The term **0206-R** typically refers to a specific component nomenclature used in industrial electronics, most notably associated with **protective fuses** (specifically subminiature or surface-mount types) or specialized **resistor networks**. Below is a breakdown of what this part represents, focusing on its most common application in the electronics industry. --- ## 1. Primary Identification: Subminiature Fuses In most electronic contexts, `0206-R` is a part number suffix or series designation for **Bussmann (Eaton)** or similar subminiature, through-hole fuses (often called "TR5" or "TE5" styles). ### Technical Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Radial Lead Subminiature Fuse | | **Package Style** | Circular or Rectangular (Through-hole) | | **The "-R" Suffix** | Usually denotes **RoHS Compliance** (Lead-free) | | **Typical Voltage** | 250V AC (commonly) | | **Breaking Capacity** | High interrupt ratings for power supply protection | --- ## 2. Key Characteristics If you are looking at a circuit board and see a part labeled with this series, it possesses the following traits: * **Time-Lag (Slo-Blo):** These parts are often designed to withstand brief surges (like a motor starting) without blowing, but will trip if a sustained overcurrent occurs. * **Space Efficiency:** Designed to occupy minimal PCB "real estate" compared to traditional 5x20mm glass fuses. * **Flammability Rating:** Usually housed in a UL 94-V0 thermoplastic package. --- ## 3. Alternative Interpretation: SMD Passive Components In rare cases, "0206" might refer to an **Imperial/Metric Package Size**, though it is non-standard (0201 and 0402 are standard). However, if used as a code for a resistor: 1. **02**: Refers to length (0.02 inches). 2. **06**: Refers to width (0.06 inches). 3. **R**: Often used as a decimal point in resistance values (e.g., `2R0` = 2.0 Ohms). --- ## 4. Common Applications * **Power Supplies:** Protecting the input stage of AC/DC converters. * **Consumer Electronics:** Used in chargers, LED drivers, and white goods. * **Industrial Controls:** Protecting PLCs and sensor arrays from short circuits. --- ### How to verify your specific part: To be 100% certain, check the **Brand Logo** on the component: * **"B" in a circle:** Eaton/Bussmann (Fuse). * **"LF":** Littelfuse (Fuse). * **Plain Numbers:** Likely a resistor or capacitor.
