The **FP2-V050-R** is an electronic component primarily classified as a **High-Voltage Resistor** or a **Power Metal Film Resistor**, typically manufactured by companies like Vishay Dale. These resistors are engineered for high-precision applications requiring stability under high voltage and thermal stress. --- ### 1. Key Technical Specifications The "FP" series stands for "Flameproof," indicating safety features under overload conditions. | Parameter | Specification | | :--- | :--- | | **Series** | FP (Flameproof Metal Film) | | **Power Rating** | 2 Watts (at 70°C) | | **Resistance Value** | 50 Ohms (implied by "050") | | **Tolerance** | Usually ±1% or ±5% (depending on the suffix) | | **Coating** | Flameproof silicone-base coating | | **Mounting Type** | Through-hole (Axial leads) | --- ### 2. Physical and Material Construction The FP2-V050-R is built to withstand harsh electrical environments through a specific layering process: 1. **Core:** High-grade ceramic rod. 2. **Resistive Element:** A metal film or metal oxide film deposited onto the ceramic. 3. **End Caps:** Tin-plated copper leads are pressed onto the ends for a secure mechanical and electrical connection. 4. **Coating:** The "R" in the suffix often denotes compliance with environmental standards (RoHS) or specific protective resins that prevent the component from catching fire if it fails. --- ### 3. Applications and Usage Due to its high power-to-size ratio and flameproof characteristics, it is commonly found in: * **Power Supplies:** Used as a bleeder resistor or in voltage dividers. * **Industrial Controls:** Signal conditioning in high-voltage circuits. * **Safety Circuits:** Where a component failure must not result in a fire (the resistor will open-circuit safely). * **Consumer Electronics:** High-end audio or power management stages. --- ### 4. Part Number Breakdown While manufacturer codes vary slightly, the standard breakdown for the FP2 series is: * **FP:** Flameproof Series. * **2:** Power rating (2 Watts). * **V:** Often refers to a specific lead configuration or voltage rating. * **050:** The resistance value (50 $\Omega$). * **R:** Packaging code (e.g., Tape & Reel) or RoHS compliance.
