The term **01C-R** typically refers to a specific marking or package code used for Surface Mount Device (SMD) resistors, specifically those following the **EIA-96 marking standard**. --- ## 1. Deciphering the Code (EIA-96 Standard) In the EIA-96 marking system, three characters are used to represent precise resistance values (1% tolerance). The code is broken down into two parts: the **Value Code** and the **Multiplier**. | Code Segment | Component | Meaning | | :--- | :--- | :--- | | **01** | Value Code | Represents the number **100** | | **C** | Multiplier | Represents **x100** ($10^2$) | | **-R** | Suffix | Usually denotes "RoHS Compliant" or "Reel" packaging | ### Calculation: $$100 \times 100 = 10,000 \Omega \text{ (or 10k}\Omega\text{)}$$ --- ## 2. Technical Specifications Components marked with 01C are standard precision resistors found in compact electronic circuits. | Feature | Specification (Typical) | | :--- | :--- | | **Resistance** | 10k Ohms | | **Tolerance** | ±1% (Standard for EIA-96) | | **Package Size** | Usually 0603 (1608 Metric) | | **Power Rating** | 1/10W (0.1W) | | **Temperature Coefficient** | ±100ppm/°C | --- ## 3. Usage and Identification Because the 0603 package is too small to print "10000" or "10k," manufacturers use these shorthand codes. ### Code Breakdown Table for Multipliers: If the letter suffix changes, the value changes significantly: | Letter | Multiplier | Result for "01" | | :--- | :--- | :--- | | **A** | 1 ($10^0$) | 100 $\Omega$ | | **B** | 10 ($10^1$) | 1k $\Omega$ | | **C** | 100 ($10^2$) | **10k $\Omega$** | | **D** | 1000 ($10^3$) | 100k $\Omega$ | --- ## 4. Part Number Example In a bill of materials (BOM), you might see this represented as: `RC0603FR-0710KL` * **RC**: Resistor Chip * **0603**: Size * **F**: 1% Tolerance * **R**: Paper Tape / Reel * **10K**: The actual value ---
