The **TS2043G-R16-R** is a specific surface-mount electronic component, typically categorized as a **Tactile Switch**. These components are widely used in consumer electronics, automotive controls, and industrial interfaces to provide physical feedback to the user upon a button press. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here are the primary specifications: | Feature | Specification | | :--- | :--- | | **Type** | Tactile Switch (Momentary) | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Circuit** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Actuator Type** | Standard Round Button | | **Operating Force** | Typically 160gf or 250gf (R16 often denotes 160g force) | | **Dimensions** | 4.5mm x 4.5mm (common for this series) | | **Packaging** | Tape & Reel (TR) | --- ### 2. Breakdown of Part Number Parts Manufacturers use specific codes to define the mechanical and electrical properties of the switch: * **TS**: Tactile Switch series designation. * **2043**: Internal design/frame size code (4.5 x 4.5 mm footprint). * **G**: Often refers to the terminal plating (e.g., Gold or Silver) or a "G-wing" SMT lead shape. * **R16**: Represents the **Actuation Force**. In this case, it usually signifies **160 grams-force (gf)**. * **R**: Indicates the packaging method, specifically **Reel** (Tape & Reel) for automated pick-and-place assembly. --- ### 3. Electrical and Mechanical Characteristics To ensure the part fits your PCB design, consider these typical limits for the TS2043 series: * **Contact Rating:** 50mA @ 12V DC. * **Contact Resistance:** ≤ 100mΩ. * **Insulation Resistance:** ≥ 100MΩ @ 100V DC. * **Life Expectancy:** 50,000 to 100,000 cycles (depending on force). * **Travel:** 0.25mm ± 0.1mm. --- ### 4. Typical Applications Because of its small footprint and SMT design, it is found in: 1. **Consumer Electronics:** Remote controls, cameras, and handheld gaming devices. 2. **Peripherals:** Computer keyboards (function keys) or mouse buttons. 3. **Industrial:** Reset buttons on PCBs and interface panels. ---
