The **F2VF-5F-R** is a specific electronic component belonging to the **Subminiature Power Relay** category, typically manufactured by companies like **Goodsky** or similar industrial relay providers. Below is a detailed breakdown of its electronic specifications and characteristics. --- ## 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Component Type** | Electromechanical Relay | | **Mounting Type** | Through-Hole (PCB Mount) | | **Contact Configuration** | 1 Form A (SPST-NO) | | **Coil Voltage** | 5V DC | | **Contact Rating (Resistive)** | 5A @ 250V AC / 30V DC | | **Coil Power Consumption** | Approx. 200mW (Sensitive version) | | **Terminal Type** | Solder Terminals | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ## 2. Part Number Breakdown Understanding the nomenclature helps in identifying the exact variant: * **F2V**: The series identifier (Subminiature Power Relay). * **F**: Insulation System (often Class F, rated for higher temperatures, e.g., 155°C). * **5**: Nominal Coil Voltage (5 Volts Direct Current). * **F**: Contact Material / Suffix code (usually implies a specific flux-tight or sealed construction). * **-R**: RoHS Compliant (Lead-free). --- ## 3. Key Electronic Functions ### A. Low Power Consumption The "F2V" series is designed for efficiency. With a coil power of approximately **200mW**, it can be driven by low-power circuits, though a transistor (like a 2N2222) or a flyback diode is still required when interfacing with a microcontroller. ### B. High Isolation These relays are designed to provide high dielectric strength between the coil and the contacts (often up to 4,000V AC), ensuring that the low-voltage control side is safely isolated from the high-voltage load side. ### C. Compact Form Factor The "Subminiature" designation means it occupies minimal PCB real estate, making it ideal for: * Smart plugs and home automation. * Industrial PLC output modules. * Heating, Ventilation, and Air Conditioning (HVAC) controls. --- ## 4. Typical Application Circuit When using the F2VF-5F-R with a 5V MCU (like an Arduino), the following circuit is standard: ```text [MCU Pin] ---> [1k Resistor] ---> [Base of NPN Transistor] | [Relay Coil] <--- [Parallel Flyback Diode] | [Ground] ``` ---
