The **2410FA2-5-R** is a specific surface-mount fuse manufactured by **Eaton (formerly Bussmann)**. It belongs to the 2410 (6125 metric) series, known for being a "Fast-Acting" (FA) Wire-in-Air (WIA) fuse. --- ### ## Technical Specifications Below is a breakdown of the key electrical and physical attributes of the 2410FA2-5-R: | Attribute | Specification | |:---|:---| | **Series** | 2410FA (Fast Acting) | | **Current Rating** | 5 Amperes | | **Voltage Rating (AC)** | 125 Vac | | **Voltage Rating (DC)** | 125 Vdc | | **Package / Case** | 2410 (6125 Metric) | | **Interrupting Rating** | 50A @ 125Vac / 50A @ 125Vdc | | **Typical Resistance** | 0.015 Ohms | | **Operating Temp** | -55°C to +125°C | | **RoHS Compliant** | Yes (Lead-Free) | --- ### ### Component Breakdown & Part Number Logic To understand this specific part, we can deconstruct the nomenclature: 1. **2410**: Refers to the physical size in inches (0.24" x 0.10"). In metric, this is **6125** (6.1mm x 2.5mm). 2. **FA**: Stands for **Fast-Acting**. This fuse is designed to blow quickly when an overcurrent occurs, protecting sensitive downstream electronics. 3. **2**: This refers to the specific design version or termination style (Silver-plated brass endcaps). 4. **5**: Represents the **Current Rating** (5 Amps). 5. **-R**: Indicates that the part is **RoHS compliant**. --- ### ### Key Features and Applications #### **Features** * **Wire-in-Air Design:** This construction provides excellent inrush current withstand capability and high reliability. * **Surface Mount:** Compatible with automated pick-and-place assembly and infrared/vapor phase reflow soldering. * **Safety Approvals:** Typically UL Recognized and CSA Certified. #### **Common Applications** * **LCD Monitors & Backlight Inverters:** Protecting the power rails of display panels. * **Server Power Supplies:** Used on secondary side circuits. * **Medical Equipment:** General circuit protection in portable devices. * **Battery Chargers:** Preventing thermal runaway or fire in the event of a component failure. --- ### ### Comparison: Fast-Acting vs. Time-Delay The **FA** in 2410FA2-5-R is critical. If your circuit has high "inrush" currents (like a motor starting up), a Fast-Acting fuse might blow prematurely. However, for digital logic boards or power supplies where a fault must be cleared instantly to prevent fire or further damage, Fast-Acting is the preferred choice.
