The **5EAG1-R** is a specific part number typically associated with **Littelfuse**, specifically within their **5x20mm Glass Body Cartridge Fuse** series. Below is a detailed breakdown of the electronic specifications and characteristics of this component. --- ## 1. Technical Specifications The "5EAG" series corresponds to the **229 Series** or similar high-quality glass fuses designed for supplementary protection in electronic circuits. | Feature | Specification | | :--- | :--- | | **Type** | Cartridge Fuse | | **Body Material** | Glass | | **Form Factor** | 5mm x 20mm | | **Response Characteristic** | Fast-Acting (F) or Medium-Acting | | **Amperage Rating** | 1 Amp (indicated by '1') | | **Voltage Rating** | Typically 125V or 250V AC | | **RoHS Compliant** | Yes (indicated by the '-R' suffix) | --- ## 2. Component Breakdown The part number follows a standard nomenclature used in industrial supply chains: * **5EAG**: Refers to the physical dimensions and the internal construction (Glass tube, nickel-plated brass end caps). * **1**: Denotes the current rating in Amperes ($1A$). * **-R**: Stands for **RoHS (Restriction of Hazardous Substances)** compliance, meaning it is lead-free. --- ## 3. Key Electronic Characteristics ### A. Fast-Acting Response As an "EAG" type glass fuse, it is generally designed to blow quickly when an overcurrent condition occurs. This protects sensitive semiconductor components that cannot withstand prolonged surges. ### B. Breaking Capacity (Interrupting Rating) This is the maximum current the fuse can safely interrupt without the glass body shattering. For these models, it is typically around **35A at 250V AC** or **10,000A at 125V AC**. ### C. Visual Inspection Because the body is made of clear glass, it allows for easy visual verification. If the internal filament is broken or if there is blackening inside the tube, the fuse has blown and must be replaced. --- ## 4. Common Applications These fuses are widely used in low-power consumer and industrial electronics: * **Power Supplies:** Protecting the input stage of AC/DC adapters. * **Control Circuits:** Safeguarding PLCs and industrial sensors. * **Consumer Goods:** Found in chargers, audio equipment, and small household appliances. ---
