The **F2VF-5WZ-R** is a specific electronic component, typically categorized as a **Signal Relay** manufactured by Fujitsu (though the series nomenclature is often part of the FTR-F2 family). These components are designed for high-density mounting and low power consumption in communication and control circuits. --- ### 1. Key Technical Specifications The following table outlines the primary electrical and physical characteristics of the F2VF-5WZ-R: | Feature | Specification | | :--- | :--- | | **Relay Type** | Polarized Signal Relay | | **Contact Form** | DPDT (2 Form C) | | **Nominal Coil Voltage** | 5V DC | | **Contact Rating** | 1A at 30V DC / 0.5A at 125V AC | | **Coil Sensitivity** | High Sensitivity (Approx. 140mW - 200mW) | | **Mounting Type** | Surface Mount (SMT) | | **Contact Material** | Gold-overlay silver alloy | --- ### 2. Detailed Component Breakdown #### A. Coil Characteristics The "5W" in the part number signifies a **5V DC** operating voltage with a "Wide" or "High Sensitivity" coil. * **Must Operate Voltage:** Usually 75% of nominal (approx. 3.75V). * **Must Release Voltage:** Usually 10% of nominal (approx. 0.5V). * The polarized nature means it uses a permanent magnet to assist the coil, reducing the energy required to switch states. #### B. Contact Configuration (DPDT) This part features **Double Pole Double Throw** (2 Form C) contacts. This means it can control two separate circuits simultaneously, switching each between a "Normally Closed" and a "Normally Open" contact point. #### C. Physical Construction * **Washable Design:** The "R" or specific suffix often denotes tape-and-reel packaging or a construction that is sealed to allow for automated solder washing processes. * **Compact Footprint:** Designed for space-constrained PCB applications like telecommunications equipment or handheld testing devices. --- ### 3. Common Applications Due to its signal-level switching capabilities and low power draw, this relay is found in: 1. **Telecommunications:** Switching line signals or test access. 2. **Medical Equipment:** Low-power signal routing in diagnostic tools. 3. **Security Systems:** Control interfaces for alarm panels. 4. **Measurement & Control:** Used in PLCs (Programmable Logic Controllers) for small signal switching. ---
