The **RP-08-R-T** typically refers to a high-precision, thin-film surface mount resistor. While part numbering can vary slightly between manufacturers (such as Viking Tech or Susumu), this specific nomenclature follows a standard industrial format for precision components. --- ### 1. Part Number Breakdown The alphanumeric code describes the physical and electrical characteristics of the component: | Segment | Meaning | Common Specification | | :--- | :--- | :--- | | **RP** | Series Code | High Precision Thin Film Chip Resistor | | **08** | Case Size | 1206 Imperial (3216 Metric) | | **R** | Resistance Value | "R" acts as a decimal point (e.g., 10R0 = 10 $\Omega$) | | **T** | Packaging | Tape & Reel (T) | --- ### 2. Technical Specifications Thin-film resistors like the RP-08 series are chosen for applications requiring high stability and low noise. * **Technology:** Thin Film (Metal Layer sputtered onto a ceramic substrate). * **Case Size:** 1206 (Dimensions: 3.2mm x 1.6mm). * **Typical Tolerance:** Often available in $\pm$0.1% or $\pm$0.05% (very high accuracy). * **Temperature Coefficient (TCR):** Usually low, ranging from 10ppm/°C to 50ppm/°C. * **Power Rating:** Typically 1/8W (0.125W) or 1/4W depending on specific sub-series. --- ### 3. Comparison: Thin Film vs. Thick Film The RP series (Thin Film) is significantly more advanced than standard "General Purpose" resistors. | Feature | Thin Film (RP-08) | Thick Film (Standard) | | :--- | :--- | :--- | | **Precision** | Very High (0.01% - 0.1%) | Moderate (1% - 5%) | | **Noise** | Extremely Low | Higher | | **Stability** | Excellent over time/temp | Moderate | | **Cost** | Higher | Very Low | --- ### 4. Common Applications Due to its precision, the RP-08-R-T is found in: 1. **Medical Equipment:** High-accuracy monitoring devices. 2. **Instrumentation:** Multimeters and calibration tools. 3. **Audio Circuits:** Low-noise signal processing. 4. **Power Management:** Precise voltage sensing and current shunts. ---
