The **TR2-6-R** is a specific electronic component belonging to the **TR2 Series** of subminiature, through-hole fuses. It is manufactured by **Eaton (formerly Bussmann)**. Below is a detailed breakdown of its specifications, physical properties, and typical applications. --- ## 1. Technical Specifications The part number "TR2-6-R" encodes specific electrical characteristics. | Parameter | Specification | | :--- | :--- | | **Component Type** | Subminiature Through-Hole Fuse | | **Current Rating** | 6 Amperes (6A) | | **Voltage Rating (AC)** | 125 Volts | | **Voltage Rating (DC)** | 125 Volts | | **Fuse Characteristic** | Time-Delay (Slow Blow) | | **Interrupting Rating** | 50A at 125Vac/dc | | **Resistance (Typical)** | ~0.010 Ohms | | **RoHS Compliant** | Yes (Indicated by the "-R" suffix) | --- ## 2. Physical Characteristics The TR2 series is designed for space-constrained PCB (Printed Circuit Board) layouts. ### Form Factor * **Package Type:** Subminiature radial leaded (often referred to as a "micro fuse"). * **Body Material:** Thermoplastic body with tin-plated copper leads. * **Mounting:** Through-hole soldering. ### Dimensions (Approximate) * **Diameter:** ~8.5 mm * **Height:** ~8 mm * **Lead Spacing:** 5.08 mm --- ## 3. Key Performance Features 1. **Time-Delay (Slow-Blow):** Unlike "Fast-Acting" fuses, the TR2-6-R can withstand temporary current surges (inrush current) without blowing. This is essential for circuits containing motors or capacitors that draw high current momentarily upon startup. 2. **Board Space Efficiency:** Its vertical orientation and small footprint save significant "real estate" on a PCB compared to traditional glass tube fuses and clips. 3. **Reliability:** It is designed to meet UL 248-14 standards for supplemental overcurrent protection. --- ## 4. Typical Applications The TR2-6-R is commonly found in the following electronic environments: * **Power Supplies:** Protecting the input/output stages of AC-DC adapters. * **Consumer Electronics:** Televisions, monitors, and audio equipment. * **Industrial Controllers:** Protecting sensitive logic boards from overcurrent events. * **Chargers:** Battery charging circuits where moderate current (6A) is managed. ---
