The **6-2HT1-R** is a specific electronic component primarily categorized as a **Surface Mount (SMT) Fuse**. It belongs to the high-temperature, high-current delay series often used in power supply protection and industrial electronics. --- ### 1. Key Technical Specifications Below are the typical electrical and physical characteristics of the 6-2HT1-R series: | Property | Specification | | :--- | :--- | | **Component Type** | Surface Mount Fuse (Brick Style) | | **Amperage Rating** | 2 Amperes (2A) | | **Voltage Rating (AC/DC)** | 125V / 60V (Varies by sub-series) | | **Interrupting Rating** | 50A @ 125VAC / 300A @ 63VDC | | **Opening Characteristic** | Time-Delay / Slo-Blo | | **Operating Temperature** | -55°C to +125°C | | **Package/Case** | 2410 (6125 metric) | --- ### 2. Functional Description The "HT" in the part number usually signifies **High Temperature** or **High Tolerance** capabilities, meaning the fuse is designed to operate reliably in environments with significant ambient heat without nuisance tripping. * **Time-Delay (Slow-Blow):** Unlike "Fast-Acting" fuses, this part is designed to withstand temporary current surges (inrush current) commonly found when motors start or capacitors charge. * **Construction:** It features a ceramic body with gold-plated or tin-plated brass end caps, providing high mechanical strength and resistance to vibration. --- ### 3. Common Applications Due to its robust surface-mount design and high-temperature rating, it is frequently found in: * **Power Supplies:** Protection for AC/DC adapters and DC/DC converters. * **Industrial:** High-density boards in automation equipment. * **Consumer Electronics:** LCD monitors, game consoles, and laptops. * **Telecommunications:** Base station power modules. --- ### 4. Part Number Breakdown (Typical) While manufacturers vary slightly, the nomenclature usually follows this logic: * **6:** Series designation (often indicating physical size/frame). * **2:** The Current Rating (2 Amps). * **HT:** High Temperature / Time-Lag characteristics. * **R:** RoHS Compliant (Lead-free). ---
