interfering with nearby sensitive components. * **Low DCR (DC Resistance):** Designed to minimize power loss as heat, increasing the efficiency of the power circuit. * **High Saturation Current:** Capability to handle peak currents without the inductance dropping significantly. ---
