The **V2-R56-R** is a specific electronic component, most commonly identified as a **high-precision, metal film resistor**. These parts are frequently used in industrial control systems, medical devices, and precision measurement tools due to their stability and low tolerance. --- ### Technical Specifications Below are the typical electronic characteristics for the R56 (0.56 Ohm) resistor within the V2 series: | Parameter | Specification | | :--- | :--- | | **Resistance Value** | 0.56 $\Omega$ (indicated by R56) | | **Series** | V2 (High Precision Metal Film) | | **Tolerance** | $\pm$1% or $\pm$0.5% (common for V2 series) | | **Power Rating** | 0.25W to 0.5W (depending on physical size) | | **Temp. Coefficient** | $\pm$50ppm/°C to $\pm$100ppm/°C | | **Material** | Metal Film | --- ### Key Electronic Functions 1. **Current Sensing:** Because of its low resistance value (0.56 $\Omega$), this part is often used as a **shunt resistor**. Engineers place it in series with a load to measure the voltage drop across it, thereby calculating the current flow. 2. **Voltage Regulation:** It acts as a precise voltage divider component in feedback loops for power supplies. 3. **Filtering:** When paired with a capacitor, it helps in RC (Resistor-Capacitor) circuits to filter out high-frequency noise in sensitive signal paths. ### Component Breakdown * **V2:** Represents the manufacturer-specific series or case style. This usually dictates the physical dimensions and the environmental ruggedness (e.g., flameproof coating). * **R56:** The resistance code. The "R" acts as the decimal point. * $R56 = 0.56 \Omega$ * $5R6 = 5.6 \Omega$ * $56R = 56 \Omega$ * **-R:** Usually signifies **RoHS Compliance** (Restriction of Hazardous Substances) or **Reel** packaging for automated SMT assembly. --- ### Application Example (Circuit Implementation) If used in a current sensing application, the circuit logic would look like this: ```python # Ohms Law Calculation: V = I * R resistance = 0.56 # Ohms measured_voltage = 0.28 # Volts measured across the R56 resistor current = measured_voltage / resistance print(f"The current flowing through the circuit is {current} Amperes.") # Output: 0.5 Amps ```
