The part number **014-R** typically refers to a **Thru-Hole Resistor**, specifically within the standard naming conventions used by various manufacturers (such as Ohmite, Xicon, or TE Connectivity) to denote a specific wattage and resistance tolerance. In most industrial contexts, the "014" prefix identifies the physical package size or power rating, while "R" denotes the resistance value or a RoHS compliance status. --- ### 1. Key Technical Specifications Based on the common industry standard for parts labeled 014-R, the typical specifications are: | Feature | Specification | | :--- | :--- | | **Component Type** | Fixed Resistor | | **Power Rating** | 0.25 Watts (1/4W) | | **Composition** | Carbon Film or Metal Film | | **Tolerance** | ±5% (Typical for Carbon) or ±1% (Metal Film) | | **Mounting Type** | Axial Lead (Through-Hole) | | **Temperature Range** | -55°C to +155°C | ### 2. Physical Construction The part is constructed with several layers to ensure stability and electrical performance: 1. **Ceramic Core:** A high-grade ceramic rod acts as the base. 2. **Resistive Element:** A thin film of carbon or metal is deposited onto the core. 3. **End Caps:** Metal caps are pressed onto the ends to connect the resistive element to the leads. 4. **Coating:** A flame-retardant epoxy or lacquer protects the internal film from moisture and oxidation. 5. **Color Bands:** The body features stripes to denote the resistance value (e.g., Brown, Black, Gold). ### 3. Common Applications * **Current Limiting:** Protecting LEDs or sensitive transistors from excessive current. * **Voltage Dividers:** Reducing voltage levels in signal processing circuits. * **Pull-up/Pull-down:** Ensuring digital logic pins are at a defined state (High or Low). * **Consumer Electronics:** Used extensively in power supplies, audio equipment, and toys due to low cost. --- ### 4. Identification Guide If you are looking at the component, the **014** code often maps to these manufacturer series: * **Xicon/Mouser:** Often represents the **271 (1/4W)** series where "014" is a shorthand for the wattage class. * **RoHS Suffix:** The **-R** suffix almost always indicates that the part is Lead-Free and meets "Restriction of Hazardous Substances" (RoHS) requirements. ---
