The **G6WU-1F-R** is a high-frequency, surface-mount (SMT) relay manufactured by **Omron Electronic Components**. It is specifically designed for switching high-frequency signals, commonly used in telecommunications and test equipment. --- ### 1. Key Technical Specifications | Parameter | Value / Description | | :--- | :--- | | **Contact Form** | SPDT (1 Form C) | | **Relay Type** | High Frequency (RF) | | **Impedance** | 75 $\Omega$ (Optimized for Video/Broadcast) | | **Coil Voltage** | Typically 3V, 9V, or 12V DC (depending on specific model suffix) | | **Frequency Range** | Up to 2 GHz | | **Mounting Type** | Surface Mount (SMT) | | **Terminal Shape** | Gull-wing terminals | --- ### 2. Core Electronic Features #### A. RF Performance The primary feature of the G6WU series is its ability to handle high-frequency signals with minimal loss. It boasts excellent isolation and insertion loss characteristics: * **Isolation:** Minimum 60 dB at 2 GHz. * **Insertion Loss:** Maximum 0.5 dB at 2 GHz. * **V.S.W.R.:** Low Voltage Standing Wave Ratio, ensuring signal integrity is maintained. #### B. Single-Side Stable Logic The "1F" in the part number often indicates a **single-side stable** (non-latching) configuration. This means the relay requires continuous power to the coil to maintain the "Set" position and will return to the "Reset" position automatically when power is removed. #### C. Environmental Durability The "R" suffix typically refers to the **Tape and Reel** packaging for automated pick-and-place assembly, but it also falls under Omron's standards for: * **Washability:** Usually fully sealed to allow for automatic soldering and cleaning processes. * **RoHS Compliance:** Lead-free construction. --- ### 3. Pinout and Internal Structure The device uses a specialized internal shielding structure to prevent electromagnetic interference (EMI) between the coil and the high-frequency signal path. ```mermaid graph LR A[Coil +] --- B(Electromagnet) C[Coil -] --- B D[Common] --- E{Switch} E --- F[Normally Closed] E --- G[Normally Open] ``` --- ### 4. Typical Applications * **Digital Broadcasting:** Switching between video signal paths in studio equipment. * **Test & Measurement:** Automated test equipment (ATE) for high-speed digital circuits. * **Telecommunications:** Signal routing in base stations or networking hardware.
