## G3T25AP-R Electronic Component Overview The **G3T25AP-R** is a specific model of a **subminiature toggle switch** manufactured by **NKK Switches**. It is designed for logic-level applications and is known for its high reliability and ultra-compact surface-mount design. ### 1. Key Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | NKK Switches | | **Switch Function** | DPDT (Double Pole Double Throw) | | **Switch Operation** | ON-NONE-ON | | **Current Rating** | 0.4VA Max @ 28V AC/DC Max | | **Mounting Type** | Surface Mount (SMD) - Gull Wing | | **Actuator Type** | Standard Lever (Antistatic) | | **Terminal Type** | PC Pin (Gull-wing for SMD) | --- ### 2. Physical & Material Characteristics * **Antistatic Actuator:** The toggle is made of carbon-impregnated polyamide, which provides protection against electrostatic discharge (ESD) to the internal contacts. * **Sealed Construction:** The device features an ultrasonic welding of the case and cover, and an epoxy seal at the base. This makes it **washable**, allowing it to withstand automated soldering and cleaning processes. * **Subminiature Size:** It belongs to the "G3T" series, which is one of the smallest toggle switch families available, ideal for high-density PCB layouts. --- ### 3. Electrical Behavior This switch is designed for **Logic Level** circuits. It uses gold-plated contacts to ensure conductivity even at very low voltages and currents. * **Contact Resistance:** 80 milliohms maximum. * **Insulation Resistance:** 500 Megohms minimum @ 500V DC. * **Mechanical Life:** 50,000 operations minimum. * **Electrical Life:** 50,000 operations minimum. --- ### 4. Typical Applications Because of its size and ESD protection, the G3T25AP-R is commonly found in: * Handheld medical devices. * Telecommunications equipment. * Portable test and measurement instruments. * Compact industrial control panels. --- ### 5.
